SUMMARY The new fungicides iprodione, vinclozolin and prochloraz, and also a mixture containing carbendazim and maneb, were compared with the established protectant fungicides dichlofluanid and chlorothalonil for effectiveness against grey mould ( Botrytis cinerea ) in an unheated tomato crop. Iprodione and vinclozolin gave the best control of lesions on leaves and stems but dichlofluanid was the most effective in controlling ghost‐spotting of fruit. The carbendazim/maneb mixture was effective against a carbendazim‐sensitive isolate but not against an insensitive isolate of B. cinerea . When applied 1 or 2 days after inoculation, all five protectant fungicides controlled the insensitive isolate better than the sensitive isolate.
