Besides, increased arrivals of guarseed from growing regions in physical markets also weighed on sentiment.
Marketmen attributed fall in guargum prices to emergence of profit-booking by speculators at current levels and slackness in export demand at the domestic spot markets.
At the National Commodity and Derivatives Exchange, guargum for delivery in July contracts declined by Rs 110 or 1.90 per cent to Rs 5,690 per quintal, with an open interest of 40,722 lots.
