Nodes Above White Flower

Counting Nodes Above White Flower (NAWF) is a good way to monitor a cotton field’s maturity after bloom. The process is done by finding the first position white flower and counting the number of nodes (branches) above the branch with the white flower. The last node to count is the highest node with an unfurled main stem leaf (at least 1-inch wide). NAWF is useful for management of your cotton crop. By tracking NAWF, you can see how the crop is maturing compared to an expected growth curve. … 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 →

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 →
