Cotton Insect Report

Posted on by

Cotton plant maturity ranges from 9-14 true leaves. We began seeing blooms in a few fields. The fields with blooms had 6-7 nodes above white flower, which shows the effect of drought stress. The water demand of a crop increases significantly as bloom nears and fruit production begins. If we do not get rainfall soon, expect to see wilting cotton fields in the afternoons. Fortunately, we have not seen insect pressure requiring insecticide applications. Cotton fleahoppers have been difficult to find in most fields. Few fields have more… Read More →

Squaring Cotton and Drought

Posted on by

Most cotton fields are squaring so the cotton fleahopper is the primary pest of interest in these fields. I use an economic threshold of 15 cotton fleahoppers per 100 plants. Adults and nymphs count the same. The cotton fleahopper will feed on the soft plant parts in the terminal of the plant. They cause injury when they feed on small squares causing the square to be “blasted” and then abscise, or fall off the plant. Once a square is larger than a pin head, it is considered safe… Read More →

Cotton Near Cutout

Posted on by

Much of our cotton fields are at or near cutout.  The fields we have been in this week range from 2-6 nodes above white flower (NAWF).  Keep in mind the time for a white bloom to  mature into an open boll is around 50 days. We are finding bollworms in non-Bt and 2-gene Bt cotton such as Bollgard 2 and Twin-Link cotton varieties.  I have not found much damage or worms in the 3-gene cotton varieties containing the VIP gene. Treat cotton fields when square and boll damage… Read More →
