Embodiment 1

[0043] Preparation of solid powdery Beauveria bassiana: inoculate the preserved Beauveria bassiana strains in an eggplant-shaped bottle equipped with nutrient agar medium, and cultivate for 10 hours at 28° C. to activate the culture; the Beauveria bassiana after the activation culture is 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 component...

Embodiment 2

[0045] 55.2 parts of solid Beauveria bassiana powder prepared in Example 1, 16.7 parts of mineral oil, 25 parts of light calcium carbonate, and 3.1 parts of agricultural milk 700 (adjuvant) were mixed to obtain an agricultural insecticidal composition.

[0046] Example 2

[0047] 25 parts of solid Beauveria bassiana powder prepared in Example 1, 1 part of mineral oil, 30 parts of light calcium carbonate (carrier), 36 parts of white carbon black (carrier) and 8 parts of agricultural milk 700 (adjuvant) are mixed , to obtain an agricultural insecticidal composition.

Embodiment 3

[0049] An agricultural insecticidal composition comprises the following components: solid Beauveria bassiana powder prepared in Example 1, 50 parts, mineral oil, 5 parts, diatomaceous earth (carrier), 39 parts, 6 parts.

Abstract

The invention relates to a farm-oriented insecticidal composition taking mineral oil and beauveria bassiana as main active ingredients and application thereof. The farm-oriented insecticidal composition contains active pharmaceutical ingredients, a pesticide carrier and an auxiliary agent, wherein the active pharmaceutical ingredients comprise the mineral oil and the beauveria bassiana, and the weight part ratio of the mineral oil to the beauveria bassiana is (0.06-6) to 100. The farm-oriented insecticidal composition provided by the invention is prepared by compounding the mineral oil and the beauveria bassiana, has a stable insecticidal effect and can be used for preventing and treating a plurality of types of insects which have drug resistance on chemical pesticides; and compared with traditional chemical pesticides, the farm-oriented insecticidal composition has no toxin residue, is applicable to an integrated control strategy, and has high safety and good environmental protection property.

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...
