Problems solved by technology

[0005] The purpose of the present invention is to: in view of the above prior art using chemical methods to prevent and treat diseases, the problem of drug resistance caused by single agent use and waste of resources caused by special medicine, the present invention provides a method for preventing and treating diseases. A compound agent for plant diseases and insect pests such as peanuts and wheat. The compound agent can simultaneously have excellent control effects on plant diseases and insect pests such as peanut blight, peanut grub, wheat stem rot, and wheat aphids. Azole, difenoconazole, and clothianidin are prepared by compounding three single-dose agents, which have the effect of one drug with multiple uses, and have both bactericidal and insecticidal effects, and further solve the problem of existing long-term use. The technical problem that a single agent prevents and treats plant diseases to produce drug resistance, resulting in poor control effect

Abstract

The invention discloses a compound medicament for preventing and treating plant diseases and insect pests of peanuts, wheat and the like, the medicament is prepared by taking albendazole, difenoconazole and thiamethoxam as base materials according to a specific compounding proportion, and the compound medicament is prepared by the following method: 1) respectively dissolving the albendazole and the difenoconazole to prepare a single-agent mother solution; 2) mixing the two single-agent mother solutions to prepare a prothioconazole-difenoconazole mixture, and mixing the mixture with the thiamethoxam single-agent mother solution to prepare a prothioconazole-difenoconazole-thiamethoxam ternary mixture; 3) diluting the ternary mixture to prepare a 20-70% compound medicament, the compound medicament can be used for preventing and treating plant diseases and insect pests such as peanut southern blight, peanut grubs, wheat stem rot and wheat aphids at the same time, the effect that one medicament has multiple purposes is achieved, the bactericidal effect and the insecticidal effect are achieved at the same time, and the technical problem of poor prevention and treatment effect caused by drug resistance generated by long-term use of a single agent for prevention and treatment of plant diseases in the prior art is further solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant disease prevention and control, and in particular relates to a compound agent for preventing and treating plant diseases and insect pests such as peanuts and wheat. Background technique [0002] Peanut blight and peanut grub are two important pests and diseases on peanut. Peanut canker sores is a disease caused by the infection of Sclerotinia sclerotiorum and occurs on peanuts. Peanuts can be infected by canker sores at every growth stage, mainly damaging the stems, fruit stalks, pods and roots of the plants. Blight has developed into one of the important diseases on peanuts, which seriously affects the yield of peanuts. Peanut blight has become an important factor restricting the yield and quality of peanuts. Peanut grubs are caused by grubs, which are the larvae of beetles or beetles, commonly known as Grubs, etc., have a wide range of feeding habits. They like to eat freshly sown se...
