Managing Spray Drift and Herbicide Application
Techniques Success Kit | Verified Quizzes + Top-
Scoring Assignments | A+ Guaranteed
Droplet Size - Larger nozzles increase droplet size at same output.
Drift Potential - Minimize by selecting less volatile pesticides.
Drift Managing Adjuvants - Added to reduce spray drift risk.
Buffer Zone - Distance protecting sensitive areas from pesticide application.
Sensitive Areas - Habitats vulnerable to pesticide drift, e.g., water bodies.
Buffer Zone Distances - Specified by pesticide labels for sensitive areas.
Weather Conditions - Affect buffer zone sizes, especially wind speed.
