The West Bengal government has issued a blanket ban on importing seed potatoes, particularly from Tamil Nadu, Uttarakhand, Himachal Pradesh and Jammu and Kashmir owing to presence of potato Cyst Nematode (globodera rostochinensis & G. Pallaid) in the produce.
The notification from the Department of Agriculture was issued on November 2 following a warning from the Union Agriculture and Farmers department prohibiting movement of seed potatoes from the aforementioned Indian states to all other states.
According to uniindia.com, the notification directed all seed inspectors of the state to strictly adhere to the restriction of prohibiting movement of seed potato from the said four states into Bengal territory.
