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...
