“Farmers planted plenty of soybeans in the past 7 to 10 days, working around showers. Thank goodness we haven’t had a large, general rain. Farmers could find enough dry fields to keep going, and they’re pushing hard now to finish soybeans.
“With all the unfavorable weather, farmers weren’t able to spray herbicides earlier. A number of tank mix combinations have been going out now to take care of big winter and spring weeds, plus leave residual protection.
“Farmers weren’t able to plant all the corn they intended, and those remaining acres are going into soybeans now.”

“Everyone is through planting cotton. I think all of my guys finished before June 1 and, overall, it looks good. Most of it is coming up, thanks to these warm temperatures, sunshine and soil moisture. It’s just late.
“We are dealing with thrips in a few fields – nothing too heavy. We sprayed a few fields last week, but I think a few more will require a treatment in the near future.
“Light showers have been falling on and off, but it really hasn’t rained much yet today (afternoon, 6/8). The rain percentage for this afternoon has varied greatly from forecast to forecast, from 50% up to 80%.”

“A small amount of our cotton is starting to square.
“We’re in the middle of a pretty big thrips flight. Farmers planted quite a bit of cotton very late in May and into the first week of June, and it’s syncing with the thrips migration.
“We run into thrips issues every year, but this year they developed into an unusually high concern. Last week, I told a number of our growers that pretty much any of the cotton in the susceptible one- to two-leaf stage needs to be treated soon.
“The real challenge is deciding what to apply. We have been collecting data for several years, and it shows that acephate does not perform as well as in the past. I’ve been suggesting that people try Intrepid Edge, and I’ve been a little surprised by how many have been willing to do that. Intrepid Edge has been noticeably better in my trials. I’m not saying acephate doesn’t work, but it’s not as consistent as it once was.
“A grad student is gathering data from all over the area, collecting populations and comparing different materials. Initially, this situation with acephate seemed to only be happening in Tennessee. Some colleagues in adjoining states are now seeing some probable slippage with acephate, but it’s not everywhere. A lot of people have been using acephate for a long time because it is inexpensive, so it’s not surprising we appear to be seeing some resistance in tobacco thrips populations in some areas.
“An initial bit of information suggests that Bidrin is doing a little better than acephate. Intrepid Edge is a pre-mix that has spinetoram in it. Intrepid Edge is cheaper than Radiant, which is the same chemistry but marketed more for vegetable production. But I still wouldn’t say Intrepid Edge is cheap. You’re spending $2 per acre for thrips control with acephate compared to $8 an acre for Intrepid Edge. With low cotton prices, Intrepid Edge has been a tough sell.
“Everyone is focusing on weed control, which is normal for this time of the year. But the dicamba issue (voiding of key dicamba labels) hasn’t helped anything. On top of that, it rained today (6/9), which will force everyone out of the fields for a few days.”

“It’s raining now (6/8). We could use a small shower in a few fields, but the forecast predicts 3 to 4 inches of rain from this storm (Cristobal). Some of the late-planted soybean and cotton fields could use up to an inch, but we’re still on the east side of this storm with large rains expected. We’ll see.
“Most of our cotton is between the three- to five-leaf stage, but some late-planted cotton ranges from just out of the ground to the one-leaf stage.
“We’ve had quite a bit of thrips activity, so we’ve sprayed most fields. Thrips have been the biggest issue so far, but we also are dealing with a few weed control issues. We are fighting pigweed pretty hard, and our dicamba cutoff date was May 25, so we are trying to apply Liberty now.
“It’s almost a nightmare trying to control the weeds and avoid all the showers. For best results, you really need 8 hours of sunshine and at least 80-degree temperatures when applying Liberty. We’ve had the heat, and it’s been over 90 degrees a few days, but we can’t catch a solid day without rain.
“We have been going out with Roundup and Outlook to gain some preemergent control and kill grasses, then follow up those with Liberty to kill the pigweed.
“Most of our corn is at V9 or V10. It won’t be long before we start a pre-tassel nitrogen application. All of our corn has been laid by.
“Our soybeans are anywhere from just planted to full bloom. There’s a big difference in the ages of our soybeans, and we don’t have a lot of early planted beans this year. The majority of them are probably at V2 to V4.
“In peanuts, we’ve had more trouble establishing good, thick stands than I’ve seen in the past. I’m not sure if that’s due to seed quality or something else. All the peanuts were planted in a timely manner – not early or late – but they still struggled. I would say 90% of the peanuts did eventually come up to a good stand.”
Sebe Brown, Louisiana Extension Field Crops Entomologist
“Rainfall amounts from tropical storm Cristobal varied, depending on location and how the rain bands moved over the state. Totals ran from a tenth to about 3 tenths of an inch in some areas but increased to a half-inch to 1.5 inches on the eastern side of Louisiana. On the western side, hardly any rain fell. A cold front came through last night (6/9) and actually dropped more rain than the storm.
“We needed rain and still do. It turned dry, and we’re now heading into 10 to 12 days of hot, dry weather.
“Aphids are still out there, and we’re seeing large numbers building in a lot of cotton. Guys are either making applications or considering it. The rain at least gave us a brief reprieve from the aphids.
