Peach Tree Borers: Gummy Sap and Grubs at Base

Two peach trees have sparse leaves but set fruit. One exudes clear gummy sap at the base; probing revealed a grub-like worm. The gardener fears tree loss and spread to a new planting.

Diagnosis: Peach Tree Borers

The sap and grub confirm borer infestation—likely lesser peach tree borer or peachtree borer. These larvae tunnel in the cambium, disrupting vascular flow.

Immediate and Long-Term Actions

• Mechanical: Use a stiff wire or needle to probe and kill larvae in active holes.
• Preventive: Apply Atomic Grow (organic) to boost tree health and deter reinfestation.
• Monitor: Check new tree regularly; borers attack stressed trees.

Why Trees Are Vulnerable

Trees with sparse foliage are already stressed, attracting borers. Address underlying health (water, nutrients, drainage) alongside direct control.
