Embodiment 1

[0015] Example 1: (1) Mix 10% glufosinate-ammonium technical material with required 5% alkyl glycoside (APG), 5% dioctyl sulfosuccinate sodium salt (rapid penetration agent T), 12% fatty alcohol Polyoxyethylene ether (AEO-5), 8% castor oil polyoxyethylene ether (EL-10)

[0016] Dissolve in deionized water and stir to form a uniform and transparent water phase system. Add 0.6% of ethyl carboxylate to 5% soybean oil, 5% isopropyl myristate, and 5% pine nut base vegetable oil and stir to make ethyl The technical substance of carboxyfluorfen is completely dissolved in the oily substance, forming a transparent oil phase system. Slowly add the oil phase system to the water phase system under the condition of rapid stirring, and continue stirring after the addition until a viscous uniform transparent microemulsion system is formed, that is, a microemulsion of 10.6% glufosinate-ammonium and acifluorfen combination is obtained herbicide.

Embodiment 2

[0017] Example 2: (1) Combine 12% glufosinate-ammonium technical material with required 6% alkyl glycoside (APG), 6% dioctyl sulfosuccinate sodium salt (rapid penetration agent T), 12% fatty alcohol Polyoxyethylene ether (AEO-5) and 6% sorbitan polyoxyethylene ether (TWEEN20) were dissolved in deionized water and stirred to form a uniform and transparent water phase system. Add 0.8% ethyl carboxylate to 6% Stir and heat isopropyl laurate, 6% isopropyl myristate, and 5% pine nut-based vegetable oil to completely dissolve acifluorfen in the oily substance and form a transparent oil phase system. Slowly add the oil phase system to the water phase system under the condition of rapid stirring, and continue stirring after the addition until a viscous uniform transparent microemulsion system is formed, that is, a microemulsion of 13% glufosinate-ammonium and acifluorfen combination is obtained herbicide.

Embodiment 3

[0018] Example 3: (1) Mix 15% glufosinate-ammonium technical material with required 5% alkyl glycoside (APG), 5% dioctyl sulfosuccinate sodium salt (rapid penetration agent T), 12% fatty alcohol Polyoxyethylene ether (AEO-5), 8% castor oil polyoxyethylene ether (EL-10)

[0019] Dissolve in deionized water and stir to form a uniform and transparent water phase system. Add 1.0% ethyl carboxylate to 8% soybean oil, 8% isopropyl myristate, and 12% pine nut-based vegetable oil and stir to heat the ethyl carboxylate. The technical substance of carboxyfluorfen is completely dissolved in the oily substance, forming a transparent oil phase system. Slowly add the oil phase system to the water phase system under the condition of rapid stirring, and continue stirring after the addition until a viscous uniform transparent microemulsion system is formed, that is, a microemulsion of 16% glufosinate-ammonium and acifluorfen is obtained herbicide.

Abstract

The invention provides a micro-emulsion herbicide containing glufosinate and fluoroglycofen-ethyl components and a preparation method of the micro-emulsion herbicide. The micro-emulsion herbicide is prepared from the following components in percentage by weight: 1 to 50 percent of glufosinate-containing crude drug, 0.5 to 10 percent of fluoroglycofen-ethyl crude drug, 1 to 30 percent of surfactants and 1 to 30 percent of oily substance. The invention provides a solution for solving the problems of poor pesticide effect and slow effect when the glufosinate is used in a low-temperature region. The micro-emulsion herbicide is prepared from the following components according to the percentage: 1 to 50 percent of the glufosinate-containing crude drug, 0.5 to 10 percent of the fluoroglycofen-ethyl crude drug, 1 to 30 percent of the surfactants and 1 to 30 percent of the oily substance. A formula of a preparation contains the surfactants including a wetting agent, a penetrating agent, a dispersant and the like and plant-derived modified oil; air pores of leaves of weeds are stimulated to be opened under the conditions of low temperature and drought, and absorption of the weeds on the glufosinate medicament is promoted; the disadvantages that the pesticide effect of singly utilizing the glufosinate crude drug in the low-temperature region is poor, the weeds are slowly killed and the weeding effect is poor are obviously relieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to solving the problems of poor efficacy of glufosinate-ammonium in low-temperature areas, slow weed death and poor weeding effect. Background technique [0002] Glufosinate-ammonium is currently one of the large-tonnage herbicides in the world. Compared with glyphosate, glufosinate-ammonium has a better effect on removing some perennial vicious weeds, and is more competitive in the field of high economic value crops. The only alternative to glyphosate, the herbicidal effect of glufosinate-ammonium is mainly affected by three factors, namely: humidity, temperature, and light. Influence of humidity: In dry climate, plants close stomata, curl leaves, and thicken leaf skins in order to reduce transpiration, which is not conducive to the absorption of glufosinate-ammonium and affects the efficacy of the drug; the air is humid, the wax layer on the surface of plant leaves ...
