Grain farmers in coastal parts of Cork, Waterford and Wexford, Galway and Donegal say they are facing financial ruin as bad weather has hampered their harvest.
A wet summer has been compounded by weeks of persistent coastal fog, leaving many farmers with up to a quarter of their crops still to harvest well after the traditional harvest period has ended.
Tillage farmers say they need help, and want Agriculture Minister Michael Creed to convene a forum of stakeholders.
The longterm impact on Irish agriculture will also be serious.
Over the past four years, the amount of land in cereal production has dropped by 100,000 acres, and that is predicted to fall by a further 67,000 acres in 2017.
