Pest Update and 2020 Insect Thresholds
This week we have been finding low numbers on insect pests in cotton, grain sorghum and soybeans. Cotton ranges from 1/3 grown square to mid-bloom. While most fields are below threshold, we have found a few fields with 30-40 cotton fleahoppers per 100 plants. Continue to monitor for cotton fleahoppers until bloom and treat when they exceed an economic threshold of 15 per 100 plants. Blooming cotton has had significant bollworm moth flights this week but so far, egg numbers have been low. Bollworms are important pests and should… Read More →
Thrips and Fleahoppers in Some Cotton Fields
This week while scouting cotton fields in Calhoun, Refugio, and Victoria Counties, we have found thrips, cotton fleahopper, and aphids. A few young cotton fields have thrips above economic levels of 1-2 per true leaf. This is not a comment I am fond of making because, I rarely think of thrips as an economic pest in cotton fields of the Mid-Coast. The problem we are seeing is more of a factor of lack of rainfall than the presence of thrips. In most years, our cotton fields are growing… Read More →
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 →

Early Season Cotton IPM
The oldest cotton in the Mid-Coast is squaring and the youngest is just emerging from the ground. Pest management in early season is primarily focused on two or three insect pests: Thrips, Cotton Fleahopper and Aphids. It is important to consider the pest, its numbers and the crop stage when deciding whether or not to add an insecticide to the tank. Even if it only costs $1, an unneeded tank partner will reduce crop profits. Thrips can be a yield limiting pest until the cotton plants have 4-5… Read More →
