Use of N-substituted pyrrolidone to promote the penetration of pesticide active ingredients

Abstract

Substances are provided which are suitable for promoting the penetration of pesticidal active ingredients into plants or into non-plant pests in an advantageous manner. [Solution] A plant protection agent containing a) 1 to 90% by weight of one or more N-substituted pyrrolidones of formula (I), and b) 1 to 90% by weight of one or more pesticide active ingredients, wherein component b) is selected from the group consisting of fungicides, bactericides, insecticides, miticides, nematicides, plant growth regulators, plant nutrients, repellents, molluscicides and / or rodenticides, and component b) is selected from systemic pesticide active ingredients. TIFF2022088619000028.tif20170 [R represents a linear or branched saturated alkyl group having 3 to 6 carbon atoms, in which H in the alkyl group may be substituted with methoxy, and 1 to 6 H in the pyrrolidone ring may be substituted with methyl]
