A new Focus on Cotton webcast titled “Changing Bt Technologies and Bollworm Management in Bt Cotton” helps cotton growers, consultants, and other industry experts monitor the potential impact of bollworm populations and determine when additional treatments may be advantageous. This 53-minute talk by David Kerns, Associate Professor at Louisiana State University, provides information that helps users scout for bollworms and plant injury, identify critical infestation and injury thresholds, and calculate the potential benefits of insecticide treatments.

This presentation is freely available through the Focus on Cotton webcast resource located at the Plant Management Network, containing more than 50 webcasts on various aspects of cotton crop management. The site also features Cotton Cultivated, a new resource from Cotton Incorporated that helps users quickly find the most current cotton production information available.
