This article was first published at the National Crisping Potato Workshop in Toowoomba 1997. At this time, Tony was the Industry Development Officer for the Victorian Potato Crisping Research Group. Tony was highly regarded in the Australian Potato Industry and made a significant contribution to the potato industry. In learning of his recent passing, we acknowledge his contribution and pay tribute to his success as an industry leader. His message in this article produced some 17 years ago is just as relevant today, showing that he had true vision and leadership. Our thoughts and well wishes go to the Myers family who have provided permission to reprint Tony’s original article.
Fusarium dry rot of potato is a postharvest disease that causes losses in storage of both seed and commercial potatoes. In the last few seasons there have been increased reports of dry rots in store so this article is a timely reminder on this disease issue which can be actively managed.
Seed age can significantly affect the performance of a potato crop. At any one time the seed tuber has two ages; its chronological age and its physiological age. Understanding the age of seed potatoes is critical in maximising the potential performance of a potato crop. A full fact sheet on the physiological age of seed potatoes is available to download.
Potato Virus Y or more commonly called PVY is a serious disease of potatoes worldwide. The disease is caused by a virus which is transmitted by aphids and mechanical means. PVY has grown in importance in recent years due to the formation of new more aggressive strains of the virus. The disease can cause yield and quality loss in potato crops in the form of decreased yields, misshapen tubers or internal discoloration, resulting in thousands of dollars loss. PVY has a significant impact on all sectors of potato production including seed, fresh processing. However, the production and use of certified seed potatoes inspected to meet tolerances for PVY, provide the main line of defence for the management of this disease.
From 1 November 2013 there will be changes to how Potato Cyst Nematode (PCN) will be controlled. This follows recent negotiations between the states that will change land use practices and market access arrangements for host produce marketed nationally (except Western Australia).
Current interstate quarantine controls which are based on the treatment and certification of all host produce sourced from within 20 km of a known PCN detection, will be replaced by property-based controls effective 1 November, 2013.
