Hybrid herbicide containing Cinosulfuron, Bispyribac-sodium and cinmethylin and application of hybrid herbicide

Abstract

The invention discloses a hybrid herbicide containing Cinosulfuron, Bispyribac-sodium and cinmethylin. The herbicide takes the Cinosulfuron, the Bispyribac-sodium and the cinmethylin as main effective ingredients with the mass ratio of (0.1-80): (0.1-80): (0.1-80). The hybrid herbicide disclosed by the invention has obvious effect when being applied to the paddy field 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 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 ternary mixed compound of metursulfuron, bispyrifen and cyprofen. The herbicide composition can be applied to pre-emergence and Early weeding after budding. 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 food crop 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 the 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 h...

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
