Disclosed is an insecticidal composition comprising by weight based on the total weight of the composition: (a) from about 9 wt % (weight percent) to about 82 wt % of one or more anthranilic diamide insecticides; (b) from about 9 wt % to about 82 wt % of a triblock copolymer component having a water solubility of at least about 5% by weight at 20° C.; wherein the ratio of component (b) to component (a) is about 1:10 to about 10:1 by weight; and (c) from about 9 wt % to about 82 wt % of a polymer crosslinking agent having water solubility of least about 5% by weight at 20° C.; wherein the ratio of component (b) to component (c) is about 1:10 to about 10:1 by weight, and wherein the weight percents are based on the total weights of (a)+(b)+(c). Also disclosed is a geotropic propagule coated with the insecticidal composition. Further disclosed, is a liquid composition comprising, the insecticidal composition, and a method for protecting a geotropic propagule and plant derived therefrom from a phytophagous insect pest.
