Rot is rife in potato stores

WATCH out for rots in stored potatoes, says the PMBs Adrian Cunnington.

Some producers already have major problems within a few weeks of loading stores, he warns. "High ambient temperatures seem to have been a contributory factor. We have had a lot of samples sent in affected by pink rot, rubbery rot and watery wound rot. Secondary bacterial soft rotting is also invading the diseased potatoes and spreading the rots in store."

Store managers should inspect stores immediately, Mr Cunnington advises. If rotting is found, the amount of infection should be assessed, the cause diagnosed and action taken to reduce disease spread. That may mean reducing store temperatures or, if storage life is threatened, unloading stores, he adds.n
