Herbicide

Abstract

The invention relates to a herbicide. The herbicide comprises following raw materials in parts by weight: 40-60 parts of acetochlor, 20-50 parts of glyphosate, 1-5 parts of polyvinyl alcohol, 3-10 parts of fluroxypyr-mepthyl, 3-8 parts of acetone and 2-10 parts of a surfactant. The glyphosate is used for enabling a ternary component to have the obvious synergistic effect by a pure stem and leaf uptake and translocation effect and the combination of fluoroglycofen-ethyl and the fluroxypyr-mepthyl through different mechanisms of stem and leaf touch and root inner uptake and translocation. The glyphosate and a salt thereof are of a low-toxin sterilant herbicide and can be used for preventing and removing all green plants.

Description

technical field [0001] The present invention relates to a herbicide. Background technique [0002] Corn is a common food in our daily life, but weeds are easy to grow in the fields when planting this crop, which will affect the growth of corn, so weeds need to be removed. At present, chemical methods are commonly used for weeding, and the chemical agents used are mainly acetochlor and broad leaf powder. Due to the short efficacy period of acetochlor, it is necessary to use multiple medications during the growing season of corn, which is not only labor-intensive, but also costly. High; although Kuoye powder has a good weeding effect and a longer efficacy period, the price is higher, which will also lead to higher costs.

At present, chemical methods are commonly used for weeding, and the chemical agents used are mainly acetochlor and broad leaf powder. Due to the short efficacy period of acetochlor, it is necessary to use multiple medications during the growing season of corn, which is not only labor-intensive, but also costly. High; although the weeding effect of Kuoye powder is good and the efficacy period is long, the price is relatively high, which will also lead to an increase in cost
