The Green Cabbage/Kale Caterpillar: A Vegetable Garden Pest
Identifying and Hand Picking
If you see the white butterflies in your garden, you will soon have green caterpillars. They will eat holes in your cabbages, kales, and related plants. This Knol is about identifying the pest and removing it by hand. I wrote another Knol on BT control of caterpillars which I linked to this one.
