Abstract
CATIONIC surface-active agents are widely used as bactericides, and in recent years have been applied against a number of fungi of medical importance1. Certain agents of this type have been included in investigations at this Station of chemicals of potential value for the control of fruit diseases, especially apple mildew, Podosphaera leuco-tricha (Ell. and Ev.) Salm. Among these, didecyldi-methylammonium bromide (DDAB) was outstanding both for wetting of foliage and for disease control. In all experiments, it was used as the commercial 50 per cent liquid preparation that is already widely used in the food and beverage industries, but concentrations quoted here are in terms of active ingredient for all materials.
