The relationship of spray adjuvant surfactant properties to pesticide spray application volumes

摘要

Over 100 pesticide labels recommend the use of a spray adjuvant to enhance efficacy of the active ingredient. Many of these labels require the use of an adjuvant. Imazethapyr requires not only the use of a nitrogen-based fertilizer, but for some applications, the use of a crop oil concentrate. The crop oil concentrate requirement specifies a given volume of adjuvant per hectare. The wetting properties, and/or surface chemistry, play a vital role in the usefulness of the crop oil concentrate.
