Lesser cornstalk borers have developed into a bigger problem than usual in parts of Georgia. Connect in our Links section for additional info.

 

Foliage feeders of various kinds are turning up in the lower Southeast. In places, worms are clearly below threshold levels, while in other areas defoliation and/or counts have triggered treatments.

 

In the Southwest peanuts are moving along, thanks to good rains and low disease pressure. Preventive fungicide treatments are going out. Weed control remains part of the focus.

Problems with lesser cornstalk borer (LCB)?
Dimilin® insect growth regulator prevents larvae of pests like LCB from advancing to the next life stage, stopping them before they can damage your peanuts.

Research proves it! Dimilin increases yields for added profit:
Three Dimilin applications offer the most effective control of LCB and have improved peanut yield.
A low-rate, three-spray approach increased yields considerably more than a two-spray regimen.
For best results, apply 4 fl oz/A at 45, 60 & 75 days after plant emergence.

The benefits of Dimilin don't end there:
Easy to apply with standard spray equipment
Broad-spectrum pest control with long-lasting residual activity
Low usage rate of 4 – 8 oz/A
Low per acre cost of application
Low impact on beneficials; ideal in IPM programs
Tank-mix flexibility
More superior grade nuts

CROP REPORTS

Brandon Phillips, Phillips Ag Services, LLC, Douglas, Georgia: “Our peanuts range from 70 days old down to 40. We’re starting to pick up a good many lesser cornstalk borers. Some fields will receive Dimilin shots, some won’t. We’re starting to see a mixed bag of worms – velvetbean caterpillars, loopers, budworms, cutworms and beet armyworms. It’s a wide array, but nothing treatable yet (as of 7/15).

 

“Nothing really stands out as far as disease goes. On drier fields we’re seeing a little aspergillus crown rot, the kind of thing you expect in dry periods. It’s nothing substantial. We’re finding threecornered alfalfa hoppers in places. Some farmers go ahead and include a low rate of a pyrethroid with fungicides for that, based on the number of girdled stems and adult and immature counts I'm reporting. That’s just their standard practice.”

 

Todd Baughman, Oklahoma State University Institute for Agricultural Biosciences, Program Support Leader, Peanuts, Ardmore: “Things are looking really good. Obviously, we’ve gotten hotter and drier and we’re relying more on irrigation. We’re starting to peg, which is the highest water demand period. So the big deal will be to maintain our irrigation.

 

“Weeds continue to be our biggest issue, and a lot of guys have been battling them. Diseases are minimal as a whole. But in this stage of growth we need to keep an eye on potential disease problems. Overall, we’ve got prospects for a really good crop.”

 

Trey Bullock, Bullock's Ag Consulting, Hattiesburg, Mississippi: "The soil-borne/white mold shot is going out on our older peanuts. We’re trying a lot of Apogee plant growth regulator this year. The rain is hemming us up a little where we need to spray. Peanuts look really good, with almost zero disease right now. Funky leaf spot and stuff like that are showing up but nothing major or that we’d worry about a lot. At least 80% of my peanuts are pegging and 20% are putting on pods. A few later fields just started blooming this week.”

 

Chris Locke, CSL Consulting Inc., Sudan, Texas/Eastern New Mexico: “We received anywhere from 2 tenths to an inch of rain this week. We need that to keep going to increase moisture in our profile. It’s down to about 1 to 1.5 feet now.

“Our peanuts are blooming and starting to peg well. With all the rain, nodulation is going great. All Valencias and all Virginias are getting treated with Abound as for rhizoctonia prevention. For Spanish, sometimes we can wait for treatment because they are a lot hardier.”

 

Ron Smith, Alabama Extension Entomologist: “The spider mite situation continues in scattered peanut fields in south Alabama. People are finding the grass-strain fall armyworm in peanuts. In some fields you’ll come across an occasional larvae, but in other locations it’s already taken a significant amount of foliage and is definitely at treatable levels. In Escambia County, Florida, they heavily defoliated peanuts in one field. So it’s a hit-or-miss deal, but in places treatments have been warranted. Different worm species also are scattered around out there – an occasional looper, some yellow striped armyworm and so forth – but they’re not necessarily at damaging levels.”

 

Jack Royal, Royal’s Agricultural Consulting Co., Inc., Leary, Georgia: “I’m seeing a lot of moths but, so far, have not had to spray anything for foliage feeders (as of 7/15). In some dry fields we’re just now seeing lesser cornstalk borers showing up, although south of us people have been fighting worms and lessers.”

 

Ames Herbert, Virginia Extension Entomologist: "In peanuts, we’ve been picking up some potato leaf hoppers. Worms are turning up in a few fields, nothing that would warrant treatment. Tomato spotted wilt virus (TSWV) symptoms are becoming apparent this week on more plants. It’s a fairly low level but clearly TSWV is out there right now.”

 

Kerry Siders, Texas A&M AgriLife IPM Agent Hockley and Cochran Counties: “The crop is excellent, the best we’ve seen in at least 4 years. Pegging is strong. There are no faults other than a few weeds. A few fields may need some help with nitrogen. We’d benefit from a little more rain, which would help canopy development and induce more pegging.”

 

Management Tip from Chemtura AgroSolutions:

   

Get Ahead—and Stay Ahead—of Spider Mites

Recent field reports indicate that spider mites are showing up in Southeast peanut fields. Your best course of action is to get ahead of these pests before they become a serious problem, so scout early and often for them. And take action when necessary with tools like Comite® II miticide to deal with infestations.

 

Entomology experts note that when treating fields with a mite treatment product, thorough spray coverage using ground application with cone nozzles and proper gallonage is necessary to attain desired results. Always read and follow label directions.

  

 

Mark Abney, Extension Entomologist, University of Georgia, Tifton: “The phone is ringing off the hook about insects. A little bit of everything is out there. Not everything is at threshold but we also don’t have thresholds for everything. In some cases people are spraying if they’re on the conservative side. Threecornered alfalfa hoppers are being treated and a variety of foliage feeding caterpillars are out there.

 

 

“Lesser cornstalk borers (LCSB) are all over the place. As dry as it’s been, that’s not surprising. Enough of them are out there now that even one or two good rain events might not be enough to make them go away. It would take a more prolonged period of wet conditions. We don’t have a lot of options at this point. Granular Lorsban would be a choice, but you need rain to move it into the soil, so if it’s a non-irrigated field and it doesn’t rain, that won’t help.

 

"If you’d sprayed early enough with Dimilin, there’s a chance it might help, but if you’ve got 60-day-old peanuts that have lapped in the middles it will be a stretch to get the material where it’s needed. LCSB are probably the scariest insect we deal with in terms of our inability to control it.

 

"A lot of irrigated peanuts are lapped or nearly to that point.”
