A herbicidal composition for upland farming which can control weeds that have been difficult to control, for example, cleavers, chickweed, birdseye speedwell and violet, said composition containing as active ingredients a 3-substituted phenylpyrazole derivative represented by the general formula (I): ##STR1## (wherein R is a hydrogen atom, a C.sub.1-6 alkyl group, a C.sub.3-6 cycloalkyl group, a C.sub.1-6 haloalkyl group, a C.sub.2-6 alkenyl group or a C.sub.2-6 alkynyl group, R.sup.1 is a C.sub.1-6 alkyl group, X.sup.1 and X.sup.2, which may be the same or different, are halogen atoms, and Y is an oxygen atom or a sulfur atom) and at least one compound selected from the group consisting of sulfonylurea derivatives, phenylurea derivatives and phenoxy fatty acid derivatives; and a weeding method using said composition.

Herbicidal composition for upland farming and weeding method

The present invention discloses phenylimidazole derivatives having herbicidal activities, represented by general formula (I) ##STR1## (R.sup.1 and R.sup.2 each represent an alkyl group or the like; R.sup.3 represents an alkoxy group or the like; X is a hydrogen atom or a halogen atom; and two Ys each represent a halogen atom); processes for producing said derivatives; herbicidal compositions each comprising said derivative as an active ingredient; and a method for weed control, using said herbicidal composition.

Phenylimidazole derivatives, herbicides comprising said derivatives, and

A pesticidal aqueous suspension concentrate containing as an active ingredient a 3-substituted pyrazole derivative represented by the general formula (I): ##STR1## (wherein the substituents areas defined in the description of the specification)in which the 50% particle size and 90% particle size in cumulative particle size distribution of particles of the active ingredient are less than 1 .mu.m and less than 2 .mu.m, respectively, and which is harmless to useful crops and is equal to an emulsifiable concentrate in herbicidal effect; and a process for producing said pesticidal aqueous suspension concentrate.
