Embodiment 2

[0030] Composition: 10 parts of spinosad, 5 parts of griseofulvin, 40 parts of gelatin, 60 parts of sodium alginate, 1 part of isopropanol, 0.5 parts of formaldehyde, 1 part of polyethylene glycol

[0031] The preparation method of above-mentioned spinosyn and griseofulvin composite microcapsule insecticide, it comprises the steps:

[0032] (1) Dissolving gelatin and sodium alginate in water to make a carrier solution;

[0033] (2) Mix spinosad and griseofulvin evenly, add to the above carrier solution, stir to make a suspension,

[0034] Adjust the pH of the suspension to 8;

[0035] (3) Dissolve isopropanol in water, add to the above suspension, keep warm at 20°C, and stir for 0.5 hours;

[0036] (4) Finally, add polyethylene glycol and formaldehyde and stir to obtain the product.

[0037] The spinosad and griseofulvin composite microcapsule insecticide prepared in this example is stable, has a strong effect of killing pests, and has a long-lasting effect.

Embodiment 3

[0039] Composition: 10 parts of spinosad, 15 parts of griseofulvin, 200 parts of chitosan, 1 part of tert-butanol, 1 part of ethanol, 1 part of formaldehyde, 2 parts of propylene glycol

[0040] The preparation method of above-mentioned spinosyn and griseofulvin composite microcapsule insecticide, it comprises the steps:

[0041] (1) Dissolving chitosan in water to make a carrier solution;

[0042] (2) Mix spinosad and griseofulvin evenly, add to the above carrier solution, stir to form a suspension, and adjust the pH of the suspension to 9;

[0043] (3) Dissolve tert-butanol and ethanol in water, add to the above suspension, keep warm at 30°C, and stir for 1 hour;

[0044] (4) Finally, add propylene glycol and formaldehyde and stir to obtain the product.

[0045] The spinosad and griseofulvin composite microcapsule insecticide prepared in this example is stable, has a strong effect of killing pests, and has a long-lasting effect.

Abstract

The invention discloses a pleocidin-griseofulvin composite microcapsule pesticide. The pleocidin-griseofulvin composite microcapsule pesticide is mainly prepared from 10 parts of pleocidin, 5-15 parts of griseofulvin, 100-200 parts of a carrier material, 1-2 parts of a flocculant, 0.5-1 part of a cross-linking agent, and 1-2 parts of a plasticizer. Compared with the prior art, the pleocidin-griseofulvin composite microcapsule pesticide as a pleocidin-griseofulvin composite polymer micelle pesticide has the characteristics of good medicinal stability, strong medicinal effects and long action period. The pleocidin-griseofulvin composite microcapsule pesticide can effectively kill lepidopteran, dipteran and thysanopteran injurious insects and can poison specific types of injurious insects such as coleopteran, orthopteran, hymenopteran, isopteran, siphonapteran, dermapteran and psocopteran.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a spinosad and griseofulvin composite microcapsule insecticide, which is applied in the field of agriculture. Background technique [0002] Biopesticides refer to living organisms and their metabolites and genetically modified products used to prevent and control harmful organisms such as diseases, insects, and grasses, and can be made into commercial biological source preparations, including bacteria, viruses, fungi, nematodes, plants, natural enemies of insects, Agricultural antibiotics, plant growth regulators and transgenic plants resistant to diseases, insect pests and weeds, etc. Biological pesticides have been used in agricultural production for half a century, but the development has been relatively slow due to various reasons. In recent years, people pay more and more attention to the sustainable development of agricultural production and the coordination between human and envi...
