Drought is creating complications for cotton insect pest control for Louisiana producers. So far, for corn and soybean insects, “it’s quiet.”
Sebe Brown, LSU Extension entomologist, says uneven cotton stands creates unusual insect problems. Some fields have cotton at the two true-leaf stage with some 11 or 12 true-leaf cotton that has squares. Some producers are controlling thrips on one side and plant bugs on other rows at the same time.”
Brown says Bidrin may be the best option. It controls plant bugs and thrips. “We don’t have a lot of options. We can use acephate, but are concerned about spider mites because it’s so dry and so hot. Acephate also could flare aphids and other insects. Growers want to stay soft early in the season. That’s what we practice with IPM; try not to flare any secondary pests as much as possible.”
He says the unusual season, with uneven cotton, may mean producers have to break out some of the tools they typically use later, because that’s about all they have to control “a myriad of pests on early season and almost pre-flower cotton.”
So far, he's seen little bollworm pressure and no red banded stink bugs.
He says the crops need rain.
