Bacillus Thurengiensis is sold as Caterpillar Killer.
Spraying every three weeks, starting in June is very effective.
Earlier if the butterflies show up early, as they did here, in '09, BIG time.
Regular spraying creates layers of protection.
Even if a worm begins to burrow into the bud, he'll soon run into the spray, which, once shaded inside the bud, will remain effective for months.
I found worm damage on about a dozen buds this year, due to missing a spot for one spray.
I found no live worms, and the total loss was less than 1/4 ounce.
I can live with that.
