“We’ve also desiccated about 4,000 acres of soybeans that’ll be ready to harvest in a week. We are spraying the R-5/R-6 soybeans for a mix of stink bugs in Concordia Parish. That includes redbanded stink bugs. Applications for corn earworms have been going out on younger beans.
“Hurricane Barry damaged a substantial number of acres of soybeans. Our rivers – the Mississippi, Black and Red – are high now and that water can’t recede. We already had acres that couldn’t be planted due to the water, and now another 3,000 to 4,000 sustained damage from the hurricane.”
Andy Graves, Graves Agronomy Service, Clarksdale, Mississippi:
“Our cotton ranges from fields that only began blooming 2 weeks ago to older cotton at 4 nodes above white flower. We began irrigating today (7/29), even though there’s a chance of rain.
“Plant bugs have been light for several weeks. Aphids have been spotty and we’re finding a lot of fungus, so we’re letting Mother Nature do her job.
“We began picking up a bollworm flight about 12 days ago. The egg lay has been intermittent, with more substantial numbers in the older cotton. Last week, we found worms running 4% to 20% far down in the canopy. So, we’re making Prevathon and Besiege applications and adding Zeal for spider mites.
“I picked up bacterial blight yesterday. Target spot is present, too, but the crop should be able to outrun it. Johnsongrass and barnyardgrass have been challenging to control.
“A few bollworms are present in our younger soybeans, although we see plenty of moths. I’ve picked up several redbanded stink bugs in my sweeps – but those were in cotton. That’s alarming, considering what’s been applied on cotton so far. Last year’s extremely mild winter may bite us because we have some very late soybeans.”
Gus Lorenz, Arkansas Extension IPM Specialist:
“The plant bug battle has heated up, and plant bugs continue riding into many fields in south and northeast Arkansas. You’ll spray but then plant bugs are back in 5 to 7 days.
“Aphid numbers ticked up in the northeast corner of the state. Mainly, I’m advising people to wait until plant bugs hit treatment levels and then use something like Transform to control both.
“Bollworms are hitting cotton from Marianna south to the Louisiana line. A tremendous egg lay occurred in the last 4 or 5 days, and Prevathon or Besiege went out. It’s rather interesting that we’re not catching as many moths in traps as expected. We’re certainly kicking them up in the fields, though.
“It appears that the late soybeans will be a costly crop to bring to harvest. The flight of bollworms in western Arkansas continues, with numbers increasing. That trend is now beginning in the Delta region. Some virus is being applied but diamides are going out, too.
“High numbers of brown and green stink bug and egg mass numbers remain. Redbanded stink bugs (RBSB) are also rising up, particularly in the southern half of the state. We’re finding immatures all the way up to Stuttgart. Be vigilant and scout hard for them. I predict that treatments for RBSB will start in the next several weeks.
“Also, looper numbers are building due to Hurricane Barry blowing them north.
“Calls continue about sugarcane aphids in grain sorghum. Those are dogging the crop and treatments have gone out on about every acre.”
Blake Foust, Consultant, Southern Heritage Cotton, LLC, Forrest City, Arkansas:
“This has not been a fun growing season, and everyone seems eager to see this one behind us. Much of our cotton planted on time is at cutout, and it looks good. We may water some older cotton next week, and that should finish that part of the crop. The replanted cotton is up and down.
“We’re standing on the cotton hard with Pix, and that’s been the story for the last month.
“We’ve sprayed only four cotton fields for bollworms and haven’t seen many in soybeans, either. Plant bugs fired up in the last several days, and I expect to be hitting them hard over the next several weeks.
“It has been a challenge, but crops appear to be doing good on well-drained ground. The wet weather means we haven’t had a lot of days to get work done on time.
“The milo is headed and looks fine. We’ve had to deal with green stink bugs in later R-5 soybeans. Peanuts look as good as they have in the last 3 or 4 years. They lapped early, probably because of the rain. But we’ve also dealt with weed issues in peanuts due to the rains and when we could apply herbicides.”
Scott Stewart, Extension Entomologist, Jackson, Tennessee:
“We’ve had decent rainfall and crops seem fine, aside from drier spots in middle and eastern Tennessee. Cotton has good to excellent potential. Some fields will be at cutout plus 350 DD 60s next week – 5 nodes above white flower. So, that portion is out of the woods insect-wise.
“The bollworm moth flight has yet to show. A couple of people reported light egg lays along the Mississippi line. Lack of moths or eggs has been a point of conversation among people in the field, and we’re running at least a week behind our average flight time.
“Plant bugs and stink bug populations are mostly average, with a few hot places that required applications.
“The corn crop is exceptional, with few problems. Scout early soybeans for stink bugs – greens, browns and brown marmorated. I don’t expect redbanded stink bugs (RBSB) until the end of the season, if at all. It takes RBSB too long to get this far north, although that may change if we have another warm winter.”
Sebe Brown, Louisiana Extension Field Crops Entomologist:
“With all the rain, we have some flooded fields from Alexandria south. Certain areas received 8 inches from Hurricane Barry and another 2.5 inches last weekend. Right now, there’s a deluge and we’ll end up with another 5 or 6 inches. With the rain and rank growth, target spot will likely become a problem. We’ve been through years like this with tremendous rainfall going into August, and that triggered fruit shed.
