Novel Pseudomonas fluorescens strain PP-73 and its use as pollution-free pesticides

摘要

The present invention provides a novel Pseudomonas fluorescens bacterial strain for protecting against pathogens such as F. culmorum affecting the growth and development of plants grown in cold regions such as potatoes and wheat.;This strain was isolated and cultured in the cold zone soil and deposited in the Korea Microorganism Conservation Center (KCCM), and at the constant cell concentration of the bacterial strain or its extract protein inhibits the growth of pathogens to achieve effective protection of the plant.;The new strain was named Pseudomonas fluorescens Pp- ₇₃ and the novel use as a pesticide-free pesticide was provided through experiments and examples of treatment of these cells alone, extracts alone, mixtures of pathogens with them, and treatment of pathogens alone. .
