Biological control of bacterial soft rot of cabbage.

Bacterial soft rot disease, caused by Erwinia carotovora subsp. carotovora (Ecc), is one of the major postharvest diseases of cabbage throughout the world. Chemical control of this disease is ineffective and the high risk of residual content of chemicals in cabbage might be hazardous to consumers. This study was conducted to isolate and identify potential antagonists that can inhibit the pathogen and hence reduce disease severity. Two antagonistic bacteria, identified as Pseudomonas aeruginosa and Acinetobacter genospecies 15, inhibited the growth of Ecc in vitro giving inhibition zones of 2.5 cm and 1.0-1.5 cm, respectively. In vivo evaluation indicated that both antagonistic bacteria reduced disease severity up to 25% following treatment of cabbage tissues [unspecified] with 106-107 cfu/ml of the antagonists.
