  • Ultra violet radiation lignin protected pesticidal compositions
    Patent number: 5994266
    Abstract: 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.
    Type: Grant
