The issue was raised in the Lok Sabha during Zero Hour by Anto Antony (Cong) who demanded that the Centre should either ban the import of rubber or hike import duties to protect the local farmers.
His mention found support from many other MPs, especially from Kerala which is the largest producer of rubber in the country.
Making an intervention, Kharge said the government had not convened a meeting of Kerala MPs yet despite giving an assurance in the previous session of Parliament.
Kharge said his party could move a privilege motion if the government did not respond soon.
Speaker Sumitra Mahajan assured the members that she would speak to the minister about this.
The consistently falling rubber prices, the members said, had caused a drastic fall in the trade of the commodity as traders shied from dealing in it for the fear of losses. They also blamed rubber imports for such a situation.
