Problems solved by technology

For example, when matrine preparations are used in the field, matrine is prone to photolysis and hydrolysis in the natural environment, which affects the efficacy and persistence of matrine, and the control effect on pests is affected to a certain extent.
As a newly synthesized insecticidal active compound, pyraclostrobin has a good control effect on fall armyworm at present, but in order to improve the control effect of pesticides on fall armyworm, farmers continue to increase the dosage of pesticides. lead to the development of insecticide resistance

Abstract

The invention relates to a preparation for preventing and controlling spodoptera frugiperda based on biopesticide and a preparation method and application thereof, which belong to the field of plant protection and comprises the following active ingredients in percentage by weight: 0.1 to 10.0 percent of sophocarpidine, 0.1 to 10.0 percent of pyraquinil and the balance of adjuvant. The preparationmethod comprises the following steps of mixing the raw materials according to the weight ratio, and preparing a suspending agent by using a traditional suspending agent preparation method. The invention discloses application of the pesticide preparation. The suspending agent is prepared from the main agent, and the prepared preparation has the advantages of high efficiency on the spodoptera frugiperda, thorough killing, low environmental pollution and low production cost, and is suitable for green and efficient prevention and control of the spodoptera frugiperda.

Description

technical field [0001] The invention relates to a biological pesticide-based preparation for preventing and controlling Spodoptera frugiperda and its preparation method and application, belonging to the technical field of plant protection. Background technique [0002] Spodoptera frugiperda is a polyphagous pest of the Noctuidae family Spodoptera genus. It is native to tropical and subtropical regions of America. It has the characteristics of strong migratory and dispersal ability, strong reproductive ability, heavy eating damage and difficult control. Fall armyworm damages more than 300 crops, including corn, rice, wheat, barley, and sorghum. In January 2019, Fall Armyworm was confirmed to have invaded my country's Yunnan Province from Myanmar. As of July, it had occurred in 21 provinces (municipalities and autonomous regions) in China, causing damage to corn, sorghum, sugarcane and other crops. At present, fall armyworm has been identified in 17 crops (sorghum, millet, su...
