Embodiment 1

[0016] Heat and mix 35g butyl acetate, 30g ethanol, 14g xylene, 7g pectin, 4g rotenone, 4g azadirachtin, 6g eugenol and 16g emulsifier (heating temperature is 45°C) to obtain solution M; The above solution M was mixed with 100 g of water and then ultrasonically dispersed (frequency 15KHz) to obtain biopesticide A1.

Embodiment 2

[0018] Heat and mix 40g butyl acetate, 35g ethanol, 20g xylene, 12g pectin, 6g rotenone, 8g azadirachtin, 10g eugenol and 19g emulsifier (heating temperature is 55°C) to obtain solution M; The above solution M was mixed with 100g of water and then ultrasonically dispersed (frequency 20KHz) to obtain biopesticide A2.

Embodiment 3

[0020] Heat and mix 37g butyl acetate, 32g ethanol, 16g xylene, 10g pectin, 5g rotenone, 6g azadirachtin, 8g eugenol and 17g emulsifier (heating temperature is 50°C) to obtain solution M; The above solution M was mixed with 100g of water and then ultrasonically dispersed (frequency 18KHz) to obtain biopesticide A3.

Abstract

The invention discloses a biopesticide and preparation method thereof. The preparation method comprises the following steps: heating and mixing butyl acetate, ethanol, xylene, celangulin, rotenone, nimbin, eugenol and an emulsifier so as to obtain a solution M; and mixing the solution M and water and carrying out ultrasonic dispersion so as to obtain the biopesticide. The biopesticide provided by the invention overcomes the problems of proneness to occurrence of precipitates after long-time storage and poor bactericidal effect of common biopesticides.

Description

technical field [0001] The present invention relates to the preparation of pesticides, in particular to biological pesticides and their preparation methods. Background technique [0002] With the widespread use of chemical pesticides, their negative effects have gradually emerged. Due to the characteristics of high efficiency, low toxicity, low residue, and environmental friendliness, the development cost of biological pesticides is only 1 / 40 of that of chemical pesticides, so they can develop rapidly. Ordinary biopesticides are prone to sediment when stored for a long time, and the insecticidal effect is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a biopesticide and its preparation method, which solves the problems that common biopesticides are prone to deposits and have poor insecticidal effect when stored for a long time. [0004] To achieve the above object, the present invention provides the foll...
