Embodiment 1

[0065] Example 1 10% Metarhizin · Matrine Microemulsion

[0066] Metarhizine: the weight percent ratio of matrine is 3:7. The metarhizine is a pure substance or a mixture containing metarhizine A, B, C, D or E, and the matrine is a pure substance or a mixture containing total alkaloids of matrine, both of which are existing products.

[0067] By weight, metarhizine 3%; Nongru 500 8%; matrine 7%; 6501 4%; acetone 3.2%; glycerin 2%; ethanol 5.6%; ethyl acetate 12.6%; . The metarhizine and matrine are dissolved in ethyl acetate, ethanol and acetone according to the proportion, and after mixing, other ingredients are added to prepare the microemulsion according to the existing conventional technology.

Embodiment 2

[0068] Example 2 10% metarhizine-matrine microemulsion

[0069] By weight, metarhizine 2.5%; matrine 2.5%; Nongru 500 4%; 6501 2%; ethanol 2.8%; glycerol 1%; ethyl acetate 6.3%; acetone 1.6%; . Dissolve metarhizine and matrine in ethyl acetate, ethanol and acetone according to the ratio, and then add other ingredients to prepare microemulsion after mixing.

Embodiment 3

[0070] Example 3 20% Metarhizin · Matrine EC

[0071] By weight, metarhizine 4%; matrine 16%; sodium alkyl sulfate 30%; acetic acid 0.5%; butanoic acid 0.5%; ethyl acetate 10%; castor oil 1%; Epoxidized Soybean Oil 11%; Laurocaprazine 2%. Put each component into the preparation kettle and mix thoroughly.

Abstract

The invention discloses a compound insecticidal main agent of destruxins and matrine and a compound insecticide. The compound insecticide comprises a main agent and an auxiliary agent, wherein the weight percentage content of the main agent is 1 to 30 percent and the weight percentage content of the auxiliary agent is 70 to 99 percent. The compound insecticidal main agent is a mixture prepared from the destruxins and the matrine in a weight ratio of 1:0.25-50. The destruxins is a pure substance or a mixture containing destruxins A, B, C, D and E, and the matrine is a pure substance or a mixture containing total matrines. The compound insecticide can be processed into emulsifiable solution, wettable powder, micro-emulsions, suspension emulsions or aqueous emulsions and the like. The compound insecticide is used for controlling vegetable foliar pests, in particular for controlling cotton aphids, and the effect is very remarkable.

Description

technical field [0001] The invention belongs to the technical field of insecticides, and relates to a novel high-efficiency biological insecticide, in particular to a compound insecticide main agent of metarhizine and matrine and the insecticide. Background technique [0002] Crop disease and pest disasters are a huge threat to agricultural production, and the application of pesticides is the main measure to control pests and diseases. However, long-term single dependence on chemical pesticides has caused "3R" side effects such as drug resistance, re-emergence, and residual toxicity. The development of new bio-derived pesticides and the rational mixing of pesticides are important strategies to overcome the side effects of "3R". [0003] Metarhizolin (destruxins, dtx) fungal antibiotics, mainly produced by the entomogenic fungi - Metarhizium anisopliae, belong to cyclic decarboxypeptide compounds, mainly act on the hemolymph immune system of insects, and are effective against...
