However this is an expensive option that leaves you at the mercy of waiting for weekly deliveries to control your greenhouse pests.

Mass trapping through traps, lures, or trap plants can be an effective strategy for thrips. We’ve already seen that mass trapping cards REALLY help with this pest (more on that, later). And, it seems that trap plants may also be an effective strategy when used properly in vegetative crops.

Read on for what we did and how to implement it on YOUR farm.
