2,3-DICHLORO-4-[(6-CHLORO-5-CYANO-4-METHYLPYRIDYL-2)-METHYLHYDRAZONO]-BUTEN-2-OIC ACID AS ANTIDOTE 2,4-D ON SUNFLOWER Russian patent published in 2011 - IPC C07D213/84 A01N25/32 A01P13/00

Abstract RU 2426719 C2

FIELD: chemistry.

SUBSTANCE: invention relates to novel biologically active chemical substances. The proposed substance which reduces the negative effect of the 2,4-dichlorophenoxy acetic acid herbicide on sunflower plants is 2,3-dichloro-4-[(6-chloro-5-cyano-4-methylpyridyl-2)-methylhydrazono]-buten-2-oic acid. The technical result is achieved by using 2,3-dichloro-4-[(6-chloro-5-cyano-4-methylpyridyl-2)-methylhydrazono]-buten-2-oic acid to treat damaged sunflower plants a day after applying the herbicide.

EFFECT: wider range of synthetic biologically active substances for use in agriculture as 2,4-D antidotes.
