Several newly evolved strains of the disease known as potato virus Y, or PVY, can render potatoes unmarketable and reduce crop yield. What’s worse is the new viruses are particularly difficult to detect with the naked eye.

With pesticide resistance rising in species of aphids which feed on potatoes and spread viruses, one of the best control options for growers battling these pests may be found in nature, free of charge: parasitic wasps.

Potato tubers are affected by a number of blemishes, which can cause severe economic losses. This 'Focus on Potato' presentation by Jacquie van der Waals, Professor at the University of Pretoria in South Africa can serve as a guide for growers and others in the potato industry to help with identification of these blemishes.
