Embodiment 1

[0059] A water-based hygienic insecticidal emulsion intermixed with pyrethrins and biological fungi is composed of the following raw and auxiliary materials in parts by mass:

[0060] Methothrin 0.5%;

[0061] "Guiyang Pythium" mosquito virus Pythium fungus 50 grams, each gram contains 1,000 bacteria and active ingredients;

[0062] Surfactant emulsifier is fatty alcohol polyoxyethylene ether 3%;

[0063] Cornstarch milk nutrient solution 20%;

[0064] Deionized water added to 100%;

[0065] Wherein, the mass ratio of the total active ingredients is 0.5% of methoproxil and 50 grams of Guiyang Pythium fungus;

[0066] In this embodiment, the preparation method of the corresponding pyrethrin and biological fungus water-based sanitation insecticidal emulsion comprises the following steps:

[0067] 1) First, put 0.5% methoproxil in equal parts into the preparation kettle, add a surfactant emulsifier for mixing and emulsification, then put them into a high-shear homogeneous emu...

Embodiment 2

[0072] The water-based emulsion of the mosquito virus Pythium fungus intermixing composition of pyrethrin and "Pythium Guiyang" is listed below, which can be made with purified water to form an oil-in-water emulsion. The formulation of this low-VOC and MTR insecticide emulsion As shown in Table 1:

[0073] Table 1

[0074]

[0075] During the preparation, the original drug of methothrin was put into the brewing kettle according to 95% equal parts, and the surfactant was added for mixed emulsification, and then put into the high-shear homogeneous emulsifier together, and stirred for 30 minutes for re-emulsification;

[0076] 1) In another preparation kettle, warm the corn starch emulsion to 30°C with deionized water, put 50g of "Pythium Guiyang" mosquito virus Pythium fungus, and after cultivating for 1 hour, inject the methyl ether emulsion In the permethrin high-shear homogeneous emulsifier, stop after 30 minutes of high-speed stirring and dispersion;

[0077] 2) Obtain ...

Embodiment 3

[0079] Listed below is the mosquito virus Pythium fungus insecticide composition aqueous emulsion by Meethofrin and "Pythium Guiyang", which can be made into demulsified water-in-oil insecticide emulsion, this low VOC and MIR insecticide The formula of concentrate is as shown in table 2:

[0080] Table 2

[0081]

[0082] The insecticide combination emulsion in this embodiment is also a low-VOC and MRI preparation, and also uses methyl soybean fatty acid as a solvent. However, low-lipophilic nonionic surfactants with a water-oil degree (HLB) in the range of 4 to 9 are used, such as sorbitan fatty esters, unsaturated fatty acid alkanolamides, vegetable oil ethyl oxides, and polyglycerol fats. esters. The use of these nonionic surfactants enables insecticide concentrates to be formulated as water-in-oil demulsifying formulations. The addition of plant essential oils not only enhances the activity and pleasant smell, but also has a bactericidal function.

Abstract

The invention provides a water-based sanitary insecticidal emulsion with mutual matching of pyrethrin and biological fungi and a preparation method of the water-based sanitary insecticidal emulsion with mutual matching of the pyrethrin and the biological fungi. The water-based sanitary insecticidal emulsion with mutual matching of the pyrethrin and the biological fungi takes the pyrethrin or pyrethroid and mosquito virus pythium fungi as active components and is further prepared from a synergist and an additive; the additive includes a food-grade or natural antioxidant and / or an emulsifier orincludes a solvent and a nutrient solution; through binary combination and mutual matching of a raw insecticidal drug and the biological fungi, the mosquito killing effect is effectively improved, andmosquitoes are enabled to be difficult to generate drug resistance; by utilizing the pyrethrin, the water-based sanitary insecticidal emulsion has the characteristics of rapidness in killing, harmlessness to people and livestock and environmental protection to pests, rapidly kills the mosquitoes and larva thereof and has the temporary solution effect; and through a bacterial virus mutual matchingtechnology of Pythium guiyangense Su or pythiumcarolinianum and the biological fungi, the biological fungi finishes the whole development to cause death of polypide after being released in water so as to reach the purpose of effecting a permanent cure, and the environment-friendly biological water-based sanitary insecticidal emulsion with double efficacies of taking temporary solution and effecting the permanent cure.

Description

【Technical field】 [0001] The invention relates to an insecticide and a preparation method thereof, in particular to a water-based hygienic insecticidal emulsion intermixed with pyrethrins and biological fungi and a preparation method thereof. 【Background technique】 [0002] For many years, preparations of natural pyrethrums and synthetic pyrethroids in volatile ethanol and petroleum-based solvents have been widely used. Although these insecticides are effective in controlling pests, their use creates serious air pollution problems due to their inclusion of volatile organic compounds (VOCs) or solvents. [0003] Biological fungus kills mosquitoes by cultivating mosquito viruses and bacteria to cause mosquito infectious diseases, resulting in infertility or disease and death, so as to achieve the effect of killing mosquitoes. Its mosquito-killing mechanism is: the fungus releases mobile diflagellated spores in the water, quickly and actively searches for mosquito larvae (male...
