...Specifically we have cabbage loopers… nasty, voracious little buggers. I wish I’d take a before pic of these purple cabbage plants; they were quite healthy …were being the operative word in this case. 3 days ago they looked a lot like the ones in the Cat guard post…those are in front yard and for some odd reason completely escaped the onslaught.
—BT….Bacillus thuringiensis var Kurstaki, a naturally occurring bacterial insecticide. After consuming Bt, caterpillars stop eating and die within a few days. Controls tent caterpillars, gypsy moths, cabbage loopers, tomato hornworms and other leaf-eating caterpillars. Derived from natural ingredients and does not remain in the environment for long. May be used up to the day of harvest.
I was so intent on squishing the invaders that I forgot to get a photo of the green monsters. More info on loopers can be found in this article from Organic Gardening. Hopefully the plants will recover and I can post pics of the patients well on their way to a long and healthy life….until we decide to eat them :)
