Microbial pesticide inhibiting the outbreak of plant disease damage

Abstract

It is intended to provide a microbial pesticide for controlling plant disease damage by applying a microbial pesticide which contains a fungus Verticillium lecanii capable of inhibiting the growth of plant pathogenic microorganisms to plants such as fruits and vegetables; and a soil conditioner for exerting a soil conditioning effect by applying a microbial pesticide for controlling soil disease damage which contains the fungus Verticillium lecanii to soil. By applying, as a microbial pesticide, the fungus Verticillium lecanii, preferably a strain capable of fixing to plant surface and / or a strain capable of fixing to plant root surface and / or capable of fixing to rooting zone to plants, the growth of not only pest insects but also plant pathogenic microorganisms can be remarkably inhibited. By applying it to soil, moreover, the growth of pathogenic microorganisms occurring in plant roots and the rooting zone thereof can be inhibited. Thus, the soil can be conditioned without a risk of the occurrence of pathogenic microorganisms even in the soil after transplanting.

Description

technical field [0001] The present invention relates to the microbial pesticide that suppresses the occurrence of plant disease, specifically to the microbial pesticide containing insect parasitic filamentous fungus Verticillium lecanii, and by spreading the microbial pesticide on plants such as fruits and vegetables or applying it to plant cultivation Soil microbial pesticides that inhibit the growth of plant pathogenic bacteria and improve the soil. Background technique [0002] Due to the advances in the research on the pest control of vegetables, fruits, rice, wheat, fruit trees and other plants or the use of chemical substances for the control of soil pests attached to plant roots, at present, relying on chemical insecticides and fungicides is the mainstream. However, on the other side of the excellent effect of pesticides using chemical substances, there may be some that are toxic to humans and animals, remain in the natural environment and affect other ecosystems, and...

Problems solved by technology

However, on the other side of the excellent effect of pesticides using chemical substances, there may be some that are toxic to humans and animals, remain in the natural environment and affect other ecosystems, and what is more, due to long-term use, resistant pests and diseases, Even killing the natural enemies that exist in nature will cause problems such as the environment where harmful organisms occur
