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 pesticide, disclosing a hybrid herbicide containing Cinosulfuron, Bispyribac-sodium and butachlor and an application of the hybrid herbicide. The hybrid herbicide takes the Cinosulfuron, the Bispyribac-sodium and the butachlor as main effective ingredients with the mass ratio of (0.1-80): (0.1-90): (0.1-90). The hybrid herbicide disclosed by the invention has obvious effect when being applied to the paddy field pre-weeding, in particular to preventing and removing of various grass family weeds, cyperaceae weed family weeds and broad leaf family weeds in the paddy field. On the premise of improving pesticide effect, the hybrid herbicide can delay weed resistance, has the advantages of wide weeding spectrum and long effect lasting period if being compared with a single agent and is safe to the paddy and next batch of crop.

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, bispyriben and butachlor 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 and ...
