Abstract

The invention discloses herbicide used for controlling Gramineae and broad-leaved weeds in a wheat field. The herbicide is binary herbicidal composition with clodinafop-propargyl and cyclosulfamuron being active ingredients. In the herbicidal composition, the weight ratio of clodinafop-propargyl to cyclosulfamuron is 3:32-24:1, and the mass percentage content of the herbicide is 5 percent-80 percent of compound herbicide. The herbicidal composition is used for controlling the weeds in the wheat field, the components are reasonable, the control effect on the weeds of the herbicidal composition is superior to the activity in the process of separately applying all the components, the weed control spectrum can be enlarged, control cost can be lowered, herbicide resistance of the weeds is relieved, and the herbicidal composition is safe for crops, does not have influence on the environment and meets the safety requirements of pesticide preparations.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide composition containing clodinafop-propargyl and cyprosulfuron-methyl, which is used for controlling gramineous and broad-leaved weeds in wheat fields. 【Background technique】 [0002] Wheat is an important food crop in my country with a large planting area. In recent years, due to changes in farmland ecosystems and enhancement of weed resistance, weeds in wheat fields have become the main hazards in wheat production. Chemical weeding is the main means of controlling weeds in agriculture, but the herbicides currently on the market cannot control all the weeds in the wheat field at the same time. A large amount of manpower and material resources, on the other hand, caused environmental pollution and excessive pesticide residues, which brought direct harm to human health. Moreover, due to long-term repeated or unscientific use of these chemicals, the resi...
