Abstract

The invention belongs to the technical field of agricultural chemicals and discloses a mixed herbicide containing cinosulfuron and bispyribac-sodium and an application thereof. The mixed herbicide takes the cinosulfuron and the bispyribac-sodium as main active ingredients, the mass ratio of the cinosulfuron to the bispyribac-sodium is (0.1-80):(0.1-80), and the content in percentage by weight of the cinosulfuron and the bispyribac-sodium in the herbicide is 1-85%. The mixed herbicide disclosed by the invention has significant effects in applications in post-emergence weeding of rice paddy fields, in particular to the applications in control of various grass family, sedge family and broadleaf weeds in the rice paddy fields. Compared with a single agent, the herbicide disclosed by the invention can delay weed resistance and realize the advantages of broad weed control spectrum, long lasting period and safety against rice and afterreap crops on the premise of improving efficacy.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to a herbicide, in particular to a mixed herbicide containing difenosulfuron and bispyripyr and its application. Background technique [0002] China is the country with the longest history of rice cultivation in the world. Rice is one of my country's main food crops. The planting area is about 33 million hectares, accounting for about 29% of the grain crops planting area. The northernmost limit of rice growth in China is Huma, Heilongjiang Province, China. But the main growing areas are the south and Taiwan, and rice is also grown in the north along the river. In other words, rice grows in almost most places. [0003] It is reported that every year rice in the country suffers from different degrees of weed damage. If weeds are not weeded in the field, rice yield can be reduced by more than 50%. The main harmful weeds in rice fields are: barnyard grass, stephengrass, reeds, firefly, wat...
