April 11, 2011: Recorded Apple Pest Message in Print

Hello Apple Growers,
I found hatched winter moth eggs toay in Warwick, RI in opened red maple buds. I'd looked several times over the last couple of weeks, but today was the first I found hatched eggs. If your orchard is in a known winter moth infested area, apply an insecticide within the next week. Any insecticide appears to be quite effective against winter moth, the key is spraying before many larvae hatch and wriggle their way into buds. Once larvae are in buds they are protected from insecticides until the buds open. Once apple, pear and blueberry buds open, damage to the flowers has already occurred.
