Problems solved by technology

[0003] Although glyphosate is a broad-spectrum herbicide that kills most weeds and has a relatively high activity on grass weeds, glyphosate is not effective in controlling broadleaf, while 2,4-bis The activity of chlorophenoxyacetic acid on broad-leaved weeds is relatively high, and the activity on grass weeds is relatively low, especially for the elderly grass weeds.

Abstract

The invention discloses a composition containing glyphosate and 2,4-dichlorophenoxyacetic acid, and a use thereof. The composition is characterized in that crop accepted auxiliary materials contain glyphosate and 2,4-dichlorophenoxyacetic acid. The composition has an obvious synergistic effect on gramineous weeds represented by crabgrass and an addition effect on broad leaf weeds represented by chenopodium album thus can be utilized as a non-selective herbicide. The composition has the advantages that 1, the composition is compounded from novel drugs and has the characteristics of strong efficacy and low usage amount; the composition has weed control effects concretely comprising an obvious synergistic effect on gramineous weeds and an addition effect on broad leaf weeds; and the composition realizes that when a dosage of each drug is reduced, good weed control effects are still obtained thus a weed control cost is reduced and adverse influences caused by large dose drugs on the environment are avoided; and 2, the composition has good control effects, a fast weed eliminating speed and a strong adaptability.

Description

technical field [0001] The invention relates to a composition for controlling weeds in agriculture, in particular to a pesticide composition suitable for controlling crabgrass and quinoa. Background technique [0002] The chemical name of glyphosate is N-(phosphomethyl)glycine. It is a systemic broad-spectrum herbicide. It mainly inhibits the enolacetonyl shikimelin phosphate synthase in plants, thereby inhibiting the production of shikimelin from phenylpropanoids. The transformation of amino acid, tyrosine and tryptophan interferes with the synthesis of protein and causes plant death. Glyphosate is absorbed through leaves and non-woody stems, and is transmitted to various parts of the plant. It can control more than 40 families of plants such as monocots and dicotyledons, annual and perennial herbs and shrubs. [0003] Although glyphosate is a broad-spectrum herbicide that kills most weeds and has a relatively high activity on grass weeds, glyphosate is not effective in co...
