Method for controlling plant soil borne disease

Abstract

The invention discloses a method for controlling a plant soil borne disease. The method comprises the steps of cultivating group beneficial microbe in soil, rapidly breeding the group beneficial microbe, forming a microbe membrane on the surface of a plant root to degrade the special organic matter secreted from the root of the plant so as to avoid contact of the special organic matter and the soil borne disease, prevent recovery of the soil borne disease, enable the soil borne disease to maintain the dormant state continuously and achieve the purpose of preventing the soil borne disease; in addition, individual the soil borne disease free from dormancy can be inhibited or killed by the inhibiting substances secreted by the microbe membrane. The invention provides a method for biologically controlling the plant soil borne disease without chemical pesticides. The harvested agricultural products have low residual hazard and good quality.

Description

technical field [0001] The invention relates to crop disease control technology, in particular to a method for preventing and controlling plant soil-borne diseases. Background technique [0002] For a long time, people have used chemically synthesized pesticides to prevent and control plant soil-borne diseases, which has made the soil-borne disease bacteria resistant to drugs, and drug-resistant mutant bacteria have appeared. Chemically synthesized pesticides not only cannot kill the bacteria, but become favorable conditions for their rapid reproduction. . Because chemically synthesized pesticides are not easy to degrade, some of them still maintain the original molecular structure and original toxicity after 10 years, so there are many types of pesticides accumulated in the soil, and the content is very high, which is very beneficial to the reproduction of resistant mutant bacteria. It reproduces rapidly and is harmful to plants. [0003] Although people are constantly de...

AI Technical Summary

Problems solved by technology

[0004] 1. The development cycle of new pesticides is very long, and the pathogens produce anti-new drug factors very quickly, so it is difficult to obtain the desired drug effect;

[0005] 2. Unlike other germs, the germs of soil-borne diseases are not born on the plants, but in the soil. Pesticides can only be sprayed on the surface of the land and on the plants. It is difficult to directly contact with the germs, and the bactericidal effect is very poor.
