Abstract

L'invention concerne une composition insecticide et acaricide. Cette composition comprend deux composants actifs, A et B. Le composant actif A est l'acrinathrine et le composant actif B est le fenpyroximate et le rapport pondéral entre les deux composants varie de 1 : 30 à 30 : 1. L'invention concerne également un procédé de préparation de la composition et son utilisation. Les résultats expérimentaux montrent que la composition insecticide décrite dans la présente invention se caractérise par une synergie importante, exige des doses réduites et permet une baisse du coût de la prévention. Cette composition insecticide et acaricide permet de lutter efficacement contre de multiples types d'organismes nuisibles affectant les arbres fruitiers, les légumes et les cultures de rapport. En combinant des insecticides présentant différents mécanismes et modes d'action, on parvient à réduire efficacement les doses des divers agents, ce qui permet d'élargir le spectre de la lutte insecticide, de retarder la résistance des organismes nuisibles aux substances actives et d'améliorer la prévention.
