This morning, Saturday, September 12, 2009 we saw what appear to be Cabbage Looper worms in the Tower greens tub. We picked off about a dozen (they went over the side, where most likely they will join the Circle of Life via Brother Crow.)
They seem to have concentrated on the chard, but a few of the lettuce mix plants have bit marks too. Also, there are round, dark green nodes on the tops of some leaves that may be eggs.
What's the next step? This effort is strictly organic; we have no way of knowing when or if people who are sensitive may wander by or be recipients of the food via the food bank, we don't want to poison our community on general principles, and we don't want to disrupt our local micro environment which is already pretty hacked up by development. This is a test of brains: are we smart enough to figure out a solution?
