Problems solved by technology

However, the presence of surfactants has negative effects: (1) changes the physical properties of the active ingredient such as the surface of the fungus, making it from hydrophobic to hydrophilic, reducing the ability to bind to the target (i.e. due to arthropod surface or plant surface has a hydrophobic waxy layer); (2) affects the effectiveness

Embodiment 1

[0014] The specific embodiment embodiment 1 metarhizium anisopliae (Metarhizium spp.)

[0015] Put 1 kilogram of spores of Metarhizium anisopliae into a mixer (supplier NARA MACHINERY CO.LTD NMG-15), and spray 10% ethoxyethyl p-methoxycinnamate while dispersing at a high speed 0.05 liters of corn oil forms a 3-3.5 micron thick oil film on the surface of the spores; then add 99 kilograms of diatomaceous earth (fineness 300 mesh, density 2.0g / cm 3 , Bulk density 0.1-0.2g / cm 3 ), then change to low-speed stirring and spray 9.55 liters of corn oil into it. After mixing evenly, the above-mentioned materials are made into particles with a diameter of 0.3-0.5 mm by a granulator. The finished product can be artificially sprinkled to control paddy field pests alone or mixed with the carrier of the present invention, sprinkled on the ground or buried in soil to control underground pests or pests with soil life stages. Embodiment 2 Beauveria spp. preparation

Embodiment 2

[0016] Put 20 kilograms of fineness into the dry mycelium of Beauveria brongniatii (Beauveria brongniatii) of 20 meshes in the fluidized bed coating machine (supplier is Aeromatic-Fielder AG STREA-1 with coater attachment), adjust the fluidization After the gas velocity of the bed makes the materials suspend and mix, spray 1 liter of paraffin oil with the bottom spray method to form a film on the surface of the dry mycelium powder. The coated product can be alone or mixed with the carrier of the present invention, artificially sprinkled to control paddy field pests, sprinkled on the ground or buried in soil to control underground pests or pests with soil life stages. Example 3 Beauveria spp. preparation—insecticidal and fertilizing compound

Embodiment 3

[0017] Put 10 kg of coated slow-release urea with a particle size of 6-8 mm in the rolling coating machine (supplier: Shanghai Tianxiang Jiantai Pharmaceutical Machinery Co., Ltd. BY400 coating machine), and add 60 grams of Beauveria bassiana (Beauveria bassiana) spore powder, spray 20 milliliters of soybean oil while rolling, roll until all the spore powder wraps the fertilizer surface, due to the lipophilicity of Beauveria bassiana spores, vegetable oil-soybean oil forms a coating on the spore surface. Then add 140 grams of gypsum powder of 400 mesh fineness, spray into 64 milliliters of water while rolling, because plaster of paris meets water and is reduced to raw gypsum and solidifies, shows to form coating in slow-release fertilizer. When the prepared granules are sprinkled into the field, they will gradually disintegrate, releasing the Beauveria bassiana spores and fertilizer nutrients wrapped in the oil film, so as to achieve the purpose of both killing insects and fert...

Abstract

A biologic insecticide contains insecticiding microbe chosen from fungus, bacteria, actinomycetes, virus, nematode, and microsporidiosis, the microfluid film for wrapping said microbe, and carrier.

Description

technical field [0001] The invention relates to a biopesticide and a preparation method thereof. Background technique [0002] In order to ensure the shelf life of biopesticides, the active ingredients generally use dormant propagules, such as conidia and blastospores, or artificially induced dormant vegetative bodies, such as dried mycelia. The survival of the active ingredient in the field and its interaction with the target substrate (ie, the target) are restricted by environmental factors such as moisture, temperature, ultraviolet rays, and the properties of the interface between the two. [0003] The surface of arthropods or plants has a waxy layer to prevent water loss. During the long process of co-evolution in nature, the natural enemy microorganisms of these arthropods or plants have also evolved spores covered with hydrophobic substances as infectants, which enhance the resistance to target affinity. However, the current biopesticides that use living microorganis...
