Besides, weak export demand dampened trading sentiments.
At the National Commodity and Derivatives Exchange, guargum for delivery this month dropped by Rs 120, or 2.19 per cent, to Rs 5,350 per quintal, with an open interest of 832 lots.
Also, most-active April delivery slipped by Rs 60, or 1.09 per cent, to Rs 5,460 per quintal, with a business turnover of 26,101 lots.
Marketmen said apart from profit-booking at prevailing levels, weak export demand too attributed the fall in guargum prices.
