"If the candidates enter villages for seeking votes they will be greeted with black flags," Farmers' organisation Bharti Kisaan Union (Ekta) general secretary Sukhdev Singh said here.
"If the ruling alliance failed to concede farmers' demands who had been sitting at indefinite dharna since March 3 at Moga and Muktsar then the farmers would be forced to take next course of action," he said.
The protesting farmers were demanding allotment and possession of plot to the farm labourers in the state.
