In organic production, only two insecticides are permitted for controlling leek moth. It is also essential to properly synchronize sprays to reach the larvae before they burrow into the leek leaves. Despite their best efforts, producers suffer considerable damage and yield loss. So it is important to examine other methods of combatting this major pest of organic garlic, onion, and leek in Québec.
