Problems solved by technology

[0004] However, the types of existing film-spreading oils have poor spreading performance on the water surface, and the performance of the formed film has a large fluctuation in the control effect of the product
The existing common film spreading oils require active ingredients to be dissolved in the dispersion medium, so it is unavoidable to use aromatic hydrocarbon solvents that are easy to pollute the environment and polar solvents that are easy to cause oil film rupture, such as DMF, DMSO, ethyl acetate, sec-butyl acetate and NMP; on the other hand, it also makes some active ingredients that are not easy to dissolve, such as indoxacarb, cannot achieve a higher concentration; in addition, some active ingredients, due to poor stability after dissolution, such as abamectin and chlorantraniliprole benzamide; in addition, biological insecticides such as Bacillus thuringiensis generally cannot be dissolved in oily media, which limits the use of film spreading oil technology

Embodiment 1

[0036] In terms of weight percentage, 20% of Bacillus thuringiensis, 7.5% of sodium isooctyl succinate, 7.5% of fatty alcohol polyoxyethylene ether, 1% of lauryl alcohol ester, 7% of stearyl alcohol, 6% of propylene glycol phenyl ether, ortho Dibutyl phthalate 3%, butyl ether acetate 0.5%, mineral spirits to make up to 100%

[0037]Preparation process: In a mixing kettle with a stirrer, first mix Bacillus thuringiensis, sodium isooctyl succinate, fatty alcohol polyoxyethylene ether, dodecyl alcohol ester, stearyl alcohol, propylene glycol phenyl ether, diphthalic acid di Butyl ester, butyl ether acetate, and solvent oil are fully stirred and mixed, then pumped into a sand mill for sand grinding, and after sand grinding to a particle size D90≤5μm, a film-developing oil suspension is obtained, and 1000IU / ml of Bacillus thuringiensis is obtained Spread film oil suspension.

[0038] According to the same preparation process as in Example 1, the following examples were prepared. ...

Embodiment 2

[0040] In terms of weight percentage, Bacillus thuringiensis 2%, emamectin 1%, sodium isooctyl succinate 7.5%, fatty alcohol polyoxyethylene ether 7.5%, lauryl alcohol ester 8%, stearyl alcohol 2 %, 1% propylene glycol phenyl ether, 3% dibutyl phthalate, 4% butyl ether acetate, 22% xylene, and solvent naphtha to make up to 100%; film oil suspension.

Embodiment 3

[0042] In terms of weight percentage, Bacillus thuringiensis 14%, dinotefuran 5%, sodium isooctyl succinate 2%, fatty alcohol polyoxyethylene ether 10%, lauryl alcohol ester 3%, stearyl alcohol 3%, propylene glycol 4% phenyl ether, 4% dibutyl phthalate, 2% butyl ether acetate, 8% ethyl acetate, and make up to 100% ethanol. A film-spreading oil suspension containing dinotefuran and Bacillus thuringiensis was obtained.

Abstract

The invention provides an agritol-containing film spreading oil suspension. The agritol-containing film spreading oil suspension comprises, by weight, effective ingredient, namely agritol with the content of 1000IU / microliter-25000IU / microliter, 1.0-25% of surfactant, 1.5-25% of film-forming agent, and the balance being oily dispersion medium. The film spreading oil suspension further comprises organic insecticide which is one or several of emamectin benzoate, dinotefuran, thiamethoxam, abamectin, thiacloprid, spinosad, flonicamid, chlorbenzuron, chlorantraniliprole, diflubenzuron and indoxacarb. The agritol-containing film spreading oil suspension has significant control effect on pests, and the control efficacy can reach 83-86%. Compared with the conventional film spreading oil suspension, the agritol-containing film spreading oil suspension has good effect and excellent spreading performance on the liquid level.

Description

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to a film-spreading oil suspension containing Bacillus thuringiensis and its application in preventing and controlling crop pests. Background technique [0002] Film-spreading oil is an oil that is applied on the water surface to form a thin film. It has the characteristics of remarkable control effect, labor-saving and low cost of control. Compared with other pesticides, the dosage and cost are lower. Moreover, in the process of use, the operation is simple, no plant protection equipment is needed, and the medicine is directly dropped into the water, which improves the work efficiency by 20 times compared with conventional spraying, greatly reduces the labor intensity of spraying, is conducive to labor conversion, and changes the existing traditional heavy spraying. method. In addition, the dosage form is not affected by the climate, and the medicine can be directly ...
