HERBICIDAL COMPOSITION IN FORM OF OIL DISPERSION FOR WEED CONTROL Russian patent published in 2015 - IPC A01N43/48 A01N33/00 A01P13/00 

FIELD: agriculture.

SUBSTANCE: composition comprises active compounds, a nonionic surfactant, diluents, and a thickener. The active compounds are imazamox and chlorimuron-ethyl. The nonionic surfactant is a mixture of polyethylene glycol esters of fatty acids or alkoxylated fatty alcohols. The thickener is used as silica or bentonite. The diluent is vegetable oil. The mass concentration of the composition is following, g/l: imazamox 10-100, chlorimuron-ethyl 1-40, surfactant 100-400, thickener 10-30, vegetable oil - the rest up to 1 l.

EFFECT: increase in maximum wettability of leaf surface and more rapid and deep penetration of the preparation into the plant by creating oil dispersion with a dispersion of the active substance of not more than 3 micron, which enhances the biological efficacy of the preparation.
