Compound herbicide containing haloxyfop-R-methyl, bentazone and imazapic and application of compound herbicide

Abstract

The invention discloses a compound herbicide containing haloxyfop-R-methyl, bentazone and imazapic and application of the compound herbicide. The principle active ingredients of the compound herbicide are haloxyfop-R-methyl, bentazone and imazapic in the mass ratio of (1-18):(2-22):(3-5), and the mass percent contents of the three ingredients in the compound herbicide are 15-50%. The compound herbicide containing haloxyfop-R-methyl, bentazone and imazapic has a remarkable effect in application in peanut field weeding after seedling, in particular in application in prevention and weeding of various gramineous weeds and broadleaf weeds in the peanut field. Compared with single dosage, the compound herbicide containing haloxyfop-R-methyl, bentazone and imazapic has the advantages of weed resistance delaying, weeding spectrum expanding, both gramineous weed and broadleaf weed eliminating, long period of preserving heat, and reliable safety on either peanut or after-reap crops on the premise of improvement of pesticide effect.

Description

technical field [0001] The invention belongs to the field of herbicides and relates to a compound herbicide containing high-efficiency haloxyfop-pylene, bentazone and imazethapyr and an application thereof. Background technique [0002] Haloxyfop-P-methyl, molecular formula C 16 h 13 CIF 3 NO 4 , chemical name: 2-[4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenoxy]propanoic acid; 2-[4-(5-trifluoromethyl-3-chloro - methyl pyridine-2-oxy)phenoxy]propionate. [0003] High-efficiency haloxyfop-pyl can be quickly absorbed by the leaves of grass weeds after application, and spread to the whole plant, inhibiting the growth of plant meristems, thereby killing weeds. It has a long-lasting effect and has a good control effect on annual and perennial grass weeds from emergence to tillering and early heading. Highly safe to various broad-leaved crops under normal use. It can still show excellent herbicidal effect under low temperature and drought conditions. [0004] Bentazone, ...

AI Technical Summary

Problems solved by technology

But because imazethapyr is based on root suction, it is difficult to completely kill weeds when the density of weeds is high, or when the weed plants are large, and because the promotion time has been long, many weeds have already produced it. resistance

[0008] At present, herbicides in peanut fields are limited by crop safety, and their herbicidal spectrum is also limited. Using a herbicide alone can no longer completely and effectively control the occurrence of weeds in peanut fields.

Therefore, compound herbicides have become a hot research topic nowadays, but there is no relevant report on the compounding of the above three herbicidal compounds
