    This is Jack Bacheler, Extension Entomologist at NCSU with the Wednesday Cotton Insect Update for August 28.

    This week, we are certainly closer to putting cotton insects in the rear view mirror. Only stink bugs remain as a possible threat in some late cotton fields, with cotton aphids and spider mites and plant bugs no longer able to inflict economic damage.




    Even without using the stink bug card or web app for treatment decisions based on internal boll damage and week of bloom, if hardened off speckled bolls, including cracked or open bolls, outnumber small bolls in the top of plants by about 5 to 6 or 7 to one, stink bugs should no longer be an economic problem in those fields. My guess is that less than 15% of our cotton acreage is still vulnerable to stink bug damage as of today.

    Although the caterpillar toxin in early-planted WideStrike and Bollgard II cotton varieties tends to lose some of its effectiveness at this time of year, bollworm moth levels are far too low to create a problem in the coming weeks.

    It’ll be interesting to find out how much late season boll damage our producers experienced in 2013 when we conduct our annual damaged boll survey.

    That’s about it for this week. We’ll provide our last insect update tape this coming Wednesday, September 4. See you then.
