Problems solved by technology

[0014] 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 agents, and discloses a mixed herbicide containing cinosulfuron, butachlor and cinmethylin and application thereof, wherein the herbicide takes the cinosulfuron, the butachlor and the cinmethylin as main active ingredients, and the mass ratio of the cinosulfuron, the butachlor and the cinmethylin is 0.1-80/0.1-80/0.1-80. The mixed herbicide is applied to weeding paddy field, and particularly has the obvious effect on the application in preventing and weeding weeds of various grass families, sedge families or broad leaves in the paddy field. Compared with a single herbicide, under the premise of improving the efficacy, the mixed herbicide also has the advantages of weakened herbicide resistance, wide weeding scope and long efficacy duration, and is safe to paddy and succeeding crops.

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, butachlor and ciprofen 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. [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, water sedge, special-shaped sedge, broken rice sedge, sunshine sedge, eye vegetable, snakehead sausage, wild arrowhead mushroom, and duck tongue grass Wait. In order to reduce the economic loss caused by weed damage...
