CA 2235514

The present invention relates to pesticidal compositions comprising an amount of a UV sensitive pesticide and a lignin as a UV sunscreen in an effective amount to protect the pesticide against inactivation by UV radiation for extending the persistence of the UV sensitive pesticide in the natural environment to control a pest and/or for reducing the amount of the pesticide typically needed to be a commercially effective pesticide. The present invention also relates to a method for protecting a UV sensitive pesticide against inactivation by UV radiation. The present invention further relates to a method for controlling a pest comprising exposing the pest to the pesticidal compositions of the present invention.

La présente invention concerne des compositions pesticides contenant une certaine quantité de pesticide sensible aux UV ainsi qu'une lignine servant d'écran solaire anti UV, dans une quantité efficace pour protéger le pesticide contre l'inactivation provoquée par des rayons UV et prolonger ainsi la persistance du pesticide sensible aux UV dans l'environnement naturel, afin de lutter contre un parasite et/ou réduire la quantité de pesticide généralement requise pour donner un pesticide efficace commercialement. La présente invention concerne également un procédé pour protéger un pesticide sensible aux UV contre l'inactivation provoquée par des rayons UV. Elle concerne en outre un procédé de lutte contre un parasite consistant à exposer le parasite aux compositions pesticides faisant l'objet de la présente invention.
