Abstract
Purified bacterial strains that are effective for the inhibition of plant pathogens, including the fungi Rhizoctonia solani and Pythium ultimum have been isolated. These strains are useful as biocontrol agents, and can be used to produce antifungal metabolites, such as antibiotic compounds, active against the plant pathogenic fungi Rhizoctonia solani and Pythium ultimum. Both the purified bacterial strains and the antibiotic compounds can be used as active agents for biocontrol compositions.
Claims5
A biologically pure strain of Pseudomonas fluorescens selected from ATCC 55171, ATCC 55170, ATCC 55169, ATCC 55175, ATCC 55174. and ATCC 55168.
A biocontrol composition comprising at least 0. 1% of at least one Pseudomonas fluorescens strain selected from the group consisting of ATCC 55171, ATCC 55170 ATCC 55169, ATCC 5175, ATCC 55174, and ATCC 55168.
