FIELD: agriculture.
SUBSTANCE: invention relates to the field of agriculture, namely to a method for improving the compatibility of a water soluble herbicide solution, a water soluble herbicide solution and a dry herbicidal composition. Such method comprises adding to the water soluble solution herbicide one or more surface-active agents that improve compatibility. Said surfactant is a polyacrylate or polymethacrylate grafted with polyethylene oxide side chains, a polymeric amphoteric dispersing agent, a sulfonated lignin or mixtures thereof. Above water soluble herbicide solution, having improved compatibility, contains at least one of the following: a water-soluble aryloxyalkanecarboxylic acid salt, a water soluble pyridyloxyalkanecarboxylic acid salt and a water soluble glyphosate salt, and one or more of the above surfactants that improve compatibility. Above dry herbicidal composition comprises a water soluble 2,4-D salt and / or a water soluble glyphosate salt and one or more of the above surfactants improving compatibility.
EFFECT: invention makes it possible to maintain the homogeneity of water soluble herbicide solutions by suppressing the formation of solids or phase separation, providing compatibility without the need to increase the pH level of the solution.
