Description

technical field

[0001] The invention belongs to the technical field of microbial pesticide preparation. Specifically, it relates to bacillus thuringiensis for preventing and controlling soybean cyst nematode and root-knot nematode incognita, as well as its preparation and application. Background technique

[0002] Plant pathogenic nematodes belong to the phylum Nematoda, class Secernentea, and most of them belong to the order Thyrocystis. The main path of pathogenicity is that the larvae invade the plant from the root tip of the plant, the pathogen is in the plant, plunders the plant nutrition, and causes damage to the plant such as nutrient deficiency, physical damage, chemical pathogenicity and compound infection (Sharon et al., 2001). The general symptoms are short stature, wilting, deformity, abnormal color, early wilting, etc. In severe cases, the whole plant will wither and die.

[0003] The serious harm brought by plant pathogenic nematodes to the development of ag...
