Definitions
- the present invention relates to a herbicidal suspension concentrate comprising a specific sulfonamide compound(s) and/or a salt(s) thereof, a vegetable oil, and a surfactant at a specified ratio.
- This is a useful concentrate which can control a wide variety of harmful weeds without any phytotoxicity against corns when applied to corn fields.
- European Patent Laid-Open Nos. 232,067 and 237,292 both disclose that sulfonamide compounds and their salts, which are the active ingredients contained in the herbicidal suspension concentrate of the present invention, are useful as herbicides for application to corn fields. However, they fail to disclose that these compounds can be admixed with a vegetable oil and a surfactant, thereby to prepare a suspension concentrate.
- the present invention relates to a herbicidal suspension concentrate characterized by comprising from 0.5 to 20 parts by weight of at least one compound selected from among sulfonamide compounds represented by the general formula (I): ##STR2## (wherein X is a hydrogen atom, a chlorine atom, a bromine atom, a methyl group, or a difluoromethyl group) and their salts as an active ingredient, from 55 to 94.5 parts by weight of a vegetable oil, and from 5 to 25 parts by weight of a surfactant.
- sulfonamide compounds represented by the general formula (I): ##STR2## (wherein X is a hydrogen atom, a chlorine atom, a bromine atom, a methyl group, or a difluoromethyl group) and their salts as an active ingredient, from 55 to 94.5 parts by weight of a vegetable oil, and from 5 to 25 parts by weight of a surfactant.
- the suspension concentrate of the present invention when applied to a corn field, provides improved weeding effect against harmful weeds in general, and against gramineous weeds in particular, without any phytotoxicity against corns. As a result of this improvement, the spectra of the harmful weeds to be controlled are spread, and further the amount of the active ingredient compound to be used can be decreased.
- the sulfonamide compounds of the present invention represented by the general formula (I), and their salts are already known as herbicides for application to corn fields. In practical use of these compounds, however, it is still required to decrease the amount of the active ingredient compound to be used in view of the reduction of expenditure for weeding and the reduction of environmental contamination. While it is also required to control as perfectly as possible a variety of weeds differing in growth stage without any crop injury to corns.
- the authors of the present invention have found that use of a vegetable oil in the preparation of a suspension concentrate wherein the sulfonamide compound, represented by the general formula (I), or its salt is blended with the vegetable oil and a specific surfactant at a specific weight ratio can satisfy the requirements mentioned above when an aqueous diluted suspension prepared from the suspension concentrate is applied to a corn field. Namely they have found that use of the vegetable oil improves the weeding effect against broad spectra of the harmful weeds to be controlled without any phytotoxicity against corns and can decrease the amount of the active ingredient compound to be used, and that consequently reduction of environmental pollution can be expected.
- Examples of sulfonamide compounds which are represented by the general formula (I), and which therefore can be used in the present invention include N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-3-dimethylaminocarbonyl-2-pyridinesulfonamide, N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-6-chloro-3-dimethylaminocarbonyl-2-pyridinesulfonamide, N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-6-bromo-3-dimethylaminocarbonyl-2-pyridinesulfonamide, N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-3-dimethylaminocarbonyl-6-methyl-2-pyridinesulfonamide, and N-[(4,6-dimethoxypyrimidin-2-yl)amino
- salts of the above-mentioned sulfonamide compound include those of alkali metals such as sodium and potassium, those of alkali earth metals such as magnesium and calcium, and those of amines such as monomethylamine, dimethylamine and triethylamine, specific examples of which include sodium and monomethylamine salts of N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-3-dimethylaminocarbonyl-2-pyridinesulfonamide, and dimethylamine salt of N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-3-dimethylaminocarbonyl-6-methyl-2-pyridinesulfonamide.
- N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-3-dimethylaminocarbonyl-2-pyridinesulfonamide and its salts are exemplified as preferred compounds.
- corn oil is particularly preferred.
- any surfactant may be used as long as it can emulsify the above-mentioned vegetable oils in water.
- surfactants include those of vegetable oil derivatives such as polyoxyethylene hydrogenated castor oil ether; nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene (propylene)fatty acid esters, sorbitan monooleate, and polyoxyethylene sorbitan monolaurate; and anionic surfactants such as sodium alkylarylsulfonates, sodium dialkylsuccinate sodium dialkylsulfosuccinates, polyoxyethylene alkylaryl ether sulfates, polyoxyethylene alkyl phosphates, polyoxyethylene alkylaryl phosphates, and sodium alkylnaphthalenesulfonates.
- vegetable oil derivatives such as polyoxyethylene hydrogenated castor oil ether
- nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene (propylene)fatty acid esters, sorbitan monooleate, and polyoxy
- a mixture of a surfactant of vegetable oil derivatives, a nonionic surfactant and an anionic surfactant is preferably used.
- the suspension concentrate of the present invention is prepared, for example, according to the following procedure.
- At least one compound selected from among the sulfonamide compounds represented by the aforementioned general formula (I) and their salts as an active ingredient compound(s) is uniformly mixed with a vegetable oil and a surfactant and the resulting mixture is ground in order to obtain a suspension concentrate.
- an active ingredient compound(s) preliminarily ground is merely mixed with a vegetable oil and a surfactant to obtain a suspension concentrate.
- a thixotropic material(s) such as a bentonite-alkylamine complex(es) and/or aerosil may be added in an amount of, for example, 1 to 3 weight % based on the total concentrate if necessary.
