Cotton IPM Update 5-30-25

Cotton Maturity ranges from squaring to bloom.  We are still finding fleahoppers in some fields. In fact our insecticide test had mostly of adult cotton fleahoppers and some Verde Plant bugs this morning before the rain.  The treated plots had very few nymphs but the untreated cotton had adults and nymphs at a 1:1 ratio.

We are seeing control with all of the products at 7 days after treatment, but the nymph counts for Bidrin was was not different from the untreated nymph counts.

Once you find 1 inch bolls it’s time to be looking for stink bug damage. The warts on the inside boll wall will be caused by stink bugs, but Verde plant bugs can also cause warts and be just as damaging. Use the table below for treatment decisions.
