Abstract
SUMMARY: Samples of potato tubers, cv. Désirée showing abnormal skin spot lesions were subjected to different temperature and chlorpropham (CIPC) treatments. The depth of penetration, of lesions was greater at low temperature (5°C) and significantly greater in the presence of chlorpropharn at 5°C. At 10–15°C there was no further skin spot penetration in the presence or absence of chlorpropham.
