Description

ABSTRACT:
A herbicide composition containing propanil as active ingredient is now provided in the form of emulsifiable concentrated organic solution of propanil and surface-active agent(s) in non-toxic mixed organic solvents, which is readily dilutable with water to prepare a stable aqueous emulsion comprising the organic solution of propanil as the disperse phase dispersed in water as the continuous phase of the resulting aqueous emulsion without involving precipitation of propanil solids in said emulsion. Said mixed organic solvents may comprise a mixture of a glycol ether-type solvent with either one or two of dimethyl-sulfoxide and N-methyl-2-pyrrolidone, optionally along with an aromatic solvent. Also, a herbicide composition is provided in the form of a stable solution of propanil in non-toxic mixed organic solvents similar to those mentioned above, which is stable on storage and may be formulated into an emulsifiable concentrated organic solution of propanil by adding surface-active agent(s) thereinto.
