Patent ID: 8563469

Claim:
An insecticidal composition comprising by weight based on the total weight of the composition: (a) from about 9 to about 91% of one or more anthranilic diamide insecticides; and (b) from about 9 to about 91% of an acrylate/methacrylate-based random copolymer component having a water solubility of at least 5% by weight at 20° C., a hydrophilic-lipophilic balance value of at least or about 5 and an average molecular weight ranging from about 1,500 to about 50,000 Daltons; wherein component (a) comprises at least one compound selected from anthranilic diamides of Formula 1, N-oxides, and salts thereof, wherein X is N; R1 is CH 3 , Cl, Br or F; R2 is H, F, Cl, Br or —CN; R3 is F, Cl, Br, C 1 -C 4 haloalkyl or C 1 -C 4 haloalkoxy; R4a is H, C 1 -C 4 alkyl, cyclopropylmethyl or 1-cyclopropylethyl; R4b is H or CH 3 ; R5 is H, F, Cl or Br; and R6 is H, F, Cl or Br; and wherein component (b) is selected from acrylate/methacrylate-based random copolymers of Formula 2, where each R 7 is independently selected from H and CH 3 ; q and y are relative percentages of each acrylate/methacrylate monomer in the random copolymer such that 0.02≦q≦0.98 and 0.02≦y≦0.98, and the sum of q and y is 1.0; 20≦z≦20,000 Q is benzyl, glycidyl, C 1 -C 20 straight chain alkyl, C 3 -C 20 branched alkyl, or 2-phenoxyethyl, and Y is hydroxyethyl or 3-hydroxy propyl, or Y is a functional group derived from the reaction of a glycidyl group with diethylene glycol, triethylene glycol, tetraethylene glycol, or 1,6-hexanediol, or Y is —(CH 2 CH 2 O) 2 —H, or —(CH 2 CH 2 O) 9 —H, or and Y is —(CH 2 CH 2 O) 30 - when Q is benzyl or phenoxyethyl, and wherein the ratio of component (b) to component (a) is about 1:10 to about 10:1 by weight.
