Abstract

Lack of consistent regulation and marketing of adjuvants and complexity of the interaction among plant, herbicide, environment, water quality, and adjuvant have caused general confusion in adjuvant selection among growers. Choosing the best adjuvant is difficult. Growers must chose from thousands of commercial products and are confused by product descriptions with unfamiliar ingredients and functions. Confusing recommendations, aggressive marketing, and lack of unbiased research and educational information make matters even worse. Manufacturer lists of approved adjuvant products, guidelines that set minimum requirements to qualify adjuvants for use with herbicides, and packaging effective adjuvants with herbicides either in the herbicide formulation or packaged in a different container help reduce grower confusion. University adjuvant research and education have aided grower knowledge and understanding of adjuvants by field testing adjuvants and have influenced herbicide label wording and recommendations.
