Cabbage loopers are emerging, so it’s time to start adding BT to the rotation! Cabbage loopers are the smaller white moths and their caterpillars can eat/ruin leaves of plants. They especially like cabbage, kales, collards, broccoli, and brussel sprouts. The green caterpillars are what cause the damage and they are the target for BT application.
BT is a bacteria (organic) that targets caterpillars without harming beneficial insects. I sprayed it on my plants in the evening and made a point to spray all areas of the plant. This product must be ingested to work, so application all over the plant is key.
If you’re seeing cabbage loppers I highly recommend starting BT now, and apply as needed through the season.
