Abstract

The invention is to provide a weeding combination with a wide weed control spectrum, high activity and lasting effect. Active principles of the weeding combination provided by the invention are Alpha and Beta. Alpha is a compound or a salt thereof expressed by the formula (I); in the formula, R is a hydrogen atom or -COCH2OCH3. Beta is at least one compound selected from: at least one sulfonylurea compound selected from (B1.1) Bensulfuron-Methyl, (B1.2) azimsulfuron and so on; (B2.1) pyriminobac-methyl; (B3.1) an acetamide compound such as Pretilachlor; at least one benzoyl compound selected from (B4.1) benzobicylon, (B4.2) mesotrione and so on; (B5.1) a simetryne and so on.

Description

Technical field [0001] The present invention relates to at least one compound represented by (α) {the compound represented by the formula (I) described below or a salt thereof} and (β) selected from the group consisting of {compounds (B), (C) and (D) described below} Herbicidal composition with active ingredients. It also relates to a method of reducing undesirable effects of (α) {the compound represented by the formula (I) described below or a salt thereof} on useful crops, etc. Background technique [0002] In recent years, people have frequently used so-called selective herbicides that have both safety on useful crops and herbicidal effects on undesirable plants. However, even highly selective herbicides are subject to different weather conditions and soil conditions during use. Various conditions such as crop variety, pesticide treatment period, etc. may sometimes cause phytotoxicity. The use of various phytotoxicity reducing agents to cope with such an undesirable sit...
