Plumcot Fruit Oozing Clear Resin: Plum Curculio Beetle Damage

Plumcot fruit shows small holes with clear liquid that hardens into crystal-like droplets. This resin is the plant's defense response to wounding—typically from insect boring.

Identifying the Culprit

The most common offender is the plum curculio, a small weevil that lays eggs in developing fruit. The larva bores inside, triggering resin flow that hardens into the observed "clear crystallized sugar" appearance.

Management Steps

1. Search "plum curculio" images to confirm.
2. Take affected fruit to a local garden center for insecticide recommendations approved for your area and crop.
3. Apply treatments at proper timing (usually petal fall and shuck split) for effective control.
