Problems solved by technology

[0011] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention belongs to the technical field of agricultural chemicals and discloses a mixed herbicide containing cinosulfuron and propanil and an application thereof. The herbicide takes the cinosulfuron and the propanil as main active ingredients, the mass ratio of the cinosulfuron to the propanil is (0.1-80):(0.1-80), and the content in percentage by weight of the cinosulfuron and the propanil in the mixed 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 etesulfuron-methyl and propannil and an application thereof. Background technique [0002] China is the country with the longest history of rice cultivation in the world. Rice is one of the main grain crops in my country, with a planting area of ​​about 33 million hectares, accounting for about 29% of the grain crop planting area. The northernmost limit of rice growth in China is Huma, Heilongjiang Province, China. But the main growing area is the south, Taiwan, and rice is also grown in the north along the river. That is, rice grows almost everywhere. [0003] It is reported that rice all over the country is damaged by weeds in different degrees every year. If weeding is not done in the field, rice yield can be reduced by more than 50%. The main harmful weeds in paddy fields are: barnyardgrass, daughter, reed, firefly...
