Phytophthora is treated with copper-based sprays or maneb or zineb.
Alternaria is minimised by keeping plants healthy with proper nutrition and water; maneb or zineb are used for control.
One of the most troublesome diseases affecting this species is anthracnose caused by Colletotrichum gloeosporioides, sometimes in association with other fungi, notably Botryodiplodia and Fusarium spp.; crop losses can sometimes amount to 70-80 per cent, but spraying at 10 day intervals with zineb or ferbam is stated to be effective.
Control involves sanitation by removal of crop debris, and fungicide treatment: maneb, benomyl, benomyl+ propineb, zineb and mancozeb have all been reported to give reasonably good results.
