The control of Botrytis fabae (chocolate spot of broad bean) effected by foliage and root applications of captan were examined. Captan applied to the dorsal surfaces only of leaves protected the ventral surfaces of the same leaves and also leaves both above and below the foliage to which it had been applied. These systemic antifungal effects showed marked persistence. When watered on to the roots, captan gave indications of a similar systemic protection of the foliage against the same pathogen. A nomogram is provided to facilitate calculation of fiducial limits from a population of different variance.
