Adjuvant Study
Adjuvants for post-emergence herbicides
Spray adjuvants are used with postemergence herbicides to help overcome the barriers that impede movement of the herbicide from the leaf surface to the interior of the cell.

There are three primary types of adjuvants used to enhance herbicide performance: surfactants, crop oil concentrates(COC) and ammonium fertilizers. (Utility adjuvants are not covered)

Sometimes labels give users options on what adjuvant to use with respect to environmental conditions, target species, and tank-mix partners. For example, hot, dry weather hardens plants off and reduces herbicide absorption. Under these conditions the higher rates of a COC or surfactant would be beneficial. Under cool, wet conditions the cuticle often is thinner and less of a barrier to absorption. A surfactant might be more appropriate than a COC under these conditions in order to reduce the risk of crop injury. Ammonium based fertilizers are especially important for many herbicides when velvetleaf is present. Also be sure to consider the impact of the spray additive on tank-mix partners. The use of spray additives for one product may not be appropriate for another product.
