Weed Resistance and Pest Management in Cotton [2026]

OVERVIEW

The purpose of this course is to give the reader an overview of key practices that can help avoid or delay selecting for herbicide-resistant weeds and pesticide-resistant pests while managing weeds and pests in the field, particularly for cotton growers.

Weeds are defined as any plants that “interfere with the growing of crops or ornamental plants; endanger livestock; affect the health of people; interfere with the safety or use of roads, utilities, and waterways; or are visual or physical nuisances." Weeds can pose fire hazards and exacerbate allergies. They can clog canals, harbor insect pests, and poison people and animals.
