Abstract

The invention belongs to the technical field of pest prevention and control, particularly relates to a composite microbial agent for preventing and controlling Meloidogyne arenria, and further discloses a preparation method of the composite microbial agent. The composite microbial agent for preventing and controlling Meloidogyne arenria, adopting selected composite microbes and plant extract as effective components, facilitates the synergistic effects of Lactobacillus rhamnosus, Propionibacterium freudenreichii and Bacillus amyloliquefaciens and the effects of the enzymatic hydrolysate of water chestnuts and burdocks, all the components coordinate with each other to exert the insecticidal effect, and indoor test and field test of the composite microbial agent prove that the composite microbial agent of the invention has a good killing effect on the Meloidogyne arenria, and does not affect the growth of peanuts at all.

Description

technical field

[0001] The invention belongs to the technical field of pest control, and in particular relates to a compound microbial bacterial agent for preventing and controlling peanut root-knot nematode, and further discloses a preparation method thereof. Background technique

[0002] Peanut root-knot nematode disease, also known as peanut nematode disease, is commonly known as ground yellow disease, ground drop disease, dwarf yellow disease, yellow seedling disease, etc. The second-instar larvae of root-knot nematodes will invade the young root tips of peanuts and form irregular root knots. The nematodes will drill into the middle column of peanut roots, causing root fluid seepage and nutrient loss, which will easily cause secondary diseases. Root-knot nematodes colonize and feed and stimulate root cell proliferation, and continuously damage the root tips of new roots, causing secondary roots to form clusters (root clusters), making it difficult for them to absorb nutr...
