Trichoderma citrinoviride strain Snef1910 for killing root-knot nematodes and metabolite and application thereof

Abstract

The invention discloses a Trichoderma citrinoviride strain Snef1910 for killing root-knot nematodes and a metabolite and application thereof. The Trichoderma citrinoviride strain Snef1910 was preserved in China General Microbiological Culture Collection Center (CMGCC) on March 10, 2017 with a preservation number of CGMCC No.13569. The Trichoderma citrinoviride strain Snef1910 can be used for preparing biological agents for killing root-knot nematodes, can effectively control root-knot nematode damage of crops with distinct effect, can improve soil microenvironment, and can promote plant growth; and has good application prospects in controlling crop root-knot nematode damage.

Description

technical field [0001] The invention belongs to the technical field of microbial pesticides, and in particular relates to a root-knot nematode-killing Trichoderma auranthoderma Snef1910, metabolites and applications thereof. Background technique [0002] Root-knot nematode (Meloidogyne) is a highly specialized omnivorous plant pathogenic nematode. Due to continuous cropping obstacles, damage and disasters are more common in facility agricultural production, the problem of root-knot nematode damage is becoming more and more serious, causing large yield losses to crops, and even failure in severe cases. [0003] Root-knot nematode control methods mainly include chemical agent control method and microbial control method. The chemical agent control method mainly uses chemical pesticides such as abamectin and Fufuduo. Although this method is effective, it does great damage to the soil and crops. Not conducive to long-term use. Microbial control mainly utilizes the poisonous eff...
