Abstract

La présente invention a pour objet un concentré émulsionnable comprenant un pesticide insoluble dans l'eau, de l'alcool benzylique, un lactate d'alkyle et pas plus de 40 % en poids de diméthylsulfoxyde. La présente invention a pour autre objet une émulsion pouvant être obtenue par mélange d'eau avec le concentré émulsionnable; un procédé pour la préparation du concentré émulsionnable; et un procédé pour la lutte contre des champignons phytopathogènes et/ou de la végétation parasite et/ou une attaque indésirable par des insectes ou des acariens et/ou pour la régulation de la croissance de plantes, consistant à laisser le concentré ou l'émulsion agir sur les animaux nuisibles respectifs, leur environnement ou sur les plantes cultivées devant être protégées des animaux nuisibles respectifs, sur le sol et/ou sur les plantes parasites et/ou sur les plantes cultivées et/ou leur environnement.
