Cabbage Looper & Cabbage Worm
Description: In most of the country it is almost impossible to raise any vegetable in the cole family (cabbage, broccoli, cauliflower, kale, etc.) without controlling these green pests, 1-1/4″ to 1-1/2″ long. Presence of white or yellow butterflies signals start of infestation. These cabbage pests can defoliate plants very quickly when fully grown. They eat holes in leaves, leaving green excrement.
Solution: Super-Light Insect Barriers are excellent to block infestation. Trichogramma control these cabbage pests; they lay their eggs in, and destroy, the eggs of moths and butterflies which would otherwise hatch to become cabbage worms and loopers; but they do not kill the pests themselves. Once these pests have hatched, use MVP II or Bt ssp. kurstaki for complete and rapid control of cabbage worms and loopers. Feeding stops almost as soon as Bt is eaten, and the worms die within 48 hours.
