Control citrus leafminer on citrus leaves.

Citrus leafminer (Phyllocnistis citrella) tunnels through the young leaves of citrus trees which creates silvery lines. Finally, it curls the leaf into a shelter and pupates within. This can severely distort the leaves, but mature trees are not likely to be seriously damaged. To protect young trees, spray new growth thoroughly with Searles Pest Gun.

The presence of this pest can be identified by the silvery lines it leaves on leaves. These are the tunnels left by the larvae as it ‘mines’ its way through the insides of the leaf. Leafminers can cause a lot of damage to trees and the leaves will become severely distorted. When the larvae are fully grown, they curl the leaf edges and shelter inside the curled section. To control citrus leafminer, use Searles Pest Gun, spraying the affected foliage only. Keep a close monitor for more activity and spray again whenever new leaf damage is spotted.

For a fully organic alternative to control citrus leaf miner on citrus leaves, spray with a Ecofend Fruit & Garden Insect and Scale Spray.
