9/14/2017 – We are just starting to defoliate a little cotton. Mainly on the west side of my area along the Ms River. Early planted cotton took a big hit with boll rot and hard lock. Cotton should still be fair but definitely nowhere close to what it was. Ready to look at with leaves off and hopefully more will fluff out than we think. We will defoliate a lot more in 10-14 days that will be a little better cotton. Still spraying stink bugs in late planted stuff.
A few soybeans will be desiccated this week. Still fighting red banded in most areas. Lots of beans are just at R5. Very few acres cut. Yields have been in mid 50’s with 5-15% damage.
Growers are trying to dig peanuts in a few places. Some too wet, some too dry. None are really showing ready but we’ve got to get started to make sure we aren’t late on the tail end. Some of these fields are 150 days old today and show to be 14 days away still. Yields look absolutely wonderful. Just need right conditions to get out.

9/14/2017 – In 1991, I was in my 8th year as a licensed Ag Consultant. I remember being through scouting all my cotton fields by August 15. Our yields were considerably less that year than the yields we will average in 2017; however, other than a little boll rot in the bottom canopy we didn’t see Bacterial Blight- didn’t even know what Target Spot or Stemphylium was – and the foliage seemed to stay with the plant until we defoliated it off. I never remember seeing mature bolls on the ground during the last few weeks of the season. In 1991, I had very few fields with over 16 oz. of Pix per acre total. We started off with what was called “low rate multiples” where our first apps would be 2 or 4 oz. This year I have many acres with well over 100 oz. and some of my first shots were 14 oz. at node 8! And the cotton was still very difficult to control. We are certainly living in better times for growing profitable cotton – the technology has made life easier on all of us. However, we have paid a great price for all that we have gained: qualities such as earliness, disease resistance, and ease of management seem to have been overlooked when our seed companies select their offerings for our growers. I hope that before my career ends I will have a year where I can look out across my fields on August 15 and see maturing cotton changing colors- bolls beginning to open – between waist and shirt pocket high laying around in the middles so light can get into the canopy that is full of foliage and speckled bolls. Not green cotton full of new growth that needs a quart of Pix to slow down the growth.

9/14/2017 – Soybean yields have been really good overall. WE are just ready to be done with all of them. Tired of the RBSB! I’m hoping we can find out some more info on this pest this winter. Our growers hate it.
Drained my very last rice field and still have some harvest going on. In general, yields have been average to great.
Cotton defoliation will start in the next week or so. It’s been a long, long season and we are all ready to see this one end! Time to hit the woods and relax! (after I soil sample some).

Reporting from the North Delta, Tucker Miller, Drew
9/14/2017 – 2017 overview:
Cotton: starting to defoliate this past week, and will start most defoliant next week around September 20.
Main problems I had this season were resistant worms to Bollgard II, controlling plant growth with PGR’s, and bacterial blight as well as target spot.
Soybeans— most beans were planted in the first 15 days of April, which led to very good yields – mostly in the 80’s. Red banded sting bugs were an issue mostly south of Highway 82 and in later beans. Sprayed most acres one time and some twice. Loopers were also widespread in the later beans. Insecticide ran short in several cases on late planted beans.
Corn — all harvested, best yields in several years. Probably due to good weather. Most averages around 220 bushels.
Peanuts— 115-120 days. Saw more leaf spot this year in my area. Will blast some the first of next week.

9/5/2017 – Rice – all of my acres have been drained. About 60-70% has been harvested. Harvest is about on schedule. Yields have been really good so far. We had good temperatures and no rain during the middle of the day while the crop was heading.
Soybeans – almost all of my May planted beans have been treated for RBSB. Some fields have been sprayed twice. Irrigation has been terminated on all of my acres. The two things that stick out about this year are dicamba drift and the RBSB.

Reporting from East Mississippi, Phillip McKibben, Maben
9/7/2017 – We’ve been spraying Gramoxone and cutting beans as the weather has allowed, but trying not to get too far ahead of the combine with all of the rain that we’ve had in the past 2 weeks. Yields have been really good, but evidently not quite as good as some growers thought (I had one grower disappointed when a dryland field averaged “only” 70 bushels).
Later beans got hammered by Loopers a couple weeks ago, and now Red-Bands are moving into some fields that are approaching R6, and we’re taking them out.
Corn yields have all been good, but some fields have yielded 300+ bushels (some dryland), and we’re trying to sort out some common factors to exploit in the future. I believe that drainage (surface as well as internal) is a key component in this variation.
Our cotton crop is still good, but might not be as ‘great’ as it appeared the first of August. We’ve terminated all insect control, and are beginning to monitor NACB and open boll percentages.
This sweet potato crop was greatly altered by the heavy rains that we received the first half of August. There are some fields that lost 75% of the harvestable yield due to excessive rotting. Many fields have some measure of ‘water damage’, Southern Blight, and bacterial rots, which are often not detected during harvest, but will cause the roots to break down in the bins during storage (especially if moved directly into curing rooms). With this type of damage, the full effects will not be known for several months, as the bulk of this (and every) crop will be stored until the Thanksgiving and Christmas markets. When the potatoes are fully cured, washed, graded, and packed… that’s when the pain is felt. We are roughly 20% harvested, and some growers are in salvage mode already.

Reporting from the South Delta, Andy Tonos, Greenville
9/9/2017 – Corn crop was good – all yields were great.
Rice yields have been good overall. Still have some later crop in the field. Unfortunately, some of this is due to Hurricane Harvey.
Soybean yields have been good to great, taking some damage due to weather. Nothing unacceptable overall but hoping for a break next year with RBSB.
Cotton is starting to open but still 1-2 weeks away from defoliation.

8/28/2017 – Cotton- I have terminated my April cotton. I will continue to take care of my young cotton for a while longer. Looking at the long range weather forecast, I will have to make a decision whether to continue with applications. Diseases have taken a toll on my cotton. My cotton started shedding bolls due to diseases about 2 weeks ago.
Soybeans- I have sprayed all young beans for loopers and stink bugs. The loopers helped with the decision to spray red banded stink bugs. Soybean harvest is being delayed due to weather, but yields have been excellent.
Corn- My corn is 50-60% harvested. Yields are good, 200 + bushels per acre.

Reporting from the South Delta, Billy Bryant, Greenwood
8/30/2017 – Bollworm egg lay has ceased in my territory as of 8-27-17 and worms under control from recent sprays. Plant bugs flared up in greenest cotton last week due to showers occurring on Acephate tank mixtures- had some high numbers and zeroed them out with Bifenthrin + 1 lb of Acephate in 5 gpa. Some green cotton will likely be treated again if egg lay resumes but majority of acreage has seen the last poison. Boll rot along with disease has taken the crop backwards somewhat but we still have a good crop overall. Target spot has not yet affected our youngest cotton and it looks extremely good at this time. How fast the ground dries out following the tropical system that is moving through now will dictate how well our older cotton does.
Sweeping beans right up to harvest or desiccation – spraying Redbanded Stinkbugs somewhere every day. Green R5 beans getting re-entry 10 days following treatment in many cases. Let some 2’s go on some beans for 2 weeks prior to harvest and damage did not show up in the samples. Mainly treating 3’s and upward if beans are in the R7 stage. A tremendous amount of soybeans will be desiccated after Harvey passes. Have Bifenthrin tank mixed with some but most acreage will not require poison due to very low numbers of RBSB due to recent sprays. What few fields that have been harvested have turned out with very good yields.
White mold has appeared on some fields that have been rotated with peanuts in the past despite two earlier apps of Convoy + Bravo. Got all treated with Elatus but surprisingly enough did not receive proper rainfall to fully activate. We stopped the progression of the white mold with that treatment but have come back on the affected acreage on 14 days with another shot in front of the moisture expected from Harvey. Will be able to begin digging on our oldest peanuts around 9-10-17 based on what I see from scratch tests this week. Will blast some fields next week to verify this.

Reporting from the North Delta, Joseph Dean, Cleveland
9/1/2017 – Most of my cotton is finished and safe from insects. Target spot is bad and there are a few bolls dropping in the worst areas. Also had a little boll rot before Harvey arrived and expect to see more now.
Beans range from early R5 to harvested. Yields have been really good so far. Red banded stinkbugs have been persistent in areas. I’ve also had to treat a large percentage of the May planted beans for loopers.
95% plus of the corn I check has been harvested. Yields were well above average.
All of my rice is drained now and a fair amount lodged with the rain and wind Thursday.

Reporting from the South Delta, Jason Grafton, Madison
9-3-14 Cotton- Still have a few plantbug treatments going out on some acres but a lot of this crop is getting close to the end. A few fields should be ready for defol in 10-14 days. It’s hard to gauge this crop but I believe it’s still a great crop with all it’s been through. I’m just glad to see some sunshine in the forecast.
Soybeans- We used to say when beans get ready you got to get them out before weather gets them. I’m thinking these RBSB’s are worse than the weather. In saying that, I’m now looking at beans until I see a combine in the field. Hoping the sun stays out so harvest can stay rolling and hoping for a hard winter!

8/28/2017 – Nothing has really changed since my last crop report. Growers were finally able to stand up in fields today and get some fungicides on peanuts. They sprayed lots of acres in a misting rain. Hopefully it stuck. Weather man says 3-6 inches through Thursday. I guess we will wait and see. Most of my soybeans have been sprayed in the last 7 days so maybe they will be okay for a few days. Boll rot and hard lock just seems to get worse every day and the next few aren’t gonna help a bit. Hate to gripe much after seeing what Houston and surrounding area is going through. We all need to be thankful that we’re not in that mess and lift them up in prayer. I am soooooo ready to get this one over with.

Reporting from East Mississippi, John Clark Cook, Vaiden
8/28/2017 – Corn: Harvest is at a standstill now; yields have been good so far. Still have a ways to go.
Cotton: From target spot, bacterial blight and boll rot, this is not a very pretty crop to look at. Hopefully it will turn out like last year’s crop which was great even though it looked horrible. Younger cotton still getting high rates of PGR and insects monitored closely, older cotton has been cut loose. Just need rains to let up.
Soybeans: 95% of what I check has been treated for RBSB at least once and some twice. The other 5% will get treated in the near future. My new threshold for them is the following: Find 1 – call the grower, Find 2 – put the plane on notice, Find 3 – send the chemical to the strip, Find 4 – TREAT. This is on a field basis; forget this per 25 sweeps crap! So far the little bit that has been harvested has been really good.
Peanuts: Look good so far, starting to pick up more leaf spot over the past week.

Reporting from the South Delta, Clay Horton, Greenwood
8/29/2017 – At least 75% of my corn acres have been harvested with yields well above average thus far.
Group 3 soybeans and the first of April planted G4’s have been harvested with good yields reported. I have a large percentage of my acres that I will desiccate behind TS Harvey. R5.7-6 beans have been treated for loopers and many for RBSB. Pressure in my area has been light compared to what I’m hearing elsewhere.

Reporting from the South Delta, Dee Boykin, Yazoo City
8/29/2017 – Corn – Most of my growers have completed their corn harvest and are very pleased with the yields. Even with the low prices there may be a little profit.
Soybeans-Of course the RBSB remains the hot topic and has persisted until harvest in most fields. They have definitely changed soybean scouting for me. We used to back away a little at about R6.5 but not anymore. Harvest has begun but has been slowed by the lack of sunshine to bring the moisture down. I’ve seen several farms with combines sitting in the fields since the end of last week hoping every day it will drop another percent or two so they can get on with their harvest. Unfortunately, it appears they’ll be sitting there at the end of this week. This could be another year that the seed quality fungicide application pays off. Dr. Trent Irby has some plots in my area this year and it will be interesting to see the results.
Cotton – It seems that every cotton growing season has its ups and downs, and this one has been no different. Regardless of planting date, I think every field had more shed than we like during the month of August. Until that point, it seemed that most fields had a tremendous fruit load and this contributed to the excessive shed in some. The cotton planted from the middle to the end of May seems to have been affected the most due to the delay in maturity the fruit shed caused. In this age cotton we went from maturing on time to hoping for a hot September to mature bolls that are currently newly pollinated blooms. We are still treating a few fields for plantbugs and/or bollworms to protect this fruit. Overall, I feel we have a very good cotton crop but the insect control costs are a little higher than we like to see due to the high bollworm pressure and the extended growing season. Hopefully the rainfall won’t be excessive from the remnants of Harvey and we can move on into defoliation season without much loss due to weather.

Reporting from the North Delta, Joe Townsend, Coahoma
8/30/2017 – Cotton – We are starting to see open cotton on the early planted and still spraying plant bugs on the late planted crops. Overall the potential looks good.
Beans – Early beans are being cut with great yield reports so far. We are finding spray level red shouldered stink bugs in most of our bean fields now. They seem to be higher in numbers the further south you go. We have found them at spray levels in R6.5-7 beans. The looper numbers jumped last week again and we have sprayed for them in combination with sprays for the RSSB.
Corn – Most corn is off or just about off. Great yield reports.
We are under a flash flood watch from Wednesday 10am for the following 3 days from Harvey. Fingers crossed that doesn’t mess up the bean and corn harvest too much!

Mixing Soybean Desiccants with Insecticides

By Angus Catchot, Extension Entomologist, Jeff Gore, Research and Extension Entomologist, Don Cook, Research Entomologist and Trent Irby, Extension Soybean Specialist

This article from the Mississippi Crop Situation blog, August 22, 2017

Over the last few weeks there have been many questions about the legality of mixing insecticides with desiccants applied to soybean. There are several desiccants approved for soybean including Gramoxone, sodium chlorate, Aim 2EC, and Sharpen. There are no issues when mixing insecticides with Gramoxone, Aim 2EC, or Sharpen that we are aware of and the label does not prohibit mixing any insecticide with those products. However, a common practice in MS is to mix Gramoxone with sodium chlorate. The sodium chlorate label specifically says “This product should not be mixed with insecticides or other organic materials, unless specifically recommended, because a fire or explosion may occur”
While safety is the number one concern, according to the formulation specialist at Drexel, the only potential issues with fire or explosion hazards when mixing insecticides with sodium chlorate specifically refers to the mixing with organophosphate insecticides. They have indicated there are no concerns when mixing with pyrethroid, neonicotinoid insecticides, or combinations of the two. Additionally, the Mississippi Bureau of Plant Industry has interpreted the label wording of “unless specifically recommended” as a legal recommendation in situations where insecticides are deemed necessary by practitioners such as Mississippi State University Specialists, as long as they are not in the organophosphate class.
With recent outbreaks of Redbanded stink bug in Mississippi and their ability to cause damage to soybean very late in the season, it is necessary to provide control measures commonly as late as desiccation timing. In situations where this occurs, it would be deemed a common and economically sound practice to mix certain insecticides with desiccants including sodium chlorate.

8/24/2017 – Cotton has been kind of quiet this week. Most fields are still wet but most have missed rains for the last couple of days. Thunderstorms passed through last night and dumped from .5″ to 1.75″ on lots of areas but most cotton missed it. Older cotton is beginning to crack and we don’t need any more rain. Latest cotton is in 3rd week of bloom and looks pretty good. Late cotton will be our best cotton if we could get to some kind of normal conditions.
Peanuts are from 90 dap to 128. I will blast peanuts Saturday to see when growers need to start digging. Most peanut fields were sprayed for lep complex this week. Late leaf spot seems to be getting worse every week in fields that were in poor rotation or growers just couldn’t spray timely. Some of these fields need another week and some of them need 40 days. Southern blight is far and few between. Peanut crop looks really good, just need good conditions from here on out.
Soybeans are from R2 -need to be combined. Aerial web blight has blown up everywhere this week and we are treating most acres. Worms are bad in spots and not in others. RBSB are isolated as well. Still have a big population in most peanut fields. Even where they border soybeans that have pods on them they seem to be staying in peanuts.
Corn harvest has started in places with yields good where timely harvest could occur. Where corn has been ready for a month it was fair. Too much rain damaged a lot in earliest planted corn.

Reporting from the North Delta, Justin George, Merigold
8/25/2017 – Rice: harvest has commenced, very good yields thus far – mostly drained except for some very late June 13th rice. Leaf Blast and paraquat “Disease” in late rice.
Corn: very good corn yields. Working ground, have not burned stalks, disking in stubble.
Soybean: just beginning to cut some dry land and pivot edges. Applying harvest aid alone on early beans; some will get RBSB application though. It’s easy to find threshold numbers. May 7th and later planted beans are getting looper and stinkbug treatment now. June beans are frustrating growers as multiple spray trips just weren’t in their thoughts at planting. Far from being through with late beans

Reporting from the South Delta, Josh Westling, Flora
8/25/2017 – Cotton- Most cotton is NAWF 5 to cut out. Still have some acres with a ways to go. Major fruit shed has been a problem the past few weeks with rains and cloudy weather. Target Spot can be found in most every field with some fields being worse than others. Plant bugs have exploded in some areas in the past week and are being treated. With all the fruit shed taken in to affect, it still looks like a good crop.
Soybeans- Anywhere from R3 to ready to be desiccated. Applying acephate to most fields that are being desiccated for stink bugs. In the younger beans loopers are being treated. Most fields between R5 and R6 are being treated for stink bugs. Soybeans that have been harvested have had great yields.
Corn- Most corn in my area is ready to be harvested or harvested with excellent yields.

Reporting from the North Delta, Bob Stonestreet, Clarksdale
8/25/2017– Cotton: This is a year I can’t wait to end; replanted 80% of April cotton from excessive rainfall and replanted half of that again from sandblast; bollworms, disease, too much rain or too little rain; plant bugs light to moderate early season and now picking up pretty consistently; another bollworm flight started again late last week; populations vary from very light to 20-30% egg lays; working consultants to death; cotton ranges from opening bolls to 6 NAWF; three weeks ago, crop looked great but with shed and target leaf spot, not so sure; two to three more weeks of this before we’re done; thinking of a new career as a Walmart Greeter!
Soybean range from R4 to ready for harvest aid; pod worms really coming after the late beans plus loopers beginning to get in on the act; redbanded stinkbugs picking up as far north as Desoto county (1-2 per 25 sweeps); have treated a few acres early this week in Coahoma county with counts from 4-8 per 25 sweeps.

8/21/2017 – Some cotton has matured to being within a few weeks of defoliation and some will see a frost before it matures. Seeing both stink bug and plant bug numbers up and continuing treatments. Early cotton looks good and some of this later cotton
looks horrible with target spot and a tremendous leaf and fruit drop. Most fields have been treated once or twice with the new chemistries for bollworm with acceptable control.
Some soybeans are receiving harvest aids while some others are not even podding yet. We are still applying fungicides with rust in mind as this next round of insect treatments are being recommended. Soybean looper is now in the mix along with bean leaf beetles and red banded stink bug. Some tremendous numbers of stink bugs in the older beans.

Reporting from Northeast Mississippi, Homer Wilson, Fulton
8/21/2017 – We can’t complain about lack of rain in August this year. Our whole area has had ample rain this month. We are drying out some since the 17th – no boll rot yet but cotton is shedding heavy from stuck blooms and overloads due to lack of sunlight. Our older cotton is cutting out and we are starting to drop fields .We had a moth flight 3 weeks ago and sprayed about 80% of our acres. Most of our cotton is Widestrike with only 60a Widestrike 3. Today we found an increased egg lay in some young cotton that is lush and green (9-20%) and will spray that tomorrow. The plants are loaded and the crop looks good but needs some good sun.
Soybeans: we will dry down a sizeable acreage of early beans this week – most of the leaves are already off. Early beans look good and we have had very few insects .We are starting to find some stinkbugs in wheat beans and a variety of moths but no spraying yet.
We have corn ready to shell if the humidity will drop some. The moisture is a bit high and there is only one farm with a dryer. Most of our corn is dry land but looks super.

Reporting from South Mississippi, Trey Bullock, Hattiesburg
8/21/2017 – Last week I made a comment about bollworm moths not being flushed – well, I take it back after today. Moths were alive and well today and seems to be more than I’ve seen all year. Older cotton may squeak by these but lots of late May to mid-June cotton still to look at. Seeing RBSB in cotton fields that border peanuts. They don’t seem to go very far in cotton but are feeding on bolls. Seeing lots of leaf footed bugs around borders of older cotton as well. Rains are still popping up every afternoon and they didn’t let us down today.
Peanuts are receiving treatments for worms and fungicide where we can get in the field.
Soybeans are being treated for worms and fungicide. Aerial web blight has jumped on beans from R1 to R6 in the past week. Helicopter became available today and they are treating as fast as they can. Showers are complicating applications but hopefully in the next few days we will get treatments out on most of these fields. Loopers and VBC are being treated as well. RBSB are being treated in a few of the fields, some for second time. Most of the fields I treated 2 weeks ago zeroed for the most part and have not had to retreat.
Corn is still mostly in the field waiting to be harvested. All attempts so far have resulted in combines bogged down.

Reporting from the South Delta, Jeff North, Madison
8/22/2017 – Cotton is still pushing in most areas. Has a long way to go in a lot of fields. Some fields still receiving late worm applications with egg numbers increasing. Plant bug nymphs coming to the top and applications are being made to keep a “switch” out of the top. Heat and sunshine is needed now to finish maturing this crop.
Soybeans main issue is RBSB. Applications earlier held for about 3 weeks. Re-infestation beginning again and treatments are being made when 1-2 per 25 sweeps are collected. Many fields may receive an application with the desiccant if numbers warrant. This is a dangerous pest!!
Corn is in full harvest with phenomenal yields being reported.

8/18/2017 – Cotton – My cotton ranges from 6 NAWF to starting to open. I have cut out some fields but, I’m still finding eggs in fields that have a lush terminal. Plant bugs remain light overall and spider mites are in check for now. The biggest problem for me is the excessive boll shed from the weather over the last two weeks and from target spot. I’ll be checking some of my cotton until about the 15th of September.
Soybeans – My soybeans range from r5.3 to harvest aids being applied. We would have desiccated a large portion of our fields last week and this week if not for the weather. We have treated or are about to treat for RBSB everywhere. Loopers are starting to build in several later fields and many will receive treatment over the next few days. Our oldest soybeans are not the bumper crop it was just 14 days ago due to the weather.
Corn – Corn is being harvested between rains in s few places and the yield is GREAT. If we get it all out it will be the best some of my growers have ever had.

Reporting from South Mississippi, Trey Bullock, Hattiesburg
8/17/2017 – Scattered thunderstorms still caused problems most of the week. Today was the first day without rain. We’ve had lots of wash offs and some fields just entirely too wet to spray. Plant bugs have exploded in places and treatments are going out where possible. Bollworm moths seemed to have slowed down this week. Still flushing a few but nothing like last week or beginning of this week. Most of this cotton got treated last week for bollworms with really good results on some and less than desirable on others. Boll rot as well as target spot is really bad in older cotton.
Peanuts are being treated for VBC and loopers. I’ve never seen the numbers of leps in peanuts like I am seeing this week. They have really hit peanuts hard and moths are being flushed in extremely high numbers. All fields that were receiving fungicides this week were treated for worms. Most fields that aren’t getting fungicides are getting treated for leps.
Late soybeans on the west side of my area are being pounded by bollworms and loopers. Treatments have been made and hopefully they will give us a break. These beans have been treated twice and they are at full bloom today. Aerial web blight is showing up in lots of fields and growers are still having trouble getting treatments out.
Corn harvest has started but most got rained out the day they got started.

Trent LaMastus sent these photos of Redbanded Stink Bug immature, cotton boll shed from target spot and evidence of continued egg lay in cotton.

8/13/2017 – Too much rain is the story for the last week here. Accumulated amounts ranging from 6-15 inches have been recorded and it’s still ongoing. In cotton, insect pressure has been light since the big bollworm flare-up we all experienced 3 weeks ago but the last week we’ve been flushing quite a few bollworm moths along with a lot of looper moths. Fresh bollworm eggs are easy to find now along with light plant bug numbers and lingering spider mites. Stink bugs are on the move also. We’ve been spraying pyrethroids plus Acephate plus heavy rates of pix the last three days to hold growth and insects back but numerous applications are not getting the dry time we would like but it’s still better that waiting.
Red Banded Stink Bugs in the youngest soybeans are well above threshold in a very wide area and are being treated with pyrethroids plus Acephate as weather allows. The youngest beans will require close watch for a while yet I’m afraid.
Corn yields reported so far are as good as it gets but everyone is on hold waiting for favorable weather. It appears we have a very good crop all around if the rain will let up.

Reporting from South Mississippi, Trey Bullock, Hattiesburg
8/14/2017 – Cotton is from 2nd week of bloom to open boll. Rains have continued to cause lots of problems in cotton. Plants are having trouble sticking fruit with rains every day. We basically were rain free Saturday and Sunday for the most part. Bollworms are still persisting with some fields getting treatments and some just too wet too run. These fields that are still too wet got about 1.5″ this evening so we are out a few more days. Plant bugs are still relatively low. Whiteflies are becoming easier to find but nothing at treatable levels. Hope they stay that way.
Peanuts are from 70 to 120 dap. Still trying to stay on top of late leaf spot. This is very challenging due to wet fields and rains. We’ve done surprisingly well under these conditions. We just need to be able to get back in soon. Worms of all flavors are in the peanuts with some really eating lots of foliage. Treatments are going out with fungicides with some fields strictly getting treated for worms. VBC and loopers are the primary leps and VBC moths are thick in the fields. Grass is becoming a big problem as well.
Soybeans are from R2 -R7. Aerial web blight is becoming more prevalent as beans lap up. Again, having trouble getting treatments out due to rain. Insects are really picking up across the board. VBC and loopers have really picked up this week. Most older beans have had one treatment for RBSB.
Corn is just sitting in the field. Hopefully rains will give growers a window to get it out.

There have been numerous questions around the potential damage severity of Redbanded stink bug in soybean in Arkansas and Mississippi. We have had well over 150 calls this week alone on insecticide efficacy, thresholds, and insecticide termination. With any new pest that has such high damage potential and changes traditional management considerations, naturally there are lots of questions being asked from areas of Mississippi and Arkansas where this pest has not commonly occurred.
Due to the potential severity of this pest, and the large number of acres being treated and lined up to be treated, we are hosting an ArkLaMiss Emergency Forum on Redbanded stink bug, Thursday, August 17 at the Capps Center in Stoneville at 2:00 p.m. The goal of the meeting is to share and provide all the current data associated with RBSB and hear from academics and consultants in LA who have learned to manage this pest successfully over the years where it routinely occurs.
• University researchers, extension, and consultants from Louisiana, Arkansas, and Mississippi will be sharing data and experiences managing Redbanded stink bug in soybean
• Data on damage potential, yield loss, insecticide performance, thresholds, and insecticide termination will be shared by group
• Meeting will be streamed and recorded for those who cannot be in attendance
• Meeting is free and open to all who have questions on management of Redbanded stink bug in Mid-South soybeans
• More information will be coming out on Monday on Tuesday about the meeting details and how to live stream the feed
We hope to have as many stakeholders present from the ArkLaMiss area as possible. Feel free to share this information with anyone interested in learning the latest management strategies for RBSB

Consultant Commentary – Up-to-Date Information from Mississippi’s Crop Professionals

Reporting from the South Delta, Lauren Green, Greenwood
8/9/2017 – Cotton is from 2NAWF to 7NAWF. We have gotten anywhere from 1″ up to 4.5″ of rain over last couple of days. Plant bug numbers have not been out of control but are treating while going after spider mites and worms. Eggs are picking back up this week in certain areas.
Corn is done and had started harvest before rain. It seems to be an above average crop so far.
Most soybeans are anywhere from R4 to R7. Early planted soybeans that are R6-R7 have had increase in stinkbug numbers over last two weeks and fair amount have been treated for red banded stinkbugs. All late planted soybeans were treated for pod
worms and are still holding.

Reporting from East Mississippi, Bert Falkner, West Point
8/10/2017 – Corn is at black layer growth stage. A little has been harvested but I’ve not heard any yields.
Soybeans are R2/R3 – to mostly R5.5/R6 growth stage. We’ve treated a few fields with a mixture of stink bugs including red banded stink bug. The worm complex really increased ion R2/R3 beans. Treated a few fields and will treat more when weather breaks and add a fungicide. A few of the oldest beans are starting to turn.
Had a little flare up of worms in peanuts – not at treatable levels, but close. Started seeing low levels of soil type disease late last week, 7 to 10 days after fungicides with leaf spot in the mix. Fungicides never had a good rain to get them activated.
Young cotton 6-8 NAWF – older cotton 2-5 NAWF with a few fields a little further along. We are probably 10-14 days later than normal mostly because of the early June rains. Have treated very few fields for plant bugs this week and they remain low. Stink bugs are moving into cotton and we’ve treated a few fields. Also treating spider mites in hot spots and still treating some Bt cotton, however, eggs/worms/moth numbers are down this week. Adding Pix into all insecticide applications. Some of this cotton has a long way to go. Today this crop is just a good average crop. Cotton made a lot of positive changes in the last 14 days. My area has received 1.5” – 7.5” of rain since Monday. Very concerned about wet cloudy conditions.

Reporting from South Mississippi, Trey Bullock, Hattiesburg
8/10/2017 – Most of my area has had 9-12 inches since last Sunday. Cotton is from 1st week of bloom to cutout and 24 nodes. Boll rot is not horrible but it’s headed that way. Target spot has blown up in older cotton and defoliating lots of bottom leaves. Not sure this will be all bad. Bollworms are still being sprayed and seemed to have increased in the last 10 days the further south I go. Plant bugs have picked up a little in the last 5 days as well as nymphs. Silverwing Whiteflies are picking up in one county I work. Lots of watermelons in this county and I think they may be coming out of those fields. Hope they don’t get too bad as product is hard to find I believe.
Young soybeans are full of bollworms and loopers. Velvetbean caterpillars are really picking up this week as well. Stink bugs are kind of scattered around but not too bad.
Lots of small loopers and velvetbeans in peanuts today. Shaking 9-10 worms per foot in most fields. We seem to have gotten late leaf spot under control. Only problem now is fields are flooded and growers can’t get back in fields in a timely manner. Peanut crop really looks good. Harvest should start in the next 3 weeks.

Reporting from East Mississippi, Phillip McKibben, Maben
8/10/2017 – Corn – we’re field-drying now, hoping to fire up the combines ASAP. Moisture is running mid to upper 20’s right now in most.
Soybeans – RBSB have been very spotty; practically no issues where we applied insecticides with fungicides at early R4 (interestingly). Sprays have been effective where we’ve had to take them out.
Cotton – everything has been spotty. Mites have been heavy in spots, mainly around edges, but we’ve had to take them out in a couple of fields. We’re finally seeing a lull in bollworm numbers and the egg-lay has also tapered off. We ended up treating a little over half of our acres for worms; both Widestrike and BG2 equally.
Sweetpotatoes – we hope to begin harvest the middle of next week, but will primarily be digging foundation seed. Main harvest should begin Labor Day week. We’re looking at a phenomenal crop, but the recent rains have brought back some PTSD-like flashbacks from 2009. Worm complex sprays have been necessary in some locations, not in others. Overall we’ve had a much easier time dealing with insects this year compared to last… so far; we still have 70 days left to manage a big chunk of this crop.
