Weeding composition and special herbicide for nursery hedge

Abstract

The invention relates to the technical field of herbicides, and in particular relates to a weeding composition and a special herbicide for a nursery hedge. The weeding composition is composed of threeeffective components A, B and C, A is oxyfluorfen, B is any one of pendimethalin, metolachlor and S-metolachlor; and C is any one of quizalofop-p-ethyl, high-efficiency fluazifop-butyl, fluazifop-p-butyl and clethodim; and the weight ratio of A, B and C is (0.1-90) : (0.1-90): (0.1-90). The compound A, the compound B and the compound C are compounded, and the co-toxicity coefficient of the weeding composition is 120, the weeding composition has a synergistic effect; and the weeding composition is good in prevention and treatment effects and fast in effectiveness, the weeds can be killed thoroughly, the gramineous and broad-leaf weeds can be removed, the use amount of the pesticides can be reduced, the drug resistance of weeds can be delayed, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition and a special herbicide for nursery hedges. Background technique [0002] A nursery is a base for breeding and cultivating seedlings. Its task is to use advanced science and technology to cultivate high-quality seedlings of various types, specifications and purposes in a short period of time and at a low cost according to market demand, so as to meet the needs of urban and rural greening. Hedgerows are densely planted by shrubs or small trees with a close row spacing, planted in single or double rows, and closely combined in a regular planting form. Because of the selected tree species, it can be trimmed into various shapes and combined with each other, thus improving the ornamental effect and artistic value; in addition, the hedge can also play the role of covering bad viewpoints, isolating protection, preventing dust and noise, and guiding tourists t...

AI Technical Summary

Problems solved by technology

Therefore, the sales of pesticides and fertilizers, ancillary products related to the production of seedlings, nurseries, and hedges, are also increasing year by year. In particular, there is a great demand for herbicides for seedlings. However, there are relatively few special-effect herbicides for seedlings in China, and ordinary herbicides for field crops are usually used. For weeding, the weeding effect is poor, the efficiency is low, and the cost is high

There is no report on ternary compound herbicides for nurseries and hedgerows
