Beauveria bassiana is a pathogenic fungus. After application, under suitable environmental conditions, it can be subdivided to produce conidia. After conidia are in contact with pests, they can adhere to the epidermis of the pests. The spores sprout into the germinating tube, and the top of the germ tube produces lipase, proteinase and chitinase to dissolve the outer shell of the insect, and invade the host to grow and reproduce. It consumes a lot of nutrients in the body of the pests, and forms a large number of hyphae and spores to fill the insect body. It can also produce toxins such as white cinnabarin, ovoosporin and oosporin, which disturb the metabolism of the pests and eventually lead to death.

Application:
Control pests such as cockroaches, garlic mites, root mites, etc., when the larvae of the larvae are applied at the peak of the larvae, that is, the tips of the leaves of the leeks begin to yellow and soften and gradually fall to the ground, using 15 billion spores per acre. / 250 g of granules of Beauveria bassiana, mixed with fine sand or sand, or mixed with ash, gluten, wheat bran, etc., can also be mixed with a variety of fertilization, organic fertilizer, seedbed fertilizer Apply, apply or apply to the soil around the roots of the crop.
Control underground pests such as cockroaches, cockroaches, and golden worms. Before planting or before planting, use 15 billion spores/gram of Beauveria bassiana granules of 250-300 grams per acre, 10 kilograms of fine soil, or with wheat bran and soybean meal. Mixing corn glutinous rice, spreading, ditching or acupoint application, then sowing or planting, can effectively control the harm of various pests in the ground.
Control pests such as Plutella xylostella, corn borer, aphids, etc., can be sprayed at low ages of pests, using 20 billion spores per gram of Beauveria bassiana to disperse oil suspension 20-50 ml, 30 kg water, choose Spraying on a cloudy or sunny afternoon can effectively prevent the hazards of the above pests.
Control pests such as pine caterpillars, tea green leafhoppers, etc., can be sprayed with 40 to 20 spores/C. albicans suspension agent 2000-2500 times.
Prevention and control of apple, pear, poplar, eucalyptus, willow and other forests, can be used to inject wormholes with 40 billion spores/C. sphaeroides suspension 1500 times solution.
In the early stage of pests, 40 million spores/C. sphaeroides suspending agent 1500-2500 times liquid are uniformly sprayed and controlled.
