N2  - Techniques for applying pesticides to rubber trees are reviewed.  Projection of fungicide into the canopy of tall trees has required the use of thermal fogs applying aerosol particles generally smaller than 50 mew m in diameter. But applications need to be repeated to achieve adequate control. Maintenance of pathways by application of herbicides can be improved with knapsack sprayers by fitting a spray management valvie to provide a constant 1 bar pressure at the nozzle. There has also been limited use of hand-held spinning disc sprayers to apply 250 mew m droplets of herbicides
