Embodiment 1

[0031] (1) take each raw material by the corresponding embodiment 1 data of table 1;

[0032] (2) Add spinosad, Bacillus thuringiensis (80000IU / mg), organobentonite, starch phosphate, lecithin, solvent in mixing kettle, shear evenly, shearer rotating speed 2500r / min;

[0033] (3) Put it in a sand mill for ultrafine pulverization, and control the average particle size to 3 μm; the grinding temperature of the sand mill is controlled at 20-30° C., the grinding medium is zirconia beads, and the particle size of the zirconia beads is 1.0 mm.

[0034] (4) Stir evenly after grinding to get the dispersible oil suspension concentrate in the example; check and pack after passing the test.

Abstract

The invention discloses a dispersible oil suspension agent containing spinosad and agritol. The dispersible oil suspension agent is prepared from the following raw materials in percentage by weight: 0.5 to 30 percent of spinosad, 1000IU / mg to 30000IU / mg of entobakterin, 5 to 25 percent of a surface active agent, 0.5 to 4 percent of organobentonite, 0.5 to 3 percent of starch phosphate, 1 to 8 percent of lecithin and the balance of solvents. The dispersible oil suspension agent is prepared through three major steps of raw material stirring mixing, ultrafine crushing and inspection qualification. The dispersible oil suspension agent has the advantages that the suspension rate is high; the expansion performance and the permeability are good; the product performance is stable; the medicine effect is high; through being used as the dispersible oil suspension agent of pesticides to be applied to flower plants and crops such as rice, wheat, fruit trees and vegetables, the effect of preventingand controlling insects of lepidoptera, coleoptera, diptera, hymenoptera, homoptera and the like is achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a dispersible oil suspension containing spinosad and bacillus thuringiensis and a preparation method thereof. Background technique [0002] Bacillus thuringiensis (Bt for short) is a crystal-producing bacillus including many varieties. It can be used as a low-toxic insecticide derived from microorganisms, mainly with stomach toxicity. The bacterium can produce two major types of toxins, namely endotoxin (paracellular crystal) and exotoxin, which make the pest stop feeding, and finally the pest dies due to starvation, while the exotoxin acts slowly and has an obvious effect during molting and metamorphosis. This period is the peak of RNA synthesis, exotoxin can inhibit DNA-dependent RNA polymerase. The drug acts slowly, and it will take effect about 2 days after the pests eat it, and the effective period is about 1 day. Therefore, it should be used 2 to...
