Description:
In most of the country, it is almost
impossible to raise any cole crop (cabbage, broccoli,
cauliflower, kale, etc.) without controlling these
green pests, which are 1 1/4 to 1 1/2" long. Presence of
white or yellow butterflies signals start of infestation.
Caterpillars can defoliate plants very quickly.
Damage includes holes in leaves and green excrement.
