This invention relates to a high-strength herbicidal formulation containing high concentrations of glyphosate monomethylamine or dimethylamine salt and one or more surfactants selected to enhance the herbicidal activity of the glyphosate salts. The formulations exhibit significantly lower viscosity at high concentrations.

The invention relates to novel substituted benzoylcyclohexanediones of the general formula (I), in whichm, n, A, R1, R2, R3, R4 and Z are each as defined in the description,and also to processes for their preparation and to their use as herbicides.

The invention provides a compound herbicide composition. The compound herbicide composition is prepared from a first active ingredient, a second active ingredient and a third active ingredient, wherein the first active ingredient is penoxsulam; the second active ingredient is cyhalofop-butyl; the third active ingredient is 2-methyl-4-chlorophenoxy acetic acid or a derivative thereof; and the weight percent ratio of the three active ingredients is (0.1-40):(1-100):(1-100). The compound herbicide composition has the beneficial effects that by carrying out ternary compounding on the penoxsulam, cyhalofop-butyl and 2-methyl-4-chlorophenoxy acetic acid or the derivative thereof, the new composition is applied to controlling grassy weeds, broadleaf weeds and cyperaceae weeds in the rice fields, has an ideal control effect, especially has an obviously improved control effect on barnyard grass, rice weeds, xeromorphic polygonum amphibium, waterpepper, eclipta prostrate, ammannia arenarid H., crab grass, scirpus yagara, eleocharis acicularis, eleusine indica, monochoria korsakowii, paspalum distichum, moleplant seed, cyperus difformis, scirpus planiculmis and sagittaria trifolia, also can solve the problem of the dosage for controlling some novel weeds in the fields in which penoxsulam and cyhalofop-butyl are used perennially and has certain effects on rice production increase.
