Abstract
Drift reduction adjuvant composition and agricultural sprays containing such agricultural compositions contain water, a rheology modifier (e.g., guar gum or polyacrylamide), an emulsifier such as a polyoxyethylene sorbitan emulsifier, and an oil. When the agricultural spray containing the drift reduction adjuvant composition and a pesticide is delivered from an agricultural nozzle, it produces fewer droplets less than 150 μm in diameter and either reduces, maintains or increases (e.g., by up to 30 percentage points) the number of ultra-coarse droplets above 622 μm in diameter compared to an agricultural spray of the pesticide without the drift reduction adjuvant composition sprayed under the same conditions.
