A kind of synergistic herbicide composition

Abstract

The invention discloses a synergism weeding composition. The synergism weeding composition comprises 2-(6-fluorine-2-pyridine acyloxy)-N-(4-fluorophenyl)-N-(1-methyl ethyl) thioacetamide ((b)TAM-5( / b)) and tebuthiuron which serve as the effective components and auxiliary components acceptable in pesticide, wherein the weight ratio of TAM-5 to the tebuthiuron is 40:1-1:60. The synergism weeding composition has the advantages that the two effective components are combined to form synergism, the herbicide controlling spectrum can be expanded, antagonism is avoided, and safety to crop is increased; the synergism weeding composition is applicable to weeding of farmland such as corn fields, sugar cane fields, rape fields and tea gardens and non-farmland and capable of evidently increasing weeding effect and lowering cost; when the synergism weeding composition is applied to the sugar cane fields for selective weeding, good weeding effect is achieved, chemical damage to sugar canes is avoided, and the synergism weeding composition is especially suitable for the selective weeding of the sugar cane fields.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, which is especially used for weeding in sugarcane fields, corn fields, rapeseed fields, tea gardens and other farmlands and non-cultivated lands. Background technique [0002] There are many weeds in sugarcane fields, corn fields, rapeseed fields, tea gardens and other farmlands and non-cultivated lands. Take common cornfield weeds as an example, including barnyardgrass, crabgrass, velvet hemp, amaranth, goosegrass, teff, green foxtail, golden foxtail and so on. Common weeds in sugarcane fields include Cyperus cyperi, crabgrass, goosegrass, bald barnyardgrass, ghost needle grass, bermudagrass and other annual weeds. Among the common weeds in cornfields, there are not only annual weeds but also perennial weeds, and these weeds have multiple grassing periods, so it is difficult to control. At present, glyphosate, glufosinate, acetochlor, and bikgrass, which are most commonly used in agricultu...

AI Technical Summary

Problems solved by technology

However, when these thioacetamide compounds are prepared into preparations and used alone, there are still shortcomings such as insufficient herbicidal spectrum and high age requirements for certain weeds.
