Aerial Spray Adjuvants for Herbicidal Drift Control

摘要

Increased public concern about pesticides requires that foresters reduce drift and insure precise application of herbicides to the area requiring treatment. Drift control is necessary near waterways and other ecologically sensitive areas. This publication discusses available drift control adjuvants for herbicidal sprays. These include invert emulsions, thickening agents, particulating agents, and foam sprays. Commercially available adjuvants are described and their use, advantages are discussed. Thickening agents and foam sprays show special promise for drift reduction in aerial application of herbicides on forest lands.
