    摘要: The present invention is aimed at providing a weed control method and a mixed agrochemical composition for soil treatment, which, in a soil treatment of farmland with pyroxasulfone, not only can inhibit or reduce crop injury caused by absorption into cultivated crops, without being influenced by heavy rainfall, soil type, seeding depth and the like, but also are effective against a wide range of weed species. The weed control method includes a soil treatment step of performing a soil treatment on farmland with an agrochemical composition for soil treatment, which contains pyroxasulfone, and with a protoporphyrinogen oxidase inhibitor, simultaneously or sequentially, the method being characterized in that the agrochemical composition for soil treatment further contains a masking substance that masks the pyroxasulfone, and the pyroxasulfone is microencapsulated in or coated with the masking substance. The mixed agrochemical composition for soil treatment is characterized by containing the agrochemical composition for soil treatment and a protoporphyrinogen oxidase inhibitor.

    摘要: Provided is a pyribencarb aqueous suspension agrochemical composition which contains an adjuvant for reinforcing the efficacy of pyribencarb, and which is capable of preventing a pharmaceutical preparation from becoming highly viscous or solidified and capable of providing a sufficient controlling effect with a small amount of pyribencarb. The aqueous suspension agrochemical composition includes: pyribencarb which is an agrochemically active component; an adjuvant for pyribencarb, which is one or more compounds selected from polyoxyalkylene siloxanes, polyoxyethylene/polyoxypropylene block copolymers, and polyoxyalkylene alkyl ethers; a nonionic-anionic surfactant which is a polyoxyalkylene aryl ether sulfuric acid salt and/or a polyoxyalkylene aryl ether phosphoric acid salt; and water.
