Control strategies against leek moth in organic production

Description

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.

Objective(s)

• Evaluate effective and economically viable control strategies for leek moth that are healthy for both humans and ecosystems
• Evaluate leek moth control strategies in organic leek production based on data already available in Québec, other Canadian provinces, the U.S., and elsewhere in the world.
