Embodiment 1

[0020] A bio-pesticide compound synergist, the raw materials and mass fractions of which are as follows: 2% cottonseed oil, 1% sodium dodecylsulfonate, 2% organic silicon, and the balance is water.

[0021] According to the above ratio, mix the raw materials evenly until the prepared preparation is not separated and forms an emulsion. Add the prepared composite synergist to the 16000 IU / mg Bacillus thuringiensis insecticide whose dilution factor is 1000 times according to the ratio of 5%, and stir evenly to obtain the Bacillus thuringiensis insecticide containing the synergist. Take the 100m in the experimental base of Yuzhou Tianyuan Biotechnology Co., Ltd. 2 The vegetable garden planted with cabbage was used as the experimental site. The experimental conditions were drought and water shortage. 2 Spray Bacillus thuringiensis insecticide containing synergist as the experimental group, the remaining 50 m 2 Bacillus thuringiensis insecticide without synergist was sprayed as a ...

Embodiment 2

[0030] A bio-pesticide compound synergist, the raw materials and mass fractions of which are as follows: 6% cottonseed oil, 4% sodium dodecylsulfonate, 6% organic silicon, and the balance is water.

[0031] According to the method of Example 1, the synergist prepared is added in a ratio of 8% to the 16000IU / mg Bacillus thuringiensis insecticide with a dilution factor of 1000 times. The experimental conditions are rainy and humid, and all the other are the same as in Example 1 . The statistical results are shown in Table 3 and Table 4.

[0032] table 3:

[0033]

[0034] Table 4:

[0035]

[0036] The results in Table 3 and Table 4 show that under the conditions of rainy and humid conditions, adding synergists can improve the insecticidal rate of Bacillus thuringiensis insecticides, reduce the resistance of cabbage caterpillars to pesticides, and reduce the concentration of liquid medicine on the surface of plant leaves. The contact angle can increase the maximum stabl...

Embodiment 3

[0038] A bio-pesticide compound synergist, whose raw materials and mass fractions are as follows: 10% soybean oil, 6% sodium dodecylsulfonate, 10% organic silicon, and the balance is water.

[0039] According to the method of Example 1, the prepared synergist was added in a ratio of 8% to the 16000 IU / mg Bacillus thuringiensis insecticide with a dilution factor of 1000 times. The experimental conditions were sunny in summer, and the rest were the same as in Example 1. The statistical results are shown in Table 5 and Table 6.

[0040] table 5:

[0041]

[0042] Table 6:

[0043]

[0044] The results of Table 5 and Table 6 show that under sunny conditions in summer, the addition of synergists can increase the insecticidal rate of Bacillus thuringiensis insecticides, reduce the resistance of cabbage caterpillars to pesticides, and reduce the contact of liquid medicine on the surface of plant leaves Increase the maximum stable retention of the liquid on the leaves, thereby...

Abstract

The invention relates to the field of biopesticides and application thereof, in particular to a biopesticide composite synergist which comprises the following raw materials in percentage by mass: 2-10% of esterified vegetable oil, 1-6% of sulfonate, 2-10% of organic silicon and the balance of water. The composite synergist can significantly reduce the contact angle and surface tension of a liquidpesticide, enhance the spreading property and adhesion of the pesticide on plant leaves, improve the permeability of the liquid pesticide, and reduce the drug resistance of pests, can be combined witha biological insecticide for disinsection, can also be combined with a biological herbicide for weeding, and can be matched with various biopesticides for use and has a wide application range.

Description

technical field [0001] The invention relates to the field of biopesticide and its application, in particular to a compound synergist of biopesticide. Background technique [0002] Pesticide synergist is a very important adjuvant in pesticide processing, mainly to inhibit or weaken the target (pests, weeds, germs, etc.) on the detoxification of pesticide activity, prevent pesticide damage, etc., and delay the metabolism of pesticides in the control object , thus increasing the biological control effect. [0003] The synergist is used in combination with pesticides to increase the wettability and adhesion of pesticides to insects and plants. Due to their own protection, insects and plants have a layer of waxy protective layer on their surface, which is not easy to wet and dry with general pesticide solutions. Adhering to the above, after adding synergists, it can greatly improve the wetting and adhesion to the waxy layer, improve the penetration ability of pesticides to cells...
