SUMMARY1 A serious disease of the heaths Erica hyemalis, E. nivalis and E. Willmoreana has been investigated. 2 The causal organism was isolated and identified as Phytophthora Cinnamomi Rands. 3 This was shown to be capable of causing a similar disease in Antirrhinum, Calceolaria, Schizanthus and beech seedlings. It also rots apple and tomato fruits. 4 Infection was traced to (a) contaminated water tanks, (b) the “standing‐out” ground, and (c) plunging material. 5 The water tanks were cleaned by removing the debris, scrubbing with water and finally treating with formaldehyde. 6 The need for destroying the compost from discarded pots or alternatively of sterilizing it by heat before using it again is emphasized.
