Detection of Ditylenchus destructor in potato during the growing season and in storage

Abstract

The research on detection of Ditylenchus destructor in growing plants of potato and in stored tubers was carried out. It showed that during vegetative growth visual symptoms of disease are almost imperceptible and can be observed only at a high-level infestation (100%) of seed material. Even the cutting of seed potatoes cannot always reveal the symptoms of a disease which is latent. Cutting of tubers 30 days before planting appeared to be an improving method. The best preventive measure included sprouting of tubers for 30 days, with sorting them out before and after sprouting.
