The citrus industry says it a disease has returned that can cause fruit to fall from trees at the earliest stage of development.

The Lakeland Ledger reports that a fungal disease called post-bloom fruit drop has returned.

The fungus causes a tree to drop the fruit just after it buds.

The fungus returns as growers keep trying to battle citrus greening, which can also cause fruit to drop prematurely.

Post-bloom fruit drop hasn’t been a problem in Florida in twenty years.
