Compound microorganism wettable powder for preventing and controlling nematodes as well as preparation method and application of compound microorganism wettable powder

Abstract

The invention discloses compound microorganism wettable powder for preventing and controlling nematodes and a preparation method and application thereof.The powder is composed of effective components and auxiliaries, and the effective components comprise paecilomyces lilacinus powder obtained by fermenting paecilomyces lilacinus WZ004 with the preservation number of CGMCC No.13761 and penicillium oxalicum powder obtained by fermenting penicillium oxalicum WZ006 with the preservation number of CGMCC No.13763; the auxiliary agent is kaolin, a dispersing agent NNO and sodium lignin sulfonate. The invention has the following beneficial effects: (1) the two microbial agents complement each other and can effectively prevent and control nematodes; (2) the affinity is good, and the survivability and stability of spores are ensured; (3) soil-borne diseases can be prevented and treated; and (4) plant growth can be promoted.

Description

Problems solved by technology

[0003] In recent years, due to the continuous expansion of continuous cropping area and unscientific use of drugs, nematodes have developed and spread faster, their resistance has increased, and the rate of dead seedlings of crops has continued to increase. affected crop production

[0004] There are a variety of nematode control bacterial agents on the market, but due to the single species of bacteria and the incompatibility of additives, it has caused difficulties in transportation and storage, and has disadvantages such as short shelf life.
