Leaf Miner, huh? What’s a Leaf Miner?

Jan  My organic garden plague is leaf miners! Suggestions?

I get this picture in my mind of a small creature with a miner’s hat and a pick. In reality, they are the larvae of a fly that burrow through leaves. Usually the damage is not aesthetically pleasing. However, if left unchecked, leaf miners can cause major damage.

Here are some solutions:

  1. Monitoring – kill leaf miner larvae in the leaf if possible.
  2. Nutrition –  a healthy plant has thicker, healthier leaves. Plus, biochemically, the plant is not as appealing to the leaf miner.
  3. Floating Row Covers – creates a mechanical barrier that keeps the leaf miner fly away from the crop.
  4. Parasitic Wasp – Diglyphus isaea is a parasitic wasp that prey on the larvae of the leaf miner fly.
  5. Neem Oil – Neem Oil may break the life cycle of the leaf miner larvae to keep them from growing to maturity.

Getting rid of this pest takes diligence!
