Abstract

The present invention relates to a herbicide composition, in particular to a cornfield herbicide combination with fenflumezone, chlorpyrazosulfuron-methyl, and amethazine or simazine selected from triazine herbicides as active ingredients In the composition, the weight ratio of the active ingredients fenflumezone, chlorpyrazosulfuron-methyl and triazine herbicides is (0.375‑6): (0.5‑8): (30‑480), and the active ingredients are combined The weight percentage in the product is 10-80%. The compound herbicide can be prepared into conventional dosage forms such as wettable powder, water dispersible granule, suspension concentrate, etc. The herbicide composition of the present invention can prevent and eliminate various weeds in the cornfield at the same time, and significantly improves the weed control effect on the cornfield. It is an ideal herbicide with high control effect, low dosage of active ingredients, low cost of use, and safety to corn and subsequent crops.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide composition containing fenflumezone, which is used for controlling weeds in cornfields. 【Background technique】 [0002] Corn is not only an important food crop in my country, but also an important feed crop and industrial raw material. With the development of animal husbandry, food processing industry, wine making industry and biodiesel industry, the market demand for corn continues to increase. Weeds in cornfields are common and of various types. Common weeds in cornfields in my country include crabgrass, goosegrass, barnyardgrass, foxtail, amaranth, purslane, quinoa, amaranth, velvetleaf, Cyperus cyperi, etc. When maize at the seedling stage is harmed by weeds, the plants will be short and the stems will be thin and the leaves will be yellow, which will lead to poor growth of maize in the middle and late stages and severe production reduction.
