Screening of Bacillus isolates for potential biocontrol of the wilt disease complex of pigeon pea (Cajanus cajan) under greenhouse and small-scale field conditions
Journal of Plant Pathology 89 (2), 179-183
Abstract: Twenty isolates of unidentified Bacillus species were obtained from pathogen-suppressive soils of pigeon pea (Cajanus cajan) fields for the biocontrol of a wilt disease complex caused by Heterodera cajani, Meloidogyne incognita and Fusarium udum. Five isolates (13602, 13603, 13605, 13615 and 13618) were considered to have biocontrol potential on the basis of antifungal activity, inhibitory effect on the hatching and penetration of nematodes and colonization of pigeon pea roots by these isolates. The five Bacillus isolates were evaluated for biocontrol potential under pot conditions. Isolates 13615 and 13603 were found to be the most promising and should be further studied in field experiments.
