Pest Update and 2020 Insect Thresholds

Posted on by

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 →

Stink Bugs in Sorghum, Cotton and Soybeans

We have reached the time of the growing season when Stink Bugs are the primary pest in most of the row crops on the Texas coast. Sorghum maturity is from bloom to soft dough and will be susceptible to stink bugs until hard dough. Scout for stink bugs and headworms using a bucket to beat sorghum heads into until you have sampled 10.  Then stop and count the stink bugs and headworms in the bucket.  This should be done at 10-20 places per field and average the number of stink bugs… Read More →

Mid-Coast Grain Sorghum Update

Posted on by

Grain sorghum maturity ranges from boot to soft dough.  Some fields are turning color. We are finding varying populations of Sorghum Midge in fields ranging from 0-5 per head.  Treatment thresholds are 0.5-1 midge per head depending on the number of flowering heads per acre. We are finding headworms in Refugio County sorghum fields ranging from 0-4 per head.  Many of these are fall armyworms.  The economic threshold for headworms ranges from 0.15 to 1 large worm (> 0.5 inch) per head.  For medium worms (0.25-0.5 inch) the ET… Read More →
