One Texas Department of Agriculture continuing education unit is available in drift minimization.

Mark Matocha, Ph.D., AgriLife Extension pesticide specialist, will be the featured speaker.

“An expert on drift, Dr. Matocha will cover different types of drift, factors that influence drift and drift strategies,” said Morgan Treadwell, Ph.D., AgriLife Extension range specialist, San Angelo. Treadwell is a series co-creator, along with Brittany Chesser, AgriLife Extension aquatic vegetation program specialistBryan-College Station.

Program topics

“Anyone who applies herbicides needs to have a basic understanding of spray drift in order to prevent unintended plant damage,” Matocha said.

The drift minimization program will cover:

  • Particle drift.
  • Vapor drift.
  • Physical characteristics of spray solutions.
  • Factors that influence drift.
  • Applicator influence on drift.

Strategies and methods to minimize drift will also be covered and will include discussions on delayed applications, nozzle type and droplet size, boom height and adjuvants.
