Abstract

Benomyl fungicide almost completely controlled ring spot in Brussels sprouts, and was better at the 1 per cent level of significance than all other fungicides included in the trial. Daconil 2787 resulted in 90 per cent control and was significantly lower in number of lesions per leaf at the 1 per cent level than were maneb and maneb plus zinc compounds which gave 72 per cent control. Some degree of control (42 to 50 per cent) was given by captan, copper and thiram.
