Troubleshooting
Breadnut problems — and how to fix them
Breadnut (Artocarpus camansi) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Fruit borer (Margaronia spp.)
Caterpillars tunnel into developing fruits, causing premature drop and internal decay. Bagging young fruits provides physical protection in small orchards. Maintain good sanitation by removing fallen infested fruits and destroying them away from the tree.
Phytophthora root and crown rot
Poorly draining or waterlogged soils allow Phytophthora cinnamomi and related species to infect roots and the crown, causing sudden decline. Plant on raised mounds or ridges in low-lying areas; do not mulch up against the trunk, and ensure excellent drainage from the outset.
Wind damage to large fruits
Fruit clusters can reach 4–8 kg and are vulnerable to dropping prematurely in strong winds. Protect young trees with windbreaks while the trunk thickens. In exposed locations, staking fruit clusters or selecting a sheltered planting site reduces losses.
