In the control of the codling moth (Carpocapsa pomonella) it is important that the spray applications be timed so that there will be a maximum of fresh spray coverage on the fruit and foliage when there is a maximum of worms entering the fruit. In Missouri we are using breeding cages and bait traps to follow moth and worm development through the spring, summer and early fall, and are timing the spray applications by actual moth emergence. Results show that equal or better control can be secured with from one to three fewer applications if they are timed to best advantage. Time-to-spray recommendations are received by every apple grower in the state.
