Refill Kit for use with Defenders Tomato Leaf Miner Pheromone Traps. Leaf-burrowing tomato leaf miners are a common greenhouse pest within mainland UK, causing reduced plant vigour, leaf-drop, and poor yields in salad crops such as tomatoes, lettuce, and sweet peppers. The pheromone-coated glue is resistant to drying out, soaking, and prolonged exposure to UV sunlight.
For best results be sure to hang your traps in early summer and refresh them throughout the growing season.
