More than 500 farmers on Thursday blocked the Mumbai-Agra highway in Nashik in Maharashtra for some time seeking cancellation of the Union government`s decision to impose 40 per cent export duty on onions, an official said, reported the PTI.

The stir took place in Chandwad in the rural part of the district and the arterial road was blocked for almost one-and-half hours before police rushed to the site and managed to get the protesters off the stretch, he said.
