Stink Bugs and Headworms in Grain Sorghum

Posted on by

Some sorghum fields across the Mid-Coast of Texas have been inundated with Rice Stink Bugs or Headworms; or in some cases, both stink bugs and headworms. Adding to this problem, I have received several reports of pyrethroid insecticides failing to control rice stink bugs. Scout sorghum using a 2-gallon bucket and beat heads into the bucket and see what is being captured in the bucket. Look here for a brief video. Economic thresholds for stink bugs and headworms depend on the cost of control, expected crop value, and… Read More →

Cotton Fleahopper Numbers on the Rise

Posted on by

Cotton fields range from pinhead square to early bloom. Most fields are susceptible to cotton fleahopper damage and the potential for bollworm losses. We are finding cotton fleahoppers in numbers as high as 1 per plant, averaging around 20-30 per 100 plants. Continue to scout for cotton fleahoppers through the first week of bloom. This pest may cause fruit shed of small pinhead squares. Squares larger than matchhead size are generally safe from fleahopper damage. Once the plant has reached bloom, 80-90% of the fruit that will be… Read More →

Cotton IPM Update – 5/26/2017

Posted on by

Cotton maturity across the Mid-Coast ranges from half-grown square to near cutout. Pest insects to be aware of include cotton fleahopper, bollworms, stink bugs and verde plant bugs. Continue to monitor young cotton for cotton fleahoppers until the first week of bloom.  If you have a decent fruit set at bloom of at least 70% retention, the cotton fleahopper should not be a pest after first bloom. By bloom, the cotton plant should have 80% or more of the harvestable fruit.  Since the fleahopper is not able to cause square loss to squares larger than… Read More →
