A lot of cotton acres are just about to the point of letting go for the season, but late season pests are presenting growers with difficult management decisions. Pests vary across the Midsouth, but many areas are still fighting spotty plant bugs and a second wave of bollworms.
Plant bugs are still around, but many see the large stink bug populations coming to an end in a couple weeks. Stink bugs are at typical levels, but don’t let them sneak in with lapses in sprays for plant bugs.
Cotton gathered substantial heat units last week, but the crop is still a couple weeks late, on average, across the Midsouth. Fingers are crossed for a warm fall with little to no rain to finish out the cotton crop. A little early planted cotton in Mississippi is at cutout, so the countdown begins.
Stink bug and bollworm populations are increasing, but this is just the beginning for some areas. Although spotty in Louisiana and Arkansas, some growers in these areas are still fighting an uphill battle with plant bugs.
More rainfall across the board makes for an abnormal July following suit for the first half of 2021. No one is complaining, but concerns are growing about the ability to make timely Pix applications.
Rain continues over much of the Midsouth providing a break from many pests for some but creating difficulties with Pix applications. Many areas saw rain for four days straight over the weekend, and there’s more in the forecast for this weekend. Just as the cotton was starting to pick back up, more water.
Midsouth Cotton: Pest Populations Rising — And It Hurts Worse After a Rough Start to Planting Jul 2, 2021
Plant bugs continue to increase, and bollworm populations are expected to rise soon as more corn hits brown silk. Plant bugs have been at treatment level in many areas for about two weeks and continue to require treatments. Stink bug populations are also rising, and redbanded stink bugs have been spotted in very low numbers.
After mid-June floods, growers were forced to access fields and make the tough decision to replant this late in the season or not. Other areas are looking to irrigate as temperatures continue to rise.
