The diseases and pests of the rubber tree . enter. As previously stated, the fungus develops freely on smallpieces of Jak wood, and it has been found to spread to Heveafrom decaying Jak stumps. In this respect it resemblesFomes lignosus, and provides an additional reason for theremoval of Jak stumps.
