Problems solved by technology

[0004] At present, the control of German cockroaches is still dominated by chemical control. However, the use of a large number of chemical insecticides not only has long-term damage to the ecological environment, but also makes German cockroaches produce a wide range of drug resistance.
However, pure biological control has the disadvantages of slow onset and long period, so it is of great significance to find safer and more effective pest control methods.

Embodiment 1-25

[0048] Metarhizium anisopliae spores are prepared into a sterile aqueous suspension and mixed with boric acid to prepare the main agent, wherein the concentration of spores in the sterile aqueous suspension of Metarhizium anisopliae spores and the concentration ratio of boric acid are shown in Table 1, and then the The main agent is mixed into the ground auxiliary agent (oleic acid and brown sugar are mixed at a mass ratio of 1:2.7 to make an auxiliary agent) and pressed into a solid block agent to obtain a compound biopesticide, wherein the content of the main agent It is 2%, and the content of adjuvant is 98%.

[0050] Example

Embodiment 26-50

[0052] Prepare compound biopesticide according to the method of embodiment 1, wherein, in main agent, metarhizium anisopliae spore and boric acid concentration ratio are as shown in table 1, and the content of main agent is 0.4%, and the content of auxiliary agent is 99.6%.

Embodiment 51-75

[0054] Prepare compound biopesticide according to the method of embodiment 1, wherein, in main agent, metarhizium anisopliae spore and boric acid concentration proportioning ratio are as shown in table 1, and auxiliary agent is by mouse complete feed and oleic acid with mass ratio 2.7:1 Mix to prepare.

Abstract

The invention provides a compound biological pesticide and a preparation method and application thereof. The compound biological pesticide takes metarhizium spores and boric acid as active ingredients, wherein the content of boric acid is less than or equal to 2%. By the arrangement, not only the additive effect but also synergistic effect in pest control can be achieved, the effective time is greatly shortened after compounding, pest killing effect is realized in less time, and boric acid is used much less than common chemical pesticides on the market.

Description

technical field [0001] The invention relates to the field of insect control, in particular to a compound biopesticide and its preparation method and application. Background technique [0002] Metarhizium anisopliae belongs to the subphylum Metarhizium anisopliae, and is a broad-spectrum entomopathogenic fungus that can parasitize a variety of insects. It has the characteristics of wide distribution range, broad parasitic spectrum, etc., and is non-toxic to humans, livestock and crops. It is one of the most researched and used entomogenic fungi in the world. According to incomplete statistics, there are more than 200 kinds of insects in the world that can be infected and killed by this fungus. Metarhizium anisopliae has significant insecticidal effect, and has a new mechanism of action different from existing insecticides, mainly acting on the hemolymph immune system of insects, causing them to lose their immune defense functions. Metarhizium anisopliae will produce various...
