South Texas audio updates

We have been recording pest updates in effort to provide a brief audio version of South Texas newsletters and blog posts. The reports include crop production and pest management updated from South Texas, including the Rio Grande Valley, Coastal Bend and Mid-Coast. You can get these by following this link: https://www.texasinsects.org/south-texas.html The latest edition is: 4/16/2021 (audio file) Fall armyworm and corn earworm feeding present in corn and sorghum whorls, but threshold is generally 30% defoliation across most plants. Corn leaf aphids and sugarcane aphids generally being controlled by… Read More →

Stink Bugs in Soybean Fields

Over the past week we have been finding increased numbers of stink bugs in soybean fields.  Most of these stink bugs were green, southern green and red-banded stink bugs. My preferred method to scout for stink bugs is the sweep net, but a good alternative is the drop cloth. As a last resort, you can shake the plants over the furrow and see what falls onto the ground. The disadvantage of shaking on the ground is you may miss some of the insects that can fall into cracks… Read More →

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 →

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 →

Stink Bugs in Cotton and Soybeans

While many fields are harvest ready, stink bugs are potential pests in the cotton and soybean fields that have yet to reach maturity. Cotton should be scouted for stink bugs until 350 heat units, or approximately 15 days, after the field has cutout (<5 NAWF).  Scout by opening 20-25 one-inch bolls and inspecting the bolls for evidence of internal feeding. Treat a field with more than 20% evidence of internal feeding. Soybeans are susceptible to stink bug damage until the beans reach maturity. Some entomologists would say soybeans… Read More →
