Problems solved by technology

[0003] At present, chemical control is still one of the important measures to control plant nematodes. Chemical nematicides (such as soil fumigant and non-fumigant) have a certain control effect, but long-term use of highly toxic chemical nematicides has brought serious consequences to the environment and human health. The dangers to come are becoming apparent

Abstract

The invention discloses a biocontrol fungus-Penicillium funiculosum S01324 isolated and screened from cysts of oat cyst nematodes. The penicillium fungus S01324 strain of the present invention has a good biocontrol effect on oat cyst nematodes, can parasitize oat cyst nematode cysts, and the parasitic rate reaches 100%; it has strong inhibition on cyst hatching and second-instar larvae Effect. The penicillium fungus S01324 strain provided by the invention has good control effect and stable control effect after dilution, is friendly to the environment, easy to cultivate the strain, has simple fermentation process for large-scale production, and low production cost.

Description

technical field [0001] The invention relates to the technical field of biological control of plant diseases, in particular to the screening, fermentation and determination of nematicidal activity of Penicillium funiculosum S01324, which has parasitic and poisonous effects on plant nematodes, and its control against wheat cyst nematodes The control application of the invention belongs to the field of agricultural biotechnology. Background technique [0002] Phytopathogenic nematodes are a class of serious plant diseases that cause economic losses of nearly US$157 billion to agriculture worldwide every year. More than 200 genera and 5,000 species of plant pathogenic nematodes have been reported, among which oat cyst nematode (Heterodera avenae) is an important pathogenic nematode that harms wheat and other wheat crops, and more than 40 species in Europe, Asia, Africa, North America, South America and Oceania All countries are distributed, and the wheat yield loss that causes ...
