We do our normal tilling in our tree rows generally once a month beginning in May with our Weed Badger. We catch the end of June drop that would get any PC eggs between 550 DD and 800 DD, then again when the PC pupae are in the soil if any eggs were missed, generally from 900 DD through 1200 DD. That would be the only time tilling would be beneficial against PC. The critical control period for codling moth eggs is around 250 - 300 DD which is also just after petal fall for us and a critical control period for adult PC. I use Calypso, which is an ovicide for CM and is very effective against PC just after petal fall. With our cultural practices and Calypso we have been able to control PC for the past 2 seasons since phasing out Imidan completely. We are now organophosphate free!

Murphy said he controls curcullio by tilling under the trees in Spring and Fall. So why spray? I tilled last Fall and will do so again in a day or so.
