SUMMARYThree methods of applying four fungicides were tested for controlling powdery mildew on roses. Best results were obtained by air blast application, with high-volume sprays providing better control than low-volume sprays. The former, unassisted by air blast, failed to give adequate control. Fluorescent tracers showed that performance of various modes of application depended on their ability to provide a satisfactory fungicide deposit on the lower leaf surface, which was particularly susceptible to the disease.
