Herbicidal compositions and methods.

摘要

The growth and reproduction of many undesirable grass weeds in association with broadleaf weeds in cereal and legume crops can be selectively controlled and/or inhibited by applying to the said weedy grasses or broadleaf plants or plant parts or soil the novel herbicide composition which is comprised of 1 part by weight active ingredient of methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propionate and either (a) from 0.5 to 2 parts by weight active ingredient of (4-chloro-2-methylphenoxy) butyric acid (MCPB), or an ester or oil-soluble amine salt thereof, or (b) from 0.3 to 3 parts by weight active ingredient of a herbicidal compound mixture containing (1) 1 part by weight of 4-(4-chloro-2-methylphenoxy) butyric acid, or an ester or oil-soluble amine salt thereof, and (II) from 0.75 to 1.5 parts by weight of a hydroxybenzonitrile compound selected from 3,5-dibromo-4-hydroxy benzonitrile, 4-hydroxy-3,5-diiodobenzonitrile, and esters thereof.
