Embodiment 1

[0120] To the mixture of 0.5 parts by weight of active compound (a-4), 3 parts by weight of active compound (b-7), 33.5 parts by weight of bentonite (montmorillonite), 60 parts by weight of talc and 3 parts by weight of lignosulfonate 25 parts by weight of water, and then the resulting mixture is fully kneaded and passed through an extrusion granulator to prepare 10-40 mesh granules, which are then dried at 40-50° C. to obtain granules.

Embodiment 2

[0122] 96.5 parts by weight of clay mineral particles having a particle size distribution of 0.2-2 mm were fed into a rotary mixer and sprayed with 0.5 parts by weight of active compound (a-4) and 3 parts by weight of active compound (b-6) under rotation. Diluent The resulting mixture is uniformly wetted and dried at 40-50° C. to obtain granules.

Embodiment 3

[0124] With 0.5 parts by weight of active compound (a-4) and 3.5 parts by weight of active compound (b-1), 10 parts by weight of ethylene glycol, 3 parts by weight of polyoxyalkylene tristyryl phenyl ether, 10 parts by weight of xanthan gum, A mixture of 0.5 parts by weight of 14% silicone oil emulsion and 72.5 parts by weight of water was thoroughly stirred, and then pulverized with a crusher (DYNO-MILL, KDL type) to obtain an aqueous suspension.

Abstract

Mixed herbicidal compositions for controlling weeds, preferably in paddy field are provided. The compositions are characterized by comprising, as active ingredients, (a) an herbicidal difluoromethane sulfonamide, (b) at least one herbicidal compound selected from the group consisting of known herbicides as defined in claim 1 and, optionally, (c) one or more compounds selected from the group consisting of safeners.

Description

technical field [0001] The present invention relates to mixed herbicidal compositions for controlling weeds, preferably for controlling weeds in crops of useful plants, for example cereal crops such as rice, wheat, barley, rye, oats, corn, millet and plantation crops, Preference is given to paddy field crops, as in paddy fields. More preferably, the present invention relates to a mixed herbicidal composition for use in paddy fields, comprising a herbicidal difluoromethane N-sulfonanilide and a known herbicidal compound as active ingredients. Background technique [0002] Certain difluoromethane N-sulfonanilides are known to show good weed control effects on lowland weeds (WO 2005 / 096818, Japanese Patent Application Laid-Open No. 2006-56870). However, contrary to our expectations, when they are actually used, they may sometimes show insufficient herbicidal effects and phytotoxicity to rice is also observed. For practical application, since there are many potential factors a...
