“How to Minimize Chemical Trespass, aka Spray Drift” will be the topic of a Nov. 1 webinar, part of the Texas A&M AgriLife Extension Service’s ecosystem science and management unit series.

“Chemical drift should be avoided because it can result in damage to non-target plants, reduced control of target plants, and may cause crop injury or property damage to your neighbors,” said presenter Dr. Alyson McDonald, AgriLife Extension range specialist in Fort Stockton.

McDonald will discuss particle and vapor drift along with factors that contribute to chemical drift and steps that should be taken to minimize any problems. She will conclude with a brief discussion about mixing herbicides and sprayer calibration.

The webinar is scheduled from noon to 1 p.m., according to Brittany Grube, graduate assistant and webinar coordinator. Only participants seeking Texas Department of Agriculture continuing education units must pay a $10 fee on the website.

Texas Department of Agriculture licensed agricultural pesticide applicators participating in this webinar can earn one continuing education unit in drift minimization.
