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

Reporting from the South Delta, Billy Bryant, Greenwood
7/24/2017 – Soybeans – Most acreage, 5.2 or greener, being treated for bollworm infestation with Intrepid Edge or Prevathon. Both products giving exceptional control. Stink bugs infesting older 5.9 beans and being taken out with Bifenthrin + Acephate. About 30 percent of these are RBSB.
Cotton – Have been under bollworm moth flight for 2 weeks. Have mostly been applying Bifenthrin + Acephate – adding Transform where needed for aphids. Control has been good and spacing spray intervals on about 12 days on average. Seeing a consistent slippage of about 2 percent into small bolls under dry tags. Next round of sprays will be Prevathon if pressure persists and the situation is favorable for that. Plant bugs killed out- seeing almost none. Aphids still here but have seen fungal disease on two farms now. No more aphid treatments for me. Pounding with Pix on row watered fields. These most popular varieties we can barely hold when the heat and water comes.
Peanuts – Very little disease activity. My peanuts this year on ground that has been in peanuts before so I am being more timely on fungicide treatments. 3rd app will go out this week. May be adding IntrepidEdge if worm complex continues to increase. Bollworms were about half threshold last week with some baby loopers mixed in. Most are lapped and really making.

7/24/2017 – Cotton- Aphids are pretty much gone. High note
of the week is plantbugs are nowhere to be found. I wish I could say the same for bollworms. Our best control was early at egg lay. When treating day old worms our control is poor to no control at all. However, to end the week I looked behind some Intrepid Edge @ 7 oz. It was only a few hundred acres but I left feeling pretty good about things. I’m cautiously optimistic but I intend on looking at more treated acres.
Soybeans- Beans are V5 to done. Treated some bollworms in R2 beans and RBSB applications are on the increase. Not by choice but because cotton acres increased, we have been checking beans twice a week and it pays off when RBSB are in the mix. Nothing close to treatable numbers but loopers starting to show up too. I hope soybean yields live up to expectations. Looks like a really strong crop.

7/24/2017 – Corn – R5 growth stage, 7-10 days from black layer. After this week should wind up all irrigation in corn – making one last pass this week. Dry land corn is drying down fast with heat and dry weather. Some corn trying to out-run rust but some fields treated. Fungicide treated fields have healthier plants.
Soybeans – Mostly R2 to pushing R6 growth stage. To this point, not a lot of insect pressure but stink bug pressure building in areas. Overall disease pressure has been light until the last 7 days. High percentage of beans have had a fungicide. Balance of fungicides on beans will be lined up in the next 7-10 days. Watering all irrigated beans as hard as we can.
Peanuts – Up to 80 days old. peg numbers look very good. Insects have been light. Soil diseases have been light so far but leaf spot has increased in the last 5-7 days. Starting 2nd fungicide applications on all peanuts this week.
Cotton – Cotton ranges from 10-12 nodes to NAWF 6-9. Treating worms with diamide class insecticides and at times tank mixing for plant bugs. Plant bug numbers have been down in the past 7-10 days. Treating a few spider mites and adding Pix to all insecticides where needed. All irrigated cotton has been watered at least once and will start back again this week. We have a fruiting gap in most of this cotton caused by 14 consecutive days of cloudy weather plus 10 days of rain. These areas had a lot of nitrogen issues and we put out a lot of ammonium sulfate. Growers are not happy about treating worms in Bt cotton. It’s very dry now and we need a rain – scattered showers around this afternoon.

Reporting from South Mississippi, Trey Bullock, Hattiesburg
7/25/2017 – Cotton ranges from 12-21 nodes Aphids are building back up this week. A few fields at treatable levels. Red spider mites are being found consistently in most fields. Plant bug numbers are increasing with some fields are on the books to be sprayed. Still flushing bollworm moths but not as frequently. Found a few eggs yesterday but far and few between. Hattiesburg area had rain all day yesterday with totals up to 2″.
Peanuts are from 60 to 100 dap. Growers got a lot of fields sprayed over the weekend. Lots f fields still wet and yesterday’s rains didn’t help anything out. Still lots of fields that need to be sprayed with fungicides that are already behind and late. Worms of all flavors are present in most fields with a few at treatable levels. Lots of red banded stink bugs in peanuts. Noticed this last year as well.
Corn is from roaring ears to black layer. Oldest corn has turned and beginning to try to dry down. Harvest could start in 2-3 weeks.
Soybeans are from V4-R5.8. Disease is low for the most part. Some fields were treated for red banded the end of last week as well as bollworms.

Reporting from the North Delta, Justin George, Merigold
7/25/2017 – Soybeans: Mostly R5-R6… some wheat beans just blooming though. Most R2-R 4.5 age beans have been sprayed over the last 2 weeks for Bollworms. Watering around, but older dryland beans are burning up now. Lots of four bean pods this year has us looking forward to harvest in older beans.
Rice: Draining a lot next week. Some late rice just going to flood (it will be a race against the frost for these acres). Sprayed most acres for Stinkbugs and Armyworms.
Corn: Finished up irrigation last week. Cobs look great. Looking forward to harvest.
Cotton: Strongly agree with Haley Easley and Jeff North’s comments from last week’s report.
