“Our soybeans are at R4 and we’ve sprayed a few fields for stink bugs, mostly greens and browns. We worry about redbanded stink bugs but haven’t had to treat them yet. A good many of our soybeans were planted late, and we’ll be on the lookout for bollworms in those fields next week.”
Keith Collins, Extension Agent, Richland, Ouachita and Franklin Parishes, Rayville, Louisiana:
“The storms have rolled through and we’re actually receiving some welcomed sunshine in northeast Louisiana. Barry gave us 2 to 3 inches of rain and it was a slow, soaking event. I understand that other areas in this part of the state did receive heavier amounts, from 6 to 7 inches.
“A large percentage of our cotton is now setting bolls and Pix management is the focus. We’d started irrigating cotton last week, so these latest rains hit us just right.
“We’ve treated on a wider basis for aphids than in the past several years and are running into plant bug issues as cotton reaches the second or third week of bloom. Bollworm trap counts have been low for this time of year, but we expect them to pick up as corn begins drying down.
“Rains hit our soybeans at a good time and they seem to be podding up well. We have beans planted all the way to the first week of July. After such a mild winter, everyone was expecting heavy redbanded stink bug numbers but I’ve only caught 2 all season. Around R5 is when they normally show up in northeast Louisiana and we’re not there yet.”
Dennis Reginelli, Area Extension Agent and Agronomist (Retired), East-Central Mississippi:
“Rainfall total from Barry ranged from 1 to 6 inches. Hopefully, all the rain won’t trigger much fruit shed in the cotton. We are fighting plant bugs and aphids in places. Folks are also applying plant growth regulators to hold growth in check.”
Phillip McKibben, McKibben Ag Services, Mathiston, Mississippi:
“We’re just starting to dry out from Barry. Obviously, our dryland crops now have plenty of moisture. We knew the rains were coming so we made last-minute Pix applications in fields where it had been 10 days or longer since the last application. We also made preventive treatments for plant bugs where we knew we couldn’t get in the field again for a week.
“Our cotton looks good and most is in the second week of bloom, with our oldest in the fourth week. We haven’t seen bollworm moths yet. Last week, we flushed a moth – literally a single moth all week.
“We’ve been able to keep weeds under control in cotton and are still touching up late-planted soybeans. It’s been a challenge with all the rain.
“We also work sweet potatoes. Roundup drift turned up earlier in the year and we are still monitoring it closely and are attempting to track recovery through hyperspectral imagery. This week, dicamba drift injury appeared on almost 2,000 acres of sweet potatoes, and some of it looks serious. We need the auxin technology, but it is difficult to coordinate the planting of all of the crops and still maintain good relationships with our neighbors. And good relationships are so important going into the future.
“Our corn is well into dent. We haven’t had to water corn much this year and yield potential looks good.
“We picked up some redbanded stink bugs last week. That’s about when they first showed up 4 years ago. We don’t foresee a big problem with them this year.”
Sebe Brown, Louisiana Extension Field Crops Entomologist:
“Soils are saturated across much of Louisiana. Areas from Alexandria south received at least a foot of rain. In central Louisiana, about 7 inches have fallen (as of 7/16) and it’s still coming down. A few fields went under water and it’ll take a while for them to drain off.
“With the cloudy weather and the sheer amount of rainfall, fruit is shedding. We’re still fighting plant bugs. Bollworm egg laying has been very slow and the expected numbers haven’t materialized, at least not yet.
“In soybeans, redbanded stink bugs are still hanging around and growers are spraying all over the state. Numbers aren’t huge because no one is allowing them to get above threshold.”
Gary Wolfe, La-Ark Agricultural Consulting, Ida, Louisiana:
“Our cotton is quiet right now. Plant bug and moth activity have been slow. We are making plant bug applications and are adding pyrethroids. We missed the rains from Barry and, in fact, actually need rain here in northwest Louisiana.
“The cotton crop is incredibly strung out in terms of planting dates. Maybe 25% looks great, 50% looks average and 25% is poor. As far as weeds go, our fields are clean. I’m sure wondering how this late crop will turn out on the back end.”
Scott Stewart, Extension Entomologist, Jackson, Tennessee:
“It’s rained a good deal in West Tennessee, from 1 inch to 5 inches with some flooding, and that’s hampered field work. Plant bugs appear to be rather light. Adults are moving into cotton but that’s happening late. I suspect this is due to wet weather keeping wild hosts green enough to hold populations longer.
“The bollworm moth flight hasn’t kicked off yet and counts were very low last week.
“We’re beginning to hear reports of target spot. That’s to be expected after 4 or 5 days of cloudy weather. I expect there will be some spraying for that. Look for it in tight, closed canopies.”
Angus Catchot, Mississippi Extension Entomologist:
“Aphids are still present in some of our cotton, although populations are crashing in a few areas. In my aphid trials, numbers are falling off hard in places, and rains across the state may have helped speed that along.
