Specialists at Mississippi State University have been monitoring recent bollworm activity, which is beginning to threaten cotton containing dual gene Bt traits. They offer guidelines for determining when – or if – additional treatments may be needed.
Scott Stewart, University of Tennessee Extension entomologist, says that growers who record the date of cutout can start counting down the days until treatments for some insect pests can be ended.
Two new webcasts focusing on minimizing sticky cotton through aphid and whitefly management have been added to the Focus on Cotton online webcast resource.
According to Tennessee Extension Entomologist Scott Stewart, cotton growers are entering a critical window for managing insect pests in cotton, as immature plant bugs, stink bug and bollworm infestations may all coincide during the mid-flowering period.
With plant bug season in full force in many areas of the Southern Cotton Belt, Extension entomologists in the Mid-South have developed a list of products and treatment options for cotton growers to consider.
Now that plant bug season has arrived, Extension specialists suggest taking square retention counts along with sweep net counts prior to bloom to help with treatment decisions.
