FIELD: organic chemistry, herbicides.
SUBSTANCE: invention describes using 2-(3-nitrophenyl)-4,4-dipgenyl-1,2-dihydro-4H-3,1-benzoxazine of the formula (III) 
2-(3-nitro-2-bromophenyl)-4,4-dimethyl-1,2-dihydro-4H-3,1-benzoxazine of the formula (IV) 
2-(5-methylfur-2-yl)-4,4-dimethyl-1,2-dihydro-4H-3,1-benzoxazine of the formula (V) 
as antidotes of herbicide 2,4-dichlorophenoxyacetic acid that exert the hormonal effect for protection of sunflower seedlings. Invention provides expanding spectrum in using the known compounds among substituted 1,2-dihydro-4H-3,1-benzoxazines, namely, their using as antidotes providing decrease of negative effect of herbicide with hormonal effect for protection of sunflower.
EFFECT: valuable properties of compounds.
