Disclosed is 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 a nonionic ethylene oxide-propylene oxide block copolymer component having a water solubility of at least about 5% by weight at 20 °C, a hydrophilic-lipophilic balance value of at least about 5 and an average molecular weight ranging from about 1500 to about 20000 daltons； wherein the ratio of component (b) to component (a) is about 1 : 10 to about 10 : 1 by weight. Also disclosed is a geotropic propagule coated with an insecticidally effective amount of the aforedescribed composition. Further disclosed is a liquid composition consisting of about 5 to 80 weight % of the aforedescribed composition and about 20 to 95 weight % of a volatile aqueous liquid carrier, and a method for protecting a geotropic propagule and plant derived therefrom from a phytophagous insect pest, the method comprising coating the propagule with an insecticidally effective amount of the aforedescribed liquid composition and then evaporating the volatile aqueous liquid carrier.Se describe una composición insecticida que comprende lo siguiente en peso con base en peso total de la composición: (a) de aproximadamente 9 a aproximadamente 91 % de uno o más insecticidas de diamida antranílica； y (b) de aproximadamente 9 a aproximadamente 91 % de un componente de copolímero de bloque de óxido de etileno-óxido de propileno no jónico que tiene una solubilidad en agua de al menos aproximadamente 5 % en peso a 20 0C, un valor de balance hidrofílico-lipofílico de al menos aproximadamente 5 y un peso molecular promedio dentro del intervalo de aproximadamente 1500 daltons a aproximadamente 20 000 daltons； en donde la relación entre el componente (b) y el componente (a) es de aproximadamente 1 : 10 a aproximadamente 10 : 1 en peso.
