Antagonistic bacteria were evaluated for their effectiveness in postharvest control of grey mould on fresh-market tomatoes. Grey mould was reduced in fresh-market tomatoes treated with antagonists and artificially inoculated with Botrytis cinerea, and stored at 20 degrees C for at least 7 days. One strain, 5PVB (Bacillus amyloliquefaciens) was particularly effective. This strain apparently did not produce extracellular antibiotic substances, yet was highly active against the pathogen on both mature-green and red tomatoes. Treatment with 5PVB before storage at 10 degrees C showed only fungistatic activity against grey mould. Chilling-injured mature-green tomatoes were more susceptible to B. cinerea. On chilled fruits the bacterial antagonist completely controlled the pathogen if the treatment was applied immediately after storage at 2 degrees C. In fermentation tests on four industrial waste materials, B. amyloliquefaciens grew well and maintained its antagonistic activity when grown in two of them. In pilot experiments with wounded fruits dipped in the bacterial cell and pathogen suspension, the development of decay was effectively inhibited.
