Problems solved by technology

Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often use increased dosage to maintain the effect, which increases the cost of use and causes damage to the environment.

Abstract

The invention discloses a benazolin preparation, and relates to the field of pesticide production. The benazolin preparation is prepared from the following components by mass percent: 2-20% of clethodim, 5-35% of benazolin, 2-10% of calcium dodecyl benzene sulfonate, 2-12% of phenethyl phenol polyoxyethylene ether, 15-50% of dimethyl benzene and 55-65% of water. The invention also discloses a preparation method of the benazolin preparation. According to the preparation method, the clethodim, the benazolin and additives are mixed according to a certain proportion so as to form a compound pesticide; the compound pesticide is formed by scientifically compounding selective post-emergence herbicides with binary uptake and translocation action, and has good prevention and elimination effects for broad-leaved weeds in rape fields; when being applied in a recommended dose, the benazolin preparation is safe to crops; after the benazolin preparation is used, the drug resistance of the crops is delayed, the control effect of the pesticide is improved, the advantages of all drugs in the benazolin preparation are fully exerted, the cost is lowered, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to a grass-killing medicine and a preparation method of the grass-killing medicine. Background technique [0002] Caobuling is a selective post-emergent stem and leaf treatment agent, which is suitable for controlling broad-leaved weeds in rapeseed, wheat, alfalfa and other crop fields. Milk vetch is a plant of the Astragalus genus of the leguminous family, which belongs to the same leguminous plant as alfalfa. Cao Bi Ling should be used to control broad-leaved weeds in milk vetch fields. [0003] According to the principle of one drug, multiple treatments, the pesticides formulated by the compound preparation method according to a certain mixing ratio are called compound pesticides. Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pest...
