Compound composition of propargite and acrylonitrile acaricide

Abstract

The invention relates to a compound composition of an acrylonitrile acaricide and propargite. The compound composition is characterized in that the compound composition is prepared by mixing the acrylonitrile acaricide and propargite used as active ingredients and then adding adjuvants commonly used in preparation of preparations, wherein a weight ratio of the acrylonitrile acaricide to propargiteis (5-30): (30-15), and the acrylonitrile acaricide is cyenopyrafen or cyflumetofen. The above two active ingredients produce obvious synergism after compounding, so the dose of the compound composition can be reduced, and generation of drug resistance in pest mites can be delayed. The compound composition is applicable to prevention and treatment of pest mites attacking crops, especially pest mites attacking fruit trees, cotton and vegetables.

Description

technical field [0001] The invention relates to an acaricidal composition, specifically an acaricidal composition with synergistic effect, which is binary compounded with propargate and another acaricide of acrylonitrile type as active components, and belongs to the field of pesticide compounding. Background technique [0002] Selenium is an essential trace element for the human body. Selenium participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. Among them, glutathione peroxidase catalyzes the conversion of hydroperoxide or lipid peroxide into water or various alcohols in vivo, eliminates the attack of free radicals on biofilms, and protects biofilms from oxidative damage; Selenium participates in the formation of iodothyronine deiodinase. At the same time, selenium has the effect of reducing and alleviating the toxicity of heavy metals, so selenium-enriched agricultural products have the effect of health care. In orde...

Problems solved by technology

At present, the control of acarid pests on fruit trees, vegetables and tea trees in my country mostly uses acaricides with a single active ingredient, and the effect is not ideal. The acaricide rate of new high-efficiency acaricides such as spirodiclofen is only 60% to 60%. Between 70%

In the long-term use of a single pesticide, it is easy to cause pests to develop resistance. Research in the field of pesticide compounding has screened out pesticide compounds that have synergistic effects with each other through a large number of experiments, and successfully developed an environmental Friendly pesticide dosage forms play a vital role in improving drug efficacy, reducing pesticide residues, and reducing pest resistance
