preparation example Construction

[0038] The present invention has no special limitation on the preparation method of the agricultural insecticidal composition, and the technical scheme for the preparation of the composition well-known to those skilled in the art can be adopted; specifically, the present invention combines the above-mentioned technical scheme with pharmaceutically active components, pharmaceutical carriers and auxiliary Prepared by mixing the ingredients.

[0039] The agricultural insecticidal composition described in the present invention can be applied to the aspect of crop pest control, and an application of the agricultural pesticidal composition described in the above technical scheme in the control of crop pest pest is provided. The specific applicable crop types include vegetables, Cereal crops, fruit trees, rice, tea trees, sugarcane, etc., the agricultural insecticidal composition described in the present invention can control various pests and harmful mites, including cabbage caterpilla...

Embodiment 1

[0043] Preparation of solid powdered Beauveria bassiana: Inoculate the preserved Beauveria bassiana strains into eggplant-shaped bottles with nutrient agar medium, and culture them at 28°C for 10 hours for activation culture; the activated Beauveria bassiana strains are inoculated at 121°C In the liquid medium after sterilization for 35 minutes, carry out liquid fermentation in a fermenter, specific fermentation conditions: temperature 27°C; pH value 6.9; tank pressure 0.08MPa, fermentation ventilation 1V / V min; The fermentation time is preferably 32 hours; after 30 hours of fermentation, the total number of fermented viable bacteria is detected, and when the total number of viable bacteria reaches 9.5 billion / ml, the fermentation is stopped to obtain a Beauveria bassiana fermentation liquid; the obtained Beauveria bassiana fermentation liquid is inoculated on a solid medium Among them, the specifically described solid medium includes the following components by weight: 55 part...

Embodiment 2

[0045] An agricultural insecticidal composition comprises the following components: 55.2 parts of solid Beauveria bassiana powder prepared in Example 1, 16.7 parts of 15% abamectin concentrate, 25 parts of light calcium carbonate, agricultural milk 700 (auxiliary agent) 3.1 parts were mixed to obtain an agricultural insecticidal composition.

[0046] Example 2

[0047] A kind of agricultural insecticidal composition comprises the following components: solid Beauveria bassiana powder prepared in embodiment 1, 25 parts, 10% abamectin concentrate, 1 part, light calcium carbonate (carrier), 30 parts , white carbon black (carrier), 36 parts, agricultural milk 700 (auxiliary), 8 parts.

Abstract

The invention relates to an agricultural insect-killing composition with abamectin and beauveria bassiana as main active ingredients and application thereof.The agricultural insect-killing composite contains active drug components, pesticide carriers and auxiliaries.The drug components include abamectin and beauveria bassiana, and the weight ratio of abamectin to beauveria bassiana is (0.06-6):100.The agricultural insect-killing composition has no harmful effect on humans or livestock or natural enemies, abamectin and beauveria bassiana are compounded and have high complementarity, resistance of pests to beauveria bassiana is reduced, the concurrent treatment effect of abamectin is improved, the residual life of abamectin is prolonged, resistance cannot be easily generated, and the economic benefit is quite remarkable.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an agricultural insecticidal composition and its application. Background technique [0002] Agriculture is the foundation of the national economy, the source of human food and clothing, and the foundation of survival. The development of agriculture directly affects the overall development of the national economy. In agricultural production, pests will seriously affect the growth of crops, affect agricultural harvest, and bring serious economic losses to farmers. Therefore, effective control of crop pests is of great significance to ensure the economic interests of farmers and food security. [0003] At present, there are many kinds of pests that harm crops, mainly insects, Lepidoptera pests and Coleoptera pests, such as diamondback moth, cotton bollworm, corn borer, scarab, and underground pests such as grubs and mole crickets. Agricultural pesticides in the prior art can be classified...
