Example Embodiment
[0021] Example 1
[0022] A biological pesticide. The weight ratio of each component based on the total weight of the raw materials is: 65% corn stalk, 25% corn cob, 2.5% wormwood, 5% pumpkin stems and leaves, and 2.5% danica.
[0023] The preparation method is as follows: take various raw materials in proportion, pulverize and stir and mix, and then steam sterilize (Systec HX-540 cabinet autoclave) after mixing, then add Bacillus amyloliquefaciens seed liquid to the raw materials and mix them Carry out solid-state fermentation, the fermentation temperature is 25-30°C, and the fermentation time is 7-15 days. After taking it out, it is dried and crushed through a 20-mesh sieve to obtain the product.
