An aqueous pesticidal-micronutrient composition is described which is readily dilutable in water to provide an effective amount of pesticide-zinc nutrient for spray application to crops. Prior to dilution, the composition comprises, by weight of the total composition: (a) about 10 to 60% of an essentially water insoluble pesticide component having an average particle size of approximately 1 to 10 microns; (b) about 1.0 to 10% of at least one nonionic surfactant; (c) about 0.02 to 1.0% of a hetropolysaccharide gum; (d) about 1.0 to 10% zinc oxide having an average particle size of 1 to 10 microns; and optionally additionally: (e) up to about 8.0% anionic surfactant; (f) up to about 5.0% antifoam agent; (g) up to about 10.0% anticaking agent; (h) up to about 2.0% protective colloid; (i) up to about 10.0% freeze point depressant; (j) up to about 1.0% preservative; and (k) up to about 5.0% chelating agent; to a total of 100% or less. The balance, if any, is water. Also described are pesticidal-zinc micronutrient compositions in the form of wettable powders, and pesticidal-zinc wettable powder compositions in the form of spray dried disposable granules. |
