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

Reporting from the South Delta, Andy Tonos, Greenville
7/20/2017 – Corn is mostly done but irrigating some of the later corn.
Soybean weed control is complete except with a few late planted fields. My focus now is on insects and irrigation. Bollworms are in the majority of all young beans and also Redbanded stink bugs have been present along with greens and browns in older beans that are filling pods.
In rice, we are applying pyrethroids on the oldest and fungicides on some other, with a few late fields just now getting the second mid-season shot of fertilizer.
In cotton, we are applying insecticides and Pix most every week for a complex of pests. I’m finding some bollworms in spots as most everyone is. It’s definitely gotten tricky.

7/20/2017 -Cotton is from 12 nodes to 22 nodes. Older cotton on the Miss. river side of my area is running 3-6 NAWF. Most of that cotton was treated for bollworms last week. Hattiesburg area is starting to dry out a little. Plant growth regulators and Roundup have gone out in fields where sprayers could stand up. Some treatments for aphids still going out. Spider mites (red) are showing up in some fields. Some at treatable levels but very light in most.
Peanuts are from 30 dap to 95 dap. Some fields are way behind on fungicide apps and late leaf spot is showing up in a few fields with poor rotation. Most of these fields are still too wet to spray but if we don’t get any rain tomorrow sprayers can probably stand up Saturday. Bollworms are heavy in a few fields and will be treated this week.
Young soybeans behind flood waters are being treated for bollworms, FAW, and granulated cutworms. Older beans are relatively clean so far this week. Treated one farm for red bands stink bugs today.
Corn is from roasting ear to black layer. Older corn looks pretty good. Later corn looks better or seems to have more potential to me at this point.

7/20/2017 – We’re struggling to get crops irrigated in a timely fashion.
Soybeans – April 5th-15th planted beans are at R6 and although stinkbugs are not a problem yet, numbers are getting higher every week, even redbanded SB. In March 20th-23rd planted beans, at R7, redbanded and other stink bugs are being treated. May planted beans at R3 are being treated with Prevathon or Intrepid-Edge for bollworm.
Cotton – Bollworms are surviving in BollGard cotton. Bollworm moths moved in around July 1 but no treatments were made until the 11th – 5-7 days late. We’ve treated 75% of cotton acres with either Prevathon or Besiege adding ¾lb/a of acephate if plant bugs were present; ¾ oz/a. of Transform if aphids were present or 3 oz/a AI of Abi-mek if spider mites were present.

7/20.2017 – Bollworm pressure has been heavy in places. We saw the moths and knew what was coming. Anticipate and treat ahead of the hatch. We knew what was coming but hoped Bt would handle it. Take nothing for granted! “When in doubt put it out!!

Reporting from the North Delta, Charlie Craig, Clarksdale
7/20/2017 – Plant bugs light at present, beginning to pick up worms and eggs. Jury still out on what this will amount to and treating spider mites in spots.

Reporting from the South Delta, Haley Easley, Greenwood
7/20/2017 – Bollworm pressure is widespread and heavy – seems like every crop with a bloom has them. Not sure what we getting out of Bt anymore. I have some conventional cotton that has less boll damage than Bt due to being more aggressive on spraying bollworms. I guess we have to treat Bt cotton like its conventional now. Plant bugs have been steady but under control. Main pest today is bollworms. Bacterial blight is bad in some varieties. Not much on the fruit yet but I can’t see how it won’t be.
Target spot showing up in beans but not severe as last year. Spraying isolated fields for red banded stink bugs. Seems like they are only in beans R6 or later for now.
Peanuts look good and diseases low for now. Worms getting close to threshold in peanuts. Will clean up on next fungicide app. Irrigating a lot this week but first time on a lot of fields. Rain makes grain. Corn and beans look very good. Cotton so-so.

7/20/2017 – Rainfall has been very timely up to this point. Other than corn, all other crops potential will be determined, to a large degree, on favorable growing and harvesting conditions from here on out.
Corn is at full dent and a few fields are approaching black layer. This could possibly be our highest yielding corn crop ever if we are able to get it out of the field.
Soybeans….our crop varies greatly in maturity ranging from R1 to R6. Some growers elected to apply fungicides this year but many did not. Disease pressure has been extremely light up to this point but could change from here on out. Bollworm pressure in late soybeans has increased this week with many fields being treated and many others on the edge of reaching threshold. The diamides have been the chemistry of choice to address this problem. There seems to be more bollworm pressure in drill soybeans than row beans but this may be purely coincidental. I would like to know what other consultants see regarding this. Pyrethroids and acephate are only being used to control the stink bug complex and thus far not many fields have been treated. I do expect this to change.
Cotton….overall our crop is pretty late. Fruit set has been good but plant growth regulators are being used heavily and repeatedly. The main concern at this time regarding insects is the bollworm pressure in heavy fruiting cotton. It’s very simple. If you are in peak bloom you have heavy pressure. Our best control options are to monitor the bloom and when moths are noted in heavy numbers and the egg lay is increasing go ahead and apply Besiege or Prevathon and let them hatch into it. Then monitor for more eggs and larvae and do it again in 2 to 3 weeks. Waiting to see surviving larvae will get us in trouble. Hindsight is 20-20 but this is the approach for now that seems to be working best and even following this protocol, there will be escapes. Growers may be reluctant to adopt this strategy but these are steps that have to be taken to protect this crop. Just like air in the tires and fuel in the tank of a truck, it takes certain steps to make it go, so go the steps for cotton production as well.

7/21/2017 – Corn-We’re expecting to see some combines hit the fields very soon and are anxiously waiting.
Soybeans-Most are close to or have reached R6 now and still look good even though this heat is pulling the moisture out of the ground fast. Irrigation has begun as have some insecticide applications. Red Banded Stink Bugs are hitting threshold in some fields of early soybeans and corn earworms are hitting the late planted soybeans that are R3-4. We’ve made insecticide applications on limited acres for each but expect more to follow.
Cotton-The cotton crop is progressing at a normal pace but still has a long way to go. We have had a very light tarnished plant bug year so far but things are getting active with other pests. Bollworm moths have been flushing from the fields for quite some time and left plenty of eggs. We are battling surviving larva in most fields now with mostly good results but a scare here and there, too. Beginning to see a few spider mites but not anything like the last few years. Irrigation has begun here too, whether needed or not.

7/21/2017 – It’s hot and dry in our area. After the June rains, our moisture has been scarce. We seem to be in a pocket between the rain. The recent heat has moved cotton up some but we are still about 10 days behind, based on planting date. Most of our crop will reach peak bloom about the 26th. Insects have been quite for the most part. We had a flurry of plant bugs early but aphids have been more prevalent, even after Transform, they came back. Fungus is present now and if we could get a rain, cotton would clean off. We have a ways to go with this crop and it needs water now.
Most of our pivots were on corn, which looks super, with the majority starting to show brown shucks.
Early beans are mostly R5 plus and need water. Insects haven’t been high – a few army worms and spotty bollworms but more stink bugs – mostly brown – are showing up and we are close to pulling the trigger. Our wheat beans are 3-5 trifolates and fairly clean. No real problems have developed.
