COMPOSITION CONTAINING SYSTEM OF ADJUVANTS AND FILM FORMING AGENTS FOR FUNGICIDE SPRAYING BOARDS AND METHOD FOR TREATING A PLANT

摘要

the adjuvant composition of this invention comprises one or more derivatives of surfactants, where at least one of the surfactants is classified as non-ionic and included in the chemical classification of alkyl polysaccharides, the most popular of this chemical group being the alkyl polyglycoside and commonly called apgs, in combination of a dispersant / film former based on polyvinylpyrrolidone, as well as the use of this agricultural adjuvant composition to increase the physical stability of spray mixes, the anti-drift power of spray mixes and the agronomic effectiveness of fungicidal contact formulations, among them the mancozeb, chlorothalonil and cupric fungicides (Bordeaux mixture or copper oxy sulfate, copper hydroxide, copper oxychloride and cuprous oxide). in addition to being compatible with various agrochemical formulations in mixtures in the spray tank, the adjuvant composition of this invention has been shown to be able to improve the stability and agronomic effectiveness of these formulations, as well as to physically-chemically make compatible several complex mixtures added to the spray tank, ensuring a better application of agrochemical products on crops and better use.
