Why are my apple trees wormy every year?
Rate This FAQ
“Worms” in apples are codling moth larvae. Codling moth may spoil 90% of the fruit crop. Spraying with approved insecticides is the only effective control and timing is essential. Starting 10 days after petal fall or based on trapping information, apply sprays according to protection interval of chemicals used, and continuing through the first week in September. Follow label instructions. Refer to the Utah State University Integrated Pest Management Fruit Tree Advisory website for your area’s projected spray dates.
