Potatoes – looking poorly

Ray Dunford asked 12 years ago

I planted 2nd earlies (Maris Peer) in late Feb and early Mar 2011 into approx 14 tubs (2/3 plants in each tub). Most of the plants are still in flower but there 5/6 of them looking half withered and dying? The normally dark green leaf is now a very light green with brown spots. Am I in trouble?If so, are they all infected?

If all the potatoes were grown in the same conditions, it must be comsthing affecting just the minority.

A possibility is blackleg disease, which causes stems to rot below soil level. Investigate this and remove all affected plants and tubers. It can spread to neighbouring plants in certain conditions.
