Can the apple trees be sprayed to control the maggots?
Yes, a spray program can be initiated in late June and continued until early to mid August depending on the maturity date of the apple. Usually we recommend spraying the apples every 7-10 days with Sevin, Malathion, Diazinon or Methoxychlor. This would keep the adult insect from laying eggs into the fruit. Once the eggs are laid no control measures will work.
