HERBICIDAL COMPOSITION AND METHOD FOR CONTROLLING OF UNDESIRABLE PLANTS Russian patent published in 2006 - IPC A01N43/40 A01N43/42 A01N25/22 A01N25/04 A01N25/32 A01P13/00 

FIELD: agriculture, organic chemistry.

SUBSTANCE: invention relates to herbicidal composition in form of aqueous emulsion containing a) as organic phase: 5-25 mass % of herbicidally effective amount of 2-(4-(3-chloro-5-fluoro-2-pyridyloxy)-phenoxypropionic acid propargyl eater (component A); 1-6 mass % of 2-(5-chloroquinoline-8-yl-oxy)-acetic acid 1-methylhexyl ester (component B) in amount effective to counteract to herbicide; 10-60 mass % of hydrophobic solvent; 0.5-25 mass % of essentially water insoluble hydrolysis-resistant emulsion stabilizer; and b) as aqueous phase: 0.5-5 mass % of at least one surfactant and/or dispersant, and balance: water buffered with acid and salt mixture in amount of 0.1-1 mol adjusting pH value 4-6. Also disclosed is method for controlling of undesirable plants by application of composition in herbicidally effective amount on plant or growth region thereof.

EFFECT: increased herbicidal activity of component A; stable drop emulsion; high cold stability.
