IPM in Fall Corn Production

Cotton in Bloom and IPM

Posted on by

Many of the cotton fields in South Texas are in bloom. Once cotton is blooming, we need to change our scouting methods. Plant water use is increasing rapidly and the insects that cause yield loss are changing. Now is the time to start counting Nodes Above White Flower (NAWF). This will help you know how the crop is progressing and when insects stop being an economic pest. Count NAWF by finding the first position white flower and counting the number of nodes (branches) above the branch with the… Read More →
