Provided is an agrochemical composition for foliage treatment, which does not cause phytotoxicity to a cultivated crop due to adhesion thereto when foliage treatment of an upland field is performed with pyroxasulfone, but has a high level of safety and an herbicidal effect on a broad spectrum of weeds. The agrochemical composition for foliage treatment comprises pyroxasulfone and a masking material that masks the pyroxasulfone, wherein the pyroxasulfone is microencapsulated in or coated with the masking material such that phytotoxicity to a cultivated crop due to adhesion thereto when foliage spraying is performed is avoided.

Agrochemical composition for foliage treatment

Provided is a herbicidal composition comprising a herbicidally active compound selected from a difluoromethanesulfonylanilide compound represented by the general formula (I): wherein Rrepresents a hydrogen atom, an alkyl group or an alkoxyalkyl group; or a salt thereof encapsulated in a microcapsule, or a herbicidal composition comprising the herbicidally active compound encapsulated in a microcapsule and a benzoic acid compound represented by the general formula (II): wherein Rrepresents a hydrogen atom, an alkyl group having 1 to 15 carbon atoms, a hydroxyl group, a nitro group, or an amino group; and Rrepresents a hydrogen atom, an alkali metal atom or an alkyl group. The herbicidal composition exert a pharmacological effect for a prolonged period of time, can alleviate or prevent any harmful effect and can reduce the environmental load.

Herbicidal composition

Disclosed is a technique for achieving a required herbicidal effect using a small amount of a herbicide. Specifically disclosed are: a granular fertilizer containing a herbicidal agrochemical, which is characterized in that the granular fertilizer has been impregnated or coated with pyroxasulfone; and a weed eradication method which is characterized by applying the granular fertilizer to fields.

Granular fertilizer containing herbicidal agrochemical

It is intended to provide a phytotoxicity controlling agent usable as a herbicide for upland farming, which exerts a sufficient herbicidal effect on weeds growing together with upland crops, for example, wheat, rye, barley, oat, corn, sorghum, cotton, soybean, adzuki bean, oilseed rape, beet, upland rice and so on but causes no phytotoxic phenomenon (for example, growth inhibition, growth suppression, tiller inhibition or yellowing) in cultivated plants, comprising a nuclear-substituted benzoic acid represented by the following general formula: wherein Rrepresents linear or branched Calkyl; a salt thereof or an alkyl ester thereof.

Phytotoxicity controlling agent for upland farming and phytotoxicity controlling method using the same

A mixed composition for weeding useful as a herbicide which is effective against a wide spectrum of weeds, is highly active, has excellent residual activity, and is highly safe for useful plants. It is characterized by containing as an active ingredient a combination of (A) a compound selected among a difluoromethanesulfonylanilide compound represented by the general formula (I): (wherein Ris hydrogen, Calkyl, or Calkoxyalkyl) and salts of the compound and (B) at least one member selected among herbicidal aromatic-ring-containing compounds, e.g., indanofan, and herbicidal nitrogenous heterocyclic compounds, e.g., TH-547, nicosulfuron, Flutiacet-methyl, and atrazine.

Composition for weeding

A herbicide composition contains, as a component A, one or more compounds selected from the group consisting of specific isoxazoline derivatives represented by the general formula [I] (wherein Rto Rrepresent each a hydrogen atom, an alkyl group, etc.; and Q represents &#x2014;S(O)n&#x2014;(CRR)m&#x2014;, wherein n is an integer of 0 to 2, m is an integer of 1 to 3, and Rand Rrepresents each an alkyl group, etc.) and salts thereof; and, as a component B, a cyclohexanedione type compound, a phenylpyrazoline type compound or a sulfonyl aminocarbonyl triazine type compound and the like; as the active ingredients.

Herbicide composition

An agricultural chemical composition which enables a wide range of herbicidal compounds including ones showing phytotoxicity to crop plants, etc. upon mere application to exhibit a sufficient herbicidal effect and to show reduced or no phytotoxicity to the crop plants. The agricultural chemical composition comprises (A) a herbicidal compound selected from the group consisting of sulfonylurea compounds, sulfonamide compounds, chloroacetanilide compounds, thiocarbamate compounds, pyrimidinyloxy(thio)benzoic acid compounds, tetrazolinone compounds, pyrazole compounds, cyclohexanedione compounds, phenoxycarboxylic acid compounds, oxazinone compounds, and difluoromethanesulfonylanilide compounds or salts thereof and (B) a compound selected among benzoic acid compounds.

Agricultural chemical composition

A plant growth regulator composition comprising a cyclohexane derivative of the formula: ##STR1## wherein R is a hydrogen atom, a lower alkyl group, an alkylthioalkyl group, a phenyl group or a substituted phenyl group, and R.sup.1 is a lower alkyl group, a cycloalkyl group, a benzyl group, a substituted benzyl group, a phenethyl group, a phenoxymethyl group, a 2-thienylmethyl group, an alkoxymethyl group or an alkylthiomethyl group, or a salt thereof, and a nitrogen-containing water-soluble inorganic substance or urea.
