FIELD: agriculture. ^ SUBSTANCE: invention relates to agriculture. Method of forming sprayed pesticide composition having improved properties of spray drift comprises the steps: I) providing an aqueous concentrate containing the pesticide. II) Providing an aqueous concentrate containing pesticide adjuvant or fertiliser which is a water-soluble inorganic compound. III) Formation of sprayed pesticide composition by combining water, pesticide and pesticide adjuvant or fertiliser. The aqueous concentrate of pesticide and aqueous concentrate of pesticide adjuvant or fertiliser both contain one or more polymers that are water soluble. They are formed from water-soluble monomers or monomer mixture. The monomer is water-soluble ethylenically unsaturated monomer. The polymer is a cationic, amphoteric, nonionic or anionic. The polymer has solubility in water at least 5 g in 100 ml at 25C. For application of pesticides on the land of cultivated area the pesticide composition is sprayed through irrigation equipment. ^ EFFECT: invention enables to improve control of spray drift without risk of an overdose of adjuvant/ fertiliser or pesticide. ^ 12 cl, 2 tbl, 2 ex |
