A number of farms on the South Island of New Zealand have been affected by the Potato Mop-Top Virus (PMTV). The virus was detected in September this year and 18 farms are now suspected of being affected.
PMTV is transmitted by a soil-born fungus and symptoms can include: distortions to the skin, deep cracking and rust coloured arcs streaks or flecks in the tuber flesh. It can be transmitted in soil on boots, machinery and equipment so farm biosecurity is vital in protecting your farm from PMTV.
