Problems solved by technology

[0004] The effect of using Metarhizium anisopliae alone is slow and the control effect is unstable. The mixed use of Metarhizium anisopliae and dimethrin (deltamethrin), phoxim, diflubenzuron III, etc. can increase the insecticidal speed [see: Journal of Fujian Forestry University 2001 , 21(4):308~311], there have also been reports on the combination of Metarhizium anisopliae and pyrethroid pesticides, but general chemical agents have an impact on the survival and germination of spores, and it is difficult to make a stable mixed preparation

Embodiment 1

[0023] Embodiment 1: Metarhizium anisopliae. Acetamiprid Granules (100 million spores of Metarhizium anisopliae / g+Acetamiprid 5g / kg)

[0024] Take by weighing Metarhizium anisopliae (R8-4 bacterial strain, Chinese Academy of Agricultural Sciences Plant Protection Research Institute develops) 5 billion spores / g high sporopollen 20g, acetamiprid 5g, paraffin oil 10g, corncob particle 965g, acetamiprid Dissolve it with a small amount of acetone and mix it evenly with the corncob particles, then mix the Metarhizium anisopliae spore powder with the corncob particles in a mixer, so that the spore powder is evenly adsorbed on the corncob particles, and finally spray paraffin oil under stirring to seal it. Reduce spore powder shedding and reduce water absorption.

Embodiment 2

[0025] Embodiment 2: Metarhizium anisopliae. Imidacloprid wettable powder (10 billion spores of Metarhizium anisopliae / g+ imidacloprid 100g / kg)

[0026] Take by weighing Metarhizium anisopliae (Chongqing Major Biotechnology Development Co., Ltd.) 20 billion spores / g high sporopollen 500g, imidacloprid 100g, calcium lignosulfonate 30g, sodium lauryl sulfate 10g, 2,6-di-tert-butyl 20g of p-cresol and 340g of kaolin, mixed with imidacloprid, calcium lignosulfonate, sodium lauryl sulfate, 2,6-di-tert-butyl p-cresol and kaolin, and pulverized with a jet mill to obtain superfine powder , and then mix with Metarhizium anisopliae spore powder evenly to get the product.

Embodiment 3

[0027] Embodiment 3: Metarhizium anisopliae. Imidacloprid wettable powder (4 billion spores of Metarhizium anisopliae / g+ imidacloprid 80g / kg)

[0028] Weigh the Metarhizium anisopliae (R8-4 strain, developed by the Institute of Plant Protection, Chinese Academy of Agricultural Sciences) 10 billion spores / g high sporopollen 400g, imidacloprid 80g, alkylnaphthalene formaldehyde condensate sulfonate 30g, fatty alcohol polyoxygen 10g of vinyl ether, 20g of tert-butyl-p-hydroxyanisole, 460g of diatomaceous earth, mix imidacloprid, alkylnaphthalene formaldehyde condensate sulfonate, fatty alcohol polyoxyethylene ether, tert-butyl-p-hydroxyanisole and diatomaceous earth Afterwards, it is pulverized with a jet mill to obtain an ultrafine powder, and then mixed evenly with the spore powder of Metarhizium anisopliae to obtain the product.

Abstract

The invention relates to a metarhiziumanisopliae compound insecticide composition and use thereof. The metarhiziumanisopliae compound insecticide composition is characterized in that: the active ingredients of the composition include metarhiziumanisopliae and a new neonicotinoid insecticide; the density of the metarhiziumanisopliae in the composition is 1 to 10 billion spores per gram; and the new neonicotinoid insecticide content of the composition is 20 mass percent; and the rest content of the composite are pesticide auxiliary ingredients. The composition has an obvious synergistic effect on grubs and is suitable for preventing and controlling plant pests, particularly grubs. The composition can be used on various crops such as lawns, peanut, sweet potatoes and vegetables or in various places and has the advantages of stable insecticide effect, high quick-acting performance, long efficacy duration, safety and environmental protection.

Description

technical field [0001] The invention relates to a pesticide composition and its application, in particular to a compound insecticidal composition containing Metarhizium anisopliae and its application for controlling crop pests. Background technique [0002] Grub is the general term for scarab beetle larvae, belonging to Coleoptera, scarab superfamily, which damage soybeans, peanuts, sugar cane, corn, and some Chinese medicinal materials, pastures, flowers, saplings, artificial lawns, etc. Among them, peanuts are the most serious damage. In recent years, with the adjustment of planting structure, the change of crop distribution and the change of climate, grubs have occurred year after year in a large area in my country, and the damage is rampant. Grubs have a long life history, and the time required to complete a generation varies from 1 to 6 years. In the life history, the larval stage lasts the longest, and because it is harmful underground, it is quite difficult to control...
