Abstract

The invention relates to a weedicide for orchards and forest lands, and relates to a weedicide composition. The weedicide composition comprises hexazinone and glyphosate which serve as active ingredients. The hexazinone, the glyphosate and corresponding auxiliary ingredients which serve as raw materials are mixed fully to prepare corresponding formulations which have different forms and can be used, such as wettable powder, soluble powder, soluble granules or soluble liquid and the like. The invention has the advantages that: the weedicide composition has an obvious synergistic effect, perennial lianas, undershrub weeds and broadleaf weeds can be weeded, annual and biennial weeds also can be weeded, a weeding spectrum is enlarged, the weeding quick action is improved, and the dose and production cost of the weedicide are reduced.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a herbicide composition used in orchards and woodlands. Background technique [0002] Glyphosate and hexazinone are currently commonly used herbicides in orchards and woodlands. Glyphosate is a systemic and conductive broad-spectrum herbicide, mainly absorbed by leaves, which can control monocotyledonous and dicotyledonous, annual and There are more than 40 families of plants such as perennials, herbs and shrubs, which have a wide range of applications, but have poor control effects on some perennial, tall, and lignified weeds. Hexazinone is a systemic selective herbicide, absorbed through the roots and stems and leaves of plants, mainly inhibits photosynthesis, causes metabolic disorders, does not harm the roots of evergreen coniferous forests, and can control most non-target plants in forest land The progress of the drug effect is slow. Both of the above two herbicides have the disa...
