Abstract
A phosphate-solubilizing bacterium, Enterobacter intermedium 60-2G, was examined for plant growth-promotion and induction of systemic resistance using a model system of cucumber and scab disease, caused by Cladosporium cucumerinum. Compared with a nonbacterized control, treatment of cucumber with E. intermedium significantly reduced the severity of scab disease after challenge-inoculation with C. cucumerinum. Treatment of cucumber with E. intermedium also enhanced cucumber growth. The 60-2G strain showed a strong antimicrobial activity against several plant pathogenic fungi including Fusarium soysporum and Magnaporthe grisea. These results suggest the E. intermedium 60-2G is a promising candidate as a biological control agent displaying multiple beneficial properties to promote plant health.
