Isolation of bacteria antagonistic to postharvest fungal diseases of cold-stored Brassica spp.

Bacterial antagonists of Botrytis cinerea comprising fluorescent pseudomonads (61%), Bacillus spp. (30%) and Serratia spp. (9%) were isolated from different Brassica spp. When Serratia and Pseudomonas strains which showed in vitro antagonism against B. cinerea and Alternaria brassicicola were tested for in vivo antagonism at 4 deg C using a leaf disc bioassay, P. fluorescens isolates CL42, 66 and 82, S. plymuthica isolate CL43 and S. liquefaciens isolate CL80 provided the best control of both fungi. The isolates CL42, CL82 and CL43, persisted on cold-stored cabbage leaves in large numbers, and it is suggested that they could be used for the control of B. cinerea and A. brassicicola on cold-stored Brassica spp. This paper was presented at the Anglo-Israeli Symposium on Non-chemical approaches to crop protection in horticulture held at Horticulture Research International, Wellesbourne, Warwick, UK on 23-27 March 1992.
