PESTICIDAL MICRONUTRIENT COMPOSITIONS CONTAINING ZINC OXIDE

摘要

The invention is aqueous pesticidal-micronutrient composition which is readily dilutable in water to provide an effective amount of pesticide-zinc nutrient for spray application to crops which, prior to dilution, comprises by weight of the total composition: (a) about 10 to 60 % of chlorothalonil 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 heteropolysaccharide gum; (d) about 1.0 to 10 % zinc oxide having an average particle size of 1 to 10 microns; and the balance being water.
