OVERVIEW

Insects persist. Loopers remain a player in parts of the Southeast and the Delta. Corn earworms also persist on a wide basis, with 3 and even 4 apps reported on some fields. Stink bugs are in the mix on a wider basis, too. Late last week Kentucky reported excessively high counts of fall armyworm and corn earworm moths. Entomologists are variously describing 2010 as a "buggy" or "wormy" year. Hardly scientific terms but descriptive, nonetheless.

Soybean harvest. More beans are being cut in the Midsouth. Hefty yields are hard to find, even in some irrigated production. Dryland beans took it on the chin, not just from low rainfall amounts but from the prolonged heat.

Soybean rust. No new reports about soybean rust since last week’s isolated find in North Carolina. But with Hurricane Earl hugging the Atlantic Southeast shore, some preventive fungicide treatments have likely been made.

CROP REPORTS

Herbert Jones Jr., Ind. Consultant, Leland, Miss.: "We sprayed late soybeans 2 to 3 weeks ago, which took out beneficials, and now soybean loopers and stink bugs are coming back. Insects are concentrating in later fields. We’re about a third of the way through cutting beans, plus most of our remaining MG IVs have turned. Soybean yields range from 8 to 10 bu/acre in burned up situations to 50-plus in irrigated fields, with maybe some 70 to 80 bu/acre averages in places."

Ames Herbert, Virginia Extension Entomologist: "We were putting in a looper trial in North Carolina today (8/31), about 20 to 25 miles south of the state line, and moths were flying around like crazy. We counted 150 loopers in 15 sweeps, so that definitely was a hot spot. We put out every material and combination that seemed appropriate, based on what we have been doing and also what people in other areas have been using against heavy populations. They’re starting to move into a few fields in Virginia, although we haven’t had calls about high numbers. Reports I’m getting are from consultants who are checking closely. We’re still getting calls about resprays for corn earworms in soybeans. They’re just not letting up. A lot is happening in states around us. Whitefly killed a 3-acre spot in a soybean field in Delaware, and we’re seeing whitefly develop in some fields here. This is similar to what we’d find in cotton before Bt when we’d make 2 sequential sprays for bollworms, then see whitefly build after beneficials were eliminated. With all the spraying in soybeans this season, we’ve certainly left the door open for whitefly, and we don’t have much experience with them in soybeans. Brown marmorated stink bugs aren’t thick in Virginia, but they’re inundating fields in Maryland. In terms of pests, this is one of the wildest summers we’ve ever experienced. And now that soybean rust has been found in North Carolina and we’ve got a hurricane that might spread spores, growers are concerned about whether to put out a fungicide and try to get something out for insects while they can still get in the field. I’m getting calls about those situations. In some cases, looper counts are high enough to justify spraying. In other cases, treatments probably aren’t needed. But some growers will go ahead and treat to lower risk. Some full-season MG IV soybeans are yellowing and are mostly safe now, but our doublecrop beans are still very vulnerable and will be for another month."

Curt Johnson, CRC Ag Consulting, LLC, Lake Village, Ark.: "All of my dryland beans have been cut, and we’re moving into some early irrigated fields now. We treated two-thirds of the beans I’m scouting for insects. In some varieties, stink bug pressure wasn’t significant all season. We went through several cycles of adults, but numbers never rose enough to treat. But now we’ve got a hatch, and immatures are probably at 50% of a treatment level, with beans at R6, so we may end up treating. Where I’ve sprayed stink bugs, it was incidental to treating loopers, so we added acephate."

Phillip Roberts, Extension Entomologist, Tifton, Ga.: "We’re primarily dealing with stink bugs in soybeans, then secondarily with soybean loopers. The loopers aren’t a real common thing. But they’re scattered around in enough areas that you need to scout. I’ve gotten a couple of reports about corn earworms on soybeans, mainly in east Georgia."

Joey Branch, ProAg Services, LLC, Newport, Ark.: "Soybean loopers have really blown up in the beans over the last 10 days, and we’re still fighting bollworms. I know we’ve got 3 treatments out on a big part of our crop, with possibly even 4 in places, and we’ve still got a long way to go on some fields. Some early MG IV dryland beans are being cut, and we might be into some irrigated beans now, too. No yields yet."

Carl Hobbs, Agronomist, Helena Chemical Co., Ashburn, Ga.: "Some soybeans are being treated for loopers. Corn harvest is moving a little slower. On average, corn yields are back up from the disappointments in 2009."

Billy McLawhorn, McLawhorn Crop Services, Inc., Cove City, N.C.: "Insect applications on soybeans have been continuous for several weeks. We’re still dealing with a little corn earworm pressure in some later beans and also have loopers and bean leaf beetles. Loopers are widespread. They’re not in super-high numbers in many places, but we definitely have heavy pressure in some areas. We’ve got some soybeans that, in fact, haven’t been treated at all, but then a lot of fields have been treated twice and some have received a third application. That’s kind of unusual here, although last year was a little like that, too. Wwo-thirds of our corn has been picked. Yields range from 20 bu/acre to 150 in some fields that received occasional rain. Everything this year looks better than the corn."

Allen McKnight, Delta Ag Consulting, Greenville, Miss.: "We’re spraying stink bugs in later soybeans. We’re just about through watering late MG Vs. Some might be watered another time, but irrigating into September is kind of iffy. Those are the greenest beans we still have. The rest are at R6.5 to R7 or have been cut. On the south end of the area I work, we might be 50% finished with soybean harvest."

Jeremy Greene, Clemson University Cotton Entomologist, Blackville, S.C.: "Soybeans have quieted down a little, but we’re still dealing with loopers in places and probably will be getting more into stink bugs in the next couple of weeks. As of last week, we now have found the invasive kudzu bug in 15 counties."

Victor Roth, Roth Farm Service, Malden, Mo.: "I mostly wound up soybeans last week. They were either mature or we treated them one more time for a combination of loopers and stink bugs. I’ll check a few fields one more time, and that will be it. Some MG 3.8 were getting close to the point last week that the grower could have applied a defoliant."

Zach Ingrum, Field Rep, Southern States, Athens, Alabama: "Last week we finished up some fungicide applications in soybeans and did some general overspraying with it for insects. Some beans have been cut in the last 3 weeks. Yields haven’t been particularly good. Some early MG IVs last week were in the 10 to 20 bu/acre range. The beans actually had enough rain that you would have expected closer to 30, but all those days with high temperatures took a toll. A lot of wheat was booked when the market jumped up, but interest died down as other commodity prices increased."

Terry Erwin, Morehouse Parish Extension Agent, Bastrop, La.: " Some MG V soybeans are still being sprayed for insects, but we’re not dealing with the heavy looper pressure that developed elsewhere. We sprayed Intrepid, and nothing seems to be coming back. We’ve cut 80% of the corn and are into soybeans. I’m hearing irrigated corn yields of 140 to 200 bu/acre. Not everybody hit a home run, but at least most of it is out of the field now."

Ron Smith, Alabama Extension Entomologist: "Soybean loopers are out there, and we need to be looking for them. We’re still not finding some of the heavy pressure that they’re dealing with in other parts of the South, but they are around. At the Gulf Coast REC early this week they were right at threshold. The last thing you want is to see defoliation in the top of the canopy because that’s what they do in the last 48 to 72 hours. Before that, they will have been down in the canopy where you can’t see damage without getting into the field. When they’re small, you almost can’t recognize them as a caterpillar. They’re almost like little hairs that fall on the drop cloth. If you see a lot of little green worms – dozens and dozens of them and they’re so small you can’t ID them – they probably are loopers. The exception might be velvet bean caterpillars, but that would be closer ot the coast. Loopers are unusual in that certain insecticides either work on them or they don’t. Pyrethroids are out. On a side note, fall armyworms are again hitting hay fields in the Wiregrass after having a population just 2 weeks ago. In other words, we’re not even having to wait for a generation. If you treated them earlier in August, don’t assume they’re gone for good."

Lance Honeycutt, Jimmy Sanders, Inc., Jonesboro, Ark.: "Soybean loopers are kind of hit or miss. I’m spraying mostly east of Crowley’s Ridge and around Harrisburg. But we’re not having to spray west of the ridge yet. Numbers are high but still not at some of those extreme levels I’m hearing about in other places. We’ve also treated stink bugs in some cases. We terminated watering on our earlier MG IV fields. They’re starting to turn and drop leaves."

Dominic Reisig, NCSU Extension Specialist, Entomology, Plymouth, N.C.: "Since last week, more growers have had to treat a second time for corn earworms, and a few may be going into a third application. I’m hearing reports about some product shortages. Looper numbers are going up in places but are generally widespread, even in more western parts of the state where they normally aren’t found. The higher numbers right now seem to be north of the Albemarle Sound. In some cases, 200-plus loopers were turning up in 15 sweeps. Stink bugs also are being treated in areas with the heavier looper pressure. Depending on the location, it’s either greens and browns or just browns. I was in fields today (9/1) in Pamlico County with stink bug numbers that ranged from low to moderate, then saw high levels in Beaufort County."
