Embodiment 2

[0106] Formulation Example 2 (extrusion granules)

[0107] To the compound (a) of 3 parts by weight, the compound (b-2) of 0.1 part by weight, the sodium bentonite (montmorillonite) of 30 parts by weight, the sodium hexametaphosphate of 2 parts by weight and the clay of 60.2 parts by weight 22 parts by weight of water comprising 0.2 parts by weight of dialkyl sulfosuccinic acid sodium salt, 4 parts by weight of polyoxyalkylene tristyryl phenyl ether sulfate sodium salt and 0.5 parts by weight of polycarboxylic acid sodium salt and fully The resulting mixture was kneaded, processed into 500 to 1700 µm granules with an extrusion type granulator, and dried at 80°C to obtain granules.

Embodiment 3

[0108] Formulation Example 3 (fine granules)

[0109] 73.2 parts by weight of clay mineral particles having a particle size distribution of 0.2 to 0.7 mm were charged into a container rotary type agitator, and 15 parts by weight of compound (a) and 0.3 parts by weight of compound (b-2) were mixed with 10 parts by weight of liquid diluent are sprayed together, and 1.5 parts by weight of white carbon are added to obtain fine granules.

Abstract

A herbicidal composition with reduced phytotoxicity, containing, as a combination, (a) 2-{2-chloro-4-mesyl-3- [(tetrahydrofuran-2-ylmethoxy)methyl] benzoyl}- cyclohexan-1, 3-dione; and (b) at least one phytotoxicity-reducing substance selected from the group consisting of benzoisothiazolinone derivatives, benzamide derivatives, benzothiazole derivatives, benzoxazolinone derivatives, benzoxazine derivatives, thiazinyl, isoprothiolane, hexamethylenetetramine, potassium oxalate and vanillin derivatives.

Description

technical field [0001] The present invention relates to herbicidal compositions with reduced phytotoxicity. More specifically, the present invention relates to a herbicidal composition with reduced phytotoxicity, comprising a compound having herbicidal activity and a specific compound having a phytotoxicity-reducing effect. Background technique [0002] Herbicidal benzoylcyclohexanediones are known in several documents (eg WO 98 / 29406, WO 00 / 21924, WO 01 / 07422 and WO 2004 / 063187). [0003] In addition, 2-{2-chloro-4-methanesulfonyl-3-[(tetrahydrofuran-2-ylmethoxy)-methyl]benzoyl}-cyclohexane-1,3-dione (common name: Tefuryltrione (abbreviated as tefuryltrione) is a kind of benzoylcyclohexanedione, which has superior herbicidal activity, but depends on the conditions of use, application stage, application rate, target crop plants, etc. Crop plants relatively pose problems of phytotoxicity. Therefore, it is desired to study and find compounds having a phytotoxicity-reducing ...
