Embodiment 1

[0019] The preparation weight percent composition is 10% (metarrhizia+veratrine) wettable powder, and the weight ratio of each raw material is as follows:

[0020]

[0021] The preparation process of the above insecticidal combination wettable powder is as follows: accurately weigh the original medicine of Metarhizium anisopliae high sporopollen and veratrine, and the weighed Metarhizium anisopliae high sporopollen and veratrine original medicinal carrier diatomaceous earth and After the white carbon black is adsorbed, mix evenly, then add the weighed sodium dodecylbenzenesulfonate, calcium lignosulfonate, wetting and penetrating agent T, PEG, etc. Below 50nm, pass through 300 and 400 mesh vibrating sieves, and take 38-48nm powder as qualified product.

Embodiment 2

[0023] The preparation weight percentage composition is 15% (metarrhizia+veratrine) wettable powder, and the weight ratio of each raw material is as follows:

[0024]

[0025] The preparation process of the above insecticidal combination wettable powder is: accurately weigh the metarhizium anisopliae high sporopollen and veratrine original drug, and absorb the weighed metarhizium anisopliae high sporopollen and veratrine original drug carrier diatomaceous earth Finally, mix evenly, and then add the weighed sodium dodecylbenzenesulfonate, saponin powder, soap, NO, etc., and mix evenly, grind it with a sand mill until the particle size is below 50nm, pass through 300, 400 mesh vibration Sieve, take the powder of 38-48nm as qualified product.

Embodiment 3

[0027] The preparation weight percent composition is 20% (metarrhizia+veratrine) wettable powder, and the weight ratio of each raw material is as follows:

[0028]

[0029] The preparation process of the above insecticidal combination wettable powder is as follows: accurately weigh the original medicine of Metarhizium anisopliae high sporopollen and veratrine, and the weighed Metarhizium anisopliae high sporopollen and veratrine original medicinal carrier diatomaceous earth, After kaolin and peat are adsorbed, mix well, then add the weighed sodium dodecylbenzenesulfonate, calcium lignosulfonate, wetting and penetrating agent T, sodium oleate, PEG, etc. Machine pulverization until the particle size is below 50nm, pass through 300 and 400 mesh vibrating sieves, and take the powder particles of 38-48nm as qualified products.

Abstract

The invention relates to a biological pesticide composition, in particular to a fungus and plant extract pesticide composition. An insecticidal composition containing metarrhizium anisopliae and veratrine is characterized by mainly comprising the metarrhizium anisopliae and the veratrine, wherein the metarrhizium anisopliae and the veratrine are mixed according to the weight ratio being (1-20):(10-2). The metarrhizium anisopliae is metarrhizium anisopliae conidia, and the content is 5-40 billion spores / gram. The veratrine is a pure substance or a mixture containing veratrum total alkali. The insecticidal composition is environmentally friendly, and can expand the insecticidal spectrum of biological pesticides, be higher in insecticidal effect and longer in lasting period, and reduce the use frequency of pesticides.

Description

technical field [0001] The present invention relates to a biological source pesticide composition, in particular to a pesticide composition of fungi and plant extracts. Background technique [0002] Metarhizium anisopliae belongs to Deuteromycetes, Polymycetaceae, Polymycetaceae, Metarhizium anisopliae, and is a broad-spectrum entomopathogenic fungus. The research and application of Metarhizium anisopliae to control agricultural and forestry pests has a history of more than 100 years. Especially in the past 20 years, more than 300 kinds of pests have been studied and applied to the control of Metarhizium anisopliae around the world, of which more than 100 kinds of pests have been tested in the field. From the perspective of the control scale and the basic fields involved in the research, Metarhizium anisopliae has become a fungal insecticide second only to Beauveria bassiana. At present, it is widely used in the prevention and control of various agricultural, forestry, anim...
