Problems solved by technology

However, since piperonyl butoxide and spinosad are two chemical compounds with large differences in chemical structure, it is necessary to wrap these two chemicals in polylactic acid microspheres at the same time, and ensure that the microspheres have the required physical and chemical properties. It has become a technical problem with relatively high difficulty. Therefore, there have been no reports on the research or products of spinosyn microspheres prepared with piperonyl butoxide as a synergist in scientific research and production.

Embodiment 1

[0035] The specific steps for the preparation method of 5%efficient multi -bacterial multi -bacterial microsphere suspension agent are as follows:

[0036] 1) Preparation of Multi -bactericine increases efficiency: Mix 6g of multi -bacterin -primary medicine, 0.1g pepper -pepperte ether mix with 24.4g of polyal acid, add 100ml dichloromethane, dissolves the ice water bath, and formulate it into a medicinal oil phase phase.Mixed suspension, mixes evenly in the gelatin solution of 1L15g / L. In the high -speed disperser, it is emulsified by a 2000rpm shear speed for 1min, the reaction temperature is 30 ° C, and the 500rpm magnet is stirred until no organic solvent flavor flavor; Pumping, dried at 40 ° C, that is, more sterilization to increase efficiency microspheres;

[0037]2) Preparation of suspenders: Take 25g of dry bactericin to increase efficiency microsphere powder, 15g wetting dispersant, 12g of magnesium silica aluminum, 15g antifreeze ethylene glycol, and 0.6G organic silic...

Embodiment 2

[0041] The specific steps for the preparation method of 4%efficient multi -bacterial microfinance microsphere suspension is as follows:

[0042] 1) Preparation of Multi -bactericine increases efficiency: Mix 8g of multi -bacterin -primary drugs, 0.1g pepper -pepperte ether mix with 24.3g polymapiline, add 100ml of methane, dissolves the ice water bath, and formulates a medicinal oil phase phase.Mixed suspension, add uniformly mixed in the 2L10g / L brillon solution, emulsified at a shear speed of 3000rpm in a high -speed disperser, and the reaction temperature is 25 ° C. The reaction temperature is 25 ° C.; Pumping, dried at 40 ° C, that is, more sterilization to increase efficiency microspheres;

[0043] 2) Preparation of suspension: Take 16g of dried multi -bacterin to increase efficiency microsphere powder, 4G wetting dispersing benzide phenol polyoxide polyoxide polyethylene polyethylene, 8g of magnesium silicate aluminum, 8g antifreeze ethylene glycol, 0.4G organic silicon foam...

Embodiment 3

[0046] The specific steps for the preparation method of 3%efficient multi -bacterin multi -bacterial microsphere suspension agent are as follows:

[0047] 1) Preparation of Multi -bactericine increases efficiency: Mixing 10g of bactericin primary drugs, 0.1g pepper -pepperte ether mixed with 20.2g of polystumin, add 100ml of methane, dissolves the ice water bath, prepared into a drug -containing oil phase phase phase -containing oil phase.Mixed suspension, adding uniform mixing in 1.5L20g / L plasma solution, 0.75min at a shear speed of 4000r / min in a high -speed disperser, 35 ° C in the reaction temperature, and mixing 900rpm in light.Organic solvent flavor; drawing filtration, dried at 40 ° C, that is, more sterilization to increase efficiency microspheres;

[0048] 2) Preparation of suspenders: Take 9g of dry bactericin to increase efficiency microsphere powder, 6G wetting dispersant, 8G magnesium silica aluminum, 6G antifreeze ethylene glycol, and 0.25g organic silicon foam.Afte...

Abstract

The invention discloses a synergistic spinosyn microsphere suspension and a preparation method thereof. Spinosyn is prepared by using spinosyn and piperonyl butyl ether as core materials and polylactic acid, a biodegradable material, as wall materials. Synergistic microspheres, and then mix spinosad synergistic microspheres with wetting and dispersing agent, thickener magnesium aluminum silicate, antifreeze ethylene glycol, silicone defoamer and water to make the synergistic type Spinosyn Microsphere Suspension Concentrate. The present invention overcomes the deficiencies of the prior art, and the prepared synergistic spinosad microsphere suspension only needs a relatively low content to possess high biological activity, thus solving the problem of low active ingredient content of the microsphere suspension Many problems in production and application are brought about. The synergistic spinosad microsphere suspension of the present invention has broad control spectrum, high drug efficacy, strong stability, little environmental pollution, long effective period, low control cost, and meets the requirements of pollution-free agricultural production.

Description

Technical field [0001] The invention is the field of pesticide processing, and it involves a compilation of efficient and multi -bacterin microsphere suspension and its preparation methods. Background technique [0002] Multi -bactericine (SPINOSAD), also known as Tastecin, is a type of large -ring endone -type compound (see below) developed in the early 1990s. It is in the soil Saccharopolyspora Belongs of thorough bacterioplasics ( Sacchaaropolysporaspinosa ) Internal metabolites produced after aerobic fermentation.Multi -bactericine also has the safety of biological pesticides and the speed of chemical synthetic pesticides, and has the advantages of low toxicity, low residue, safe and natural decomposition of insects, fast decomposition, and so on.As a naturally -generated broad -spectrum pesticide, multi -bactericin has a fast touch and toxicity for harmful insects, and the best prevention and treatment effect on lthwicidal pests (multi -bactericin is the scales of the pestic...
