“Corn harvest started in Noxubee County. Soybeans at the south end of my area are at R-5 to R-6.5. In the north end, fields are at R-1. I’m beginning to find a few redbanded stink bugs and loopers but nothing at threshold. Maybe the older beans will outrun insects and diseases.
“In peanuts, we put out fungicides before Barry came through and will come back with another treatment this week. A bit of southern blight is all we’ve seen.”
Herbert Jones Jr., Ind. Consultant, Leland, Mississippi:
“Showers over the weekend in Bolivar and Washington Counties were welcome, but we’re still irrigating most fields. Plant bug numbers haven’t increased since the last treatment at the start of August.
“Since early August, bollworm populations haven’t warranted control. I just wrote a report with eggs running 4% to 6%. Plant bugs are also at the same percentages. About 20% to 30% of the cotton is cutting out. The bad thing is that I also have some cotton in the first week of bloom.
“Most corn is still running high moisture. The fields cut so far had irregular stands, so we’re still unsure about yields.
“In soybeans, we have three different plantings. The first is about ready to combine and has no insect problems. We had to spray the second planting several weeks ago for worms. The last planting is just beginning to bloom, with no worm sprays needed yet.
“Stink bugs haven’t shown up in the numbers expected for either cotton or soybeans. Despite a lot of sweeping and shake-sheet counts, I have yet to see the first redbanded.”
Hank Jones, RHJ Ag Services, Winnsboro, Louisiana:
“Even with this year’s rocky start, cotton has rebounded in the last 2 weeks, and I’m more optimistic. With this year’s rains, we haven’t watered several fields that generally require 3 or 4 irrigations.
“The early cotton is less than 4 nodes above white flower, and the last irrigations is under way. We’re trying to wrap up that portion of the crop, and high temperatures this week should force the plants to bloom out the top.
“Plant bug numbers haven’t been outrageous, and treatments have kept them in check so far.
“Some farmers tiptoed into cutting corn last week. Dryland yields are good at around 180- to 190-bu/acre. On better Macon Ridge soils, we’re averaging 200-plus and still haven’t moved into our best fields.
“In soybeans, we’re in the thick of a redbanded stink bug battle and have treated some very early fields twice. In the last 10 days, we’ve sprayed later beans with a diamide to control bollworms. We’ve also put out Heligen.”
Victor Roth, Roth Farm Service, Malden, Missouri:
“In many fields, cotton is in late bloom or has put on small bolls in the top. Other fields are at mid-bloom. Mostly, we’re 2 to 5 nodes above white flower.
“Rains prevented proper weed control, and that started several months ago. You can see pigweed and grass in some fields, but the main emphasis now is on getting the crop squared away.
“Plant bugs are mostly under control, although spider mite numbers won’t drop off.
“The early corn has finished and is in dry-down mode. The late-planted corn probably needs another 4 to 6 weeks.
“Soybeans range from R-3 to R-5. Some fields received a fungicide. I haven’t seen treatable levels of worms or stink bugs, which is rather amazing. At this point, it usually attracts pests.”
Sebe Brown, Louisiana Extension Field Crops Entomologist:
“Later-planted cotton is running 6 to 8 nodes above white flower, and we’re fighting plant bugs. Since a big part of our cotton is well past cutout, plant bugs are concentrating in the younger fields, so control is harder with the regular insecticide rates.
“To deal with plant bugs, we’re having to get creative with tank mixes – maybe acephate/Transform or go up on use rates. Guys are typically running about 1.25 pounds of acephate or upping Transform to 2 ounces. The plant bugs are increasingly difficult to control as the summer goes on.
“The bollworm egg lay subsided. Now, bollworms are deep in the Bollgard 2 canopy, and control isn’t holding up because the worms are feeding on mature bolls.
“Worms usually run through July. At the end of that period, spray deposition is very good where plants are short and haven’t lapped. But when the crop is large and lapped — even if you do everything right – it’s difficult to get an insecticide into the canopy, and we’re dealing with that now.
“Spider mites are flaring during this hot, dry spell, but they’re localized, and guys are reporting proper control with abamectin.
“Everyone with storage is cutting corn. I’ve heard yields from 160 to 230 bu/acre.
“The stink bug complex has moved into our soybeans and is meeting thresholds throughout the state. Loopers are turning up but aren’t at threshold.”
Scott Stewart, Extension Entomologist, Jackson, Tennessee:
“This week, people are asking a lot of questions about bollworm control. They have lost a bit of enthusiasm because the cotton market has dipped, and they don’t want to spend more money. But the bollworms are forcing their hand in Bollgard 2 cotton. The Bollgard 3 and WideStrike seem to be holding up well.
“We just posted a podcast about some specific recommendations for bollworm control on the UTcrops News Blog (see link in the Also of Note section).
