A good mulch cover will keep the weeds away from the growing seedlings. Ring weeding and shallow hoeing around the young trees are done every three months just before fertilizing. Weeds between trees are controlled by use of herbicides. The larvae feed on the leaves and later bore into the fruits. After destroying part of the fruit, they bore into the tender shoots and buds.
Control includes destroying affected shoots and fruits and spraying with insecticide.
Two species of fruit flies, Dacus umbrosus and Dacus dorsata , attack jackfruit which becomes rotten. Control is by destroying infected fruits and bagging young fruits. A common disease of jackfruit is bacterial shoot die-back caused by Erwinia Carotovora Var. Control is to get rid of all affected branches. Immature jackfruit are pale green and become greenish yellow and then brownish as they mature.
