With potatoes from Punjab expected to reach Bengal only in December, state cold-storage owners are planning to make use of the projected supply crunch from mid-November.
They have threatened to go on a one-day strike on November 19 unless the government revises the storage rental that has remained unchanged despite the hike in diesel prices and electricity charges.
Owners of the 422 storages chose November to demonstrate because the retail market depends solely on supply from the state cold storages during this month.
