Unique Production Season Ahead

When I first moved down to Port Lavaca, at a crop tour, growers were talking how much experience they had farming.  One replied he had “1 year experience, 40 times.” I think there is a lot of truth to that statement.  It seems each year presents it’s own production challenges. So how is 2020 different from other years? There are two obvious differences: lower than normal rainfall and higher than average temperatures. Much of insect and plant activity occurs as a response to three variables. These variables are… Read More →

Headworms, Stink Bugs and Sugarcane Aphids in Grain Sorghum

We have been finding Rice Stink Bugs, Headworms and Sugarcane Aphids in Sorghum fields  of the Mid-Coast of Texas. 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 sorghum heads per acre. Look here for an economic thresholds calculator. I am using an economic threshold of 0.5 – 1 stink bug per head,… Read More →

Stink Bugs and Headworms in Grain Sorghum

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

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 →
