Problems solved by technology

[0003] At present, because there is no suitable special herbicide for artificial planting of Polygonum viburnum, it has caused great difficulties to the cultivation of Polygonum viburnum.
With the existing herbicides on the market, due to the limited herbicidal spectrum, the occurrence of weeds in the planting of Polygonum viburnum cannot be completely and effectively controlled; more importantly, most of the herbicides on the market will cause serious damage to the Polygonum viburnum seedlings themselves. Harm, affecting its later growth

Abstract

The invention belonging to the technical field of polygonum viviparum planting, particularly discloses a herbicide composition for polygonum viviparum, and further discloses a herbicide preparation prepared from the herbicide composition. The effective components of the herbicide composition provided by the invention comprise lactofen, imazethapyr and quizalofop-p-ethyl. By compounding the three effective components, namely the lactofen, the imazethapyr and the quizalofop-p-ethyl, the prepared herbicide preparation can be used for safely and efficiently preventing and killing broad-leaved weeds and gramineous weeds in a polygonum viviparum planting field. The herbicide composition provided by the invention has the advantages of high efficiency, safety and a wide herbicide controlling spectrum, and obviously exceeds the use effect of a single component selected from the three effective components. The herbicide composition is safe to growing polygonum viviparum plants, low in cost and good in weed prevention effect.

Description

technical field [0001] The invention relates to the technical field of Polygonum viburnum planting, further relates to the weeding technology of Polygonum viniformis, in particular to a post-emergence herbicide of Polygonum viniformis. Background technique [0002] Polygonum viburnum is a plant of the genus Polygonum in the family Polygonaceae, a perennial herb. Wild Polygonum viburnum mainly grows in the alpine meadow area at an altitude of 2500-5000m. The plateau's unique topographical structure, complex geographical conditions and diverse climate characteristics make it a concentrated distribution area of ​​Polygonum viburnum. At present, with the wild excavation of Polygonum viburnum, its wild resources have been seriously scarce, and wild excavation has also caused great damage to the plateau meadow ecosystem, so artificial planting of Polygonum viburnum has been widely promoted. Now artificially planted Polygonum viburnum is mainly based on wild species. [0003] At ...
