Problems solved by technology

[0006] (1) Existing insecticides are only aimed at pests in the planting ground, and have no significant or no control effect on diseases in the planting ground, and the existing insecticides are only effective against certain pests;
[0007] (2) When the existing insecticides are applied to cabbage to control insect pests, they have certain side effects on cabbage, poor safety, and have a certain inhibitory effect on its growth, thereby reducing crop yield
[0008] (3) After the application of existing pesticides is completed, it is easy to cause pesticide toxin residues, which will affect the quality of cabbage and affect the food safety of cabbage

Abstract

The invention provides a muscardine insecticide suitable for diseases and pests of Chinese cabbage and a preparation method of the muscardine insecticide. The muscardine insecticide comprises the following raw materials in parts by mass: 20-29 parts of Paichongding, 3-4.8 parts of muscardine, 1.5-2.5 parts of a Flos Sophorae Immaturus extract, 1.5-2.4 parts of vincaleucoblastine, 2-3.5 parts of potassium dihydrogen phosphate, 6-9.3 parts of a cosolvent, 6-9.5 parts of an emulsifying agent, 1.5-2.5 parts of a wetting agent, 1.4-2.4 parts of a dispersant, 1.6-2.6 parts of an antifreezing agent, 0.4-0.6 part of a defoamer, 0.35-0.7 part of a preservative, and 10-16 parts of water. The invention further provides an application of the insecticide in planting of Chinese cabbage in saline-alkali soil. The muscardine insecticide has the beneficial effects that the insecticide prepared by the invention has good effect of preventing and treating diseases and pests of the Chinese cabbage in the saline-alkali soil, and after the insecticide is applied for 15 days, the controlling effects on aphid, trialeurodes vaporariorum, Oeobia undalis, plutella xylostella and imported cabbageworm respectively reach 98.2-99.6%, 89.4-92.1%, 83.7-86.4%, 73.2-76.9%, and 72.4-75.1%.

Description

technical field [0001] The invention relates to a Beauveria bassiana insecticide suitable for cabbage diseases and insect pests and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Beauveria bassiana is an entomogenic fungus of the ascomycete class. The main species include Beauveria bassiana and Beauveria b. bassiana. It often produces conidia through asexual reproduction. The hyphae have transverse septa and branches. The distribution range of Beauveria bassiana is very wide. Beauveria bassiana has been found in mountains ranging from a few meters above sea level to more than 2000 meters. Beauveria (non-ribosomal polypeptide toxoid), oosporin (benzoquinone toxoid) and calcium oxalate crystals are produced, which can cause insect poisoning, disrupt metabolism and cause death. [0003] Existing chemical insecticides have a certain degree of toxicity and side effects on crops, and will cause environmental pollution s...
