Not much is happening in cotton right now in terms of insect pests. The hot, dry weather seems to have things on hold, for the most part. Spider mites are common on a lot of field edges but are not widespread. We are not seeing much evidence of square loss to plant bugs (in untreated fields) and square retention is in the 90% + range. A few stink bugs, mostly brown stink bugs, are beginning to show up and soon we will begin assessing bolls for stink bug damage using our newly released ‘Decision aid for stink bug thresholds in Southeast cotton’ which presents a dynamic internal stink bug damage percentage threshold (changes as the crop matures) that begins with 50% internal damage in the first week of bloom. We will post more details soon.
