P.E.I. potato growers are getting more worried about the fall harvest as heavy rains continue to fall.

'It's discouraging to get the crop to this point and then experience delays and an increased risk.'— Greg Donald, P.E.I. Potato Board

Conditions are bad across the Island, but at their worst in the west. In North Cape, 136 millimetres of rain has already fallen this month. More rain is predicted for Saturday.

"It has made for very wet fields and it is going to delay harvest operations, also it's going to increase the risk of drown-outs and also rot in areas that got excessive moisture," Greg Donald, general manager of the P.E.I. Potato Board, told CBC News Friday.

"The growers have a lot of money invested in this crop. It will be the most expensive crop as far as input costs. So it's discouraging to get the crop to this point and then experience delays and an increased risk at harvest time."

Donald said the wet conditions are being experienced by potato farmers across the Maritimes, but he noted it's still early in the harvest season and conditions could improve.
