FIELD: agriculture.
SUBSTANCE: invention relates to granules and powders of herbicide with high content of fluroxypyr-meptyl. Coated sprayed herbicide powder contains crystalline particles of fluroxypyr-meptyl coated with a mixture of surfactants, containing: a) a water-soluble nonionic surfactant which is a polyvinyl alcohol; and b) a water-soluble anionic surfactant, which is a lignosulphonic acid salt, wherein the powder contains from 350 grams (g) to 800 g of fluroxypyr-meptyl per kilogram (kg) of the powder, where the fluoxypyr-meptyl is characterized by a degree of crystallinity, making at least 80 percent, and the coated particles are not obtained by microencapsulation via inter-phase polycondensation.
EFFECT: granules demonstrate high stability during storage and high herbicidal efficiency when added to water and used by spraying for control of undesirable plant growth.
