To provide a method for managing a lawn at a site, such as a golf course, where turfgrass less sensitive to herbicides and turfgrass highly sensitive to herbicides are used in combination, without causing undesirable effects on the highly sensitive turfgrass. A herbicidal compound and a silicone surfactant are applied to a site where turfgrass less sensitive to the herbicidal compound is planted, thereby to reduce undesirable effects on nearby turfgrass highly sensitive to the herbicidal compound.

Method for reducing undesirable effects on turfgrass

Improvement of the effect of a herbicidally active ingredient and reduction of its dosage are required so as to reduce the environment load on a site where the herbicide is applied or the periphery thereof, more than ever. A herbicidal composition comprising (1) a herbicidal sulfonylurea compound or its salt and (2) a polyoxyalkylene alkyl ether phosphate or its salt. A method for controlling undesired plants or inhibiting their growth, by applying such a herbicidal composition.

Herbicidal composition

A herbicidal composition comprising a herbicidal sulfonylurea compound or its salt, and an alkoxylated glyceride. A method for controlling undesired plants or inhibiting their growth, which comprises applying a herbicidally effective amount of the herbicidal composition to the undesired plants or to a place where they grow. A method for enhancing the herbicidal effect of a herbicidal sulfonylurea compound or its salt by means of an alkoxylated glyceride.

Herbicidal composition having the herbicidal effect enhanced, and method for enhancing the herbicidal effect

A herbicidal suspension comprising (1) a sulfonylurea compound or its salt as a herbicidal component, (2) at least one surfactant selected from the group consisting of an alkoxylated sorbitol fatty acid ester and an alkoxylated sorbitan fatty acid ester, and (3) a water-immiscible diluent. A method for controlling undesired plants or inhibiting their growth, which comprises applying a herbicidally effective amount of the herbicidal suspension to the undesired plants or to a place where they grow.

Herbicidal suspension

A herbicidal composition is disclosed, comprising, as active ingredients, 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridylsulfonyl)ure a and an isopropylamine salt or trimethylsulfonium salt of N-(phosphonomethyl)glycine.

Herbicidal composition comprising glyphosate and

A herbicidal composition is disclosed, comprising, as active ingredients, 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridylsulfonyl)ure a and an ammoium salf of homoalanin-4-yl(methyl)phosphinic acid.
