Method for producing cell extract having agricultural insect pest-killing ability and method for killing agricultural pests

摘要

A method for producing a fungal extract having agricultural insect pest-killing ability by a new culture method of a fungal fungus having insect-killing ability of agricultural pests, To provide an effective insecticidal method with excellent immediate effect in a short time. Culturing a filamentous fungus in a solid medium to obtain a solid culture of the filamentous fungus; culturing the filamentous fungus in a liquid medium to obtain a liquid culture of the filamentous fungus; and a liquid culture of the filamentous fungus Separating the mycelium of the filamentous fungus, mixing the liquid culture from which the mycelium has been separated and the solid culture to obtain a mixed culture, and the filamentous form from the mixed culture A method for producing a fungal extract having the ability to kill agricultural pests, comprising a step of extracting a fungal spore solution, and an agricultural pest that causes the fungal extract obtained by the production method to act on agricultural pests or their habitats Insecticidal method.
