Pomegranate wilt causes sudden yellowing and drying of one side or the whole plant and is linked to soil-borne fungi and often nematode and borer damage to roots, while aspergillus and other fruit rots attack cracked or insect-damaged fruit. For wilt, use clean planting material, avoid waterlogging and root injury, manage the shot-hole borer and nematodes that open the door to infection, and remove and destroy severely wilted plants to protect neighbours. For fruit rot, prevent fruit cracking and borer entry through steady moisture and bagging, and harvest and handle fruit carefully. There is no easy cure once wilt is advanced, so prevention is key. For soil treatment and an integrated plan, confirm with your local KVK or the pomegranate research station.
Borer and root damage were feeding our wilt problem. Once we controlled the shot-hole borer and stopped water sitting near the trunk, fresh wilt cases reduced.
When a plant wilted badly we removed and destroyed the whole plant including the roots rather than letting it sit and infect the neighbours. We also did not immediately replant in the same spot without treating the soil as the research station advised. Leaving a dying plant in the row just spread it down the line in our experience.
The aspergillus and fruit rots came in through the cracked and borer-holed fruit for us, so controlling the cracking with steady moisture and bagging the fruit cut the rot a lot. A cracked fruit in the heat is an open door for the rot fungus. Harvest and handle the fruit gently too, because every bruise and wound becomes a rot spot in storage and transit.
Controlling the shot-hole borer and the root nematodes was what slowed our wilt, because the borer and root damage open the door for the soil fungus. Once we managed those and stopped water sitting near the trunk, fresh wilt cases dropped. Get the integrated plan from the pomegranate research station because there is no easy cure once wilt is advanced.
We never replant immediately in the spot where a plant wilted out without treating the soil as the research station advised, because the new plant just caught it too. Removing the whole infected plant including the roots and destroying it protected the neighbours. Leaving a dying plant in the row spread it down the line for us.
