AI Technical Summary

Problems solved by technology

The conventional method is to prepare a water suspension to disperse and suspend the water-insoluble herbicide in water to improve the efficacy of the herbicide in actual use, or to mix two different herbicides in a certain ratio to increase the herbicide efficacy. The efficacy and expansion of the herbicidal spectrum, these only consider the dispersibility of the active ingredients, but the results of use prove that its herbicidal effect needs to be further improved

Abstract

The invention relates to the technical field of a pesticide preparation and particularly discloses an efficient herbicide. The efficient herbicide is characterized by comprising the following raw materials in parts by weight: 24-30 parts of acetochlor, 5-12 parts of broad leaf powder, 3-6 parts of polyvinyl alcohol, 1-4 parts of gelsemium elegan, 2-4 parts of tea saponin, 4-10 parts of acetone, 3-8 parts of a surfactant and 38-50 parts of water. The efficient herbicide provided by the invention has the advantages of low production cost, high pesticide effect, low dosage, obvious weeding effect, capability of delaying the happening of weed pesticide resistance and no environmental pollution.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, and specifically discloses a high-efficiency herbicide. Background technique [0002] 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. [0003] Herbicides are widely used pesticides in modern agriculture. The main economic and technical indicators for evaluating the function of herbicides are to maximize the efficacy of killing weeds at a certain dose and to minimize the damage to the protected crops. How to improve the efficacy of chemical herbicides has always been a subject of ...
