Besides, weak overseas cues also weighed on the sentiments.
At the National Commodity and Derivative Exchange, guargum for delivery in May dropped by Rs 130, or 2.43 per cent to Rs 5,220 per quintal, with an open interest of 26,519 lots.
On similar lines, delivery in far-month July also slipped by Rs 130, or 2.39 per cent to Rs 5,300 per quintal, in an open interest of 18,371 lots.
Marketmen attributed fall in guargum prices to a weak trend at the physical market due to slackened demand amid increased arrivals of guarseed from growing regions.
