RRIMFLOW: a novel method of latex extraction from hevea trees

A novel method of latex extraction called RRIMFLOW has been developed based on extensive fundamental studies carried out at the institute on biochemical and physiological aspects of latex flow. This method involves single punctures once a week (IP d/6) coupled with stimulant application weekly into applicators fixed over a scraped area of bark at the desired position on the tapping panel. Single punctures (2 mm diameter) are made outside the stimulated area with a 2 mm blunt needle mounted on a wooden handle. Latex is collected with the aid of 60 mm length and 2 mm diameter plastic straws fitted at one end into the punctures and the other end leading into a closed receptacle containing 20-30 millilitres of 10 per cent ammonia solution. The crop is collected at latex 72 hours after tapping. This novel method has been found to be effective on both virgin and renewed panels and on a wide variety of clones with yields obtained being superior to that obtained from conventional systems. The factors influencing yield responses to this system are enumerated. The several advantages of this novel method are highlighted. Some adverse effects noted are indicated. The technique can presently be used on a limited scale but its large scale adoption on young mature and premium rubber will only be possible after extensive evaluation over a longer period.

Abstract

A novel method of latex extraction called RRIMFLOW has been developed based on extensive fundamental studies carried out at the institute on biochemical and physiological aspects of latex flow. This method involves single punctures once a week (IP d/6) coupled with stimulant application weekly into applicators fixed over a scraped area of bark at the desired position on the tapping panel. Single punctures (2 mm diameter) are made outside the stimulated area with a 2 mm blunt needle mounted on a wooden handle. Latex is collected with the aid of 60 mm length and 2 mm diameter plastic straws fitted at one end into the punctures and the other end leading into a closed receptacle containing 20-30 millilitres of 10 per cent ammonia solution. The crop is collected at latex 72 hours after tapping. This novel method has been found to be effective on both virgin and renewed panels and on a wide variety of clones with yields obtained being superior to that obtained from conventional systems. The factors influencing yield responses to this system are enumerated. The several advantages of this novel method are highlighted. Some adverse effects noted are indicated. The technique can presently be used on a limited scale but its large scale adoption on young mature and premium rubber will only be possible after extensive evaluation over a longer period.
