Title
(EN) DRIFT REDUCTION ADJUVANT COMPOSITIONS AND METHODS OF USING SAME
(FR) COMPOSITIONS D'ADJUVANT DE RÉDUCTION DE DÉRIVE ET LEURS PROCÉDÉS D'UTILISATION
Abstract
(EN)
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.
(FR)
L'invention concerne une composition d'adjuvant de réduction de dérive et des aérosols agricoles contenant de telles compositions agricoles qui contiennent de l'eau, un modificateur de rhéologie, par exemple de la gomme de guar ou de la polyacrylamide, un émulsifiant tel qu'un émulsifiant de polyoxyéthylène sorbitanne, et une huile. Lorsque l'aérosol agricole contenant la composition d'adjuvant de réduction de dérive et un pesticide est éjecté par une buse agricole, il produit moins de gouttelettes de diamètre inférieur à 150 µm et réduit, conserve ou augmente (par exemple, jusqu'à 30 %) le nombre de gouttelettes ultra-grossières de diamètre supérieur à 622 µm par rapport à un aérosol agricole du pesticide sans la composition d'adjuvant de réduction de dérive pulvérisé dans les mêmes conditions.
