apple tree insecticide for codling moths

[justsmith777]

I have problems with Plum curculio and codling moths. I'm currently using Sevin 100530124 GardenTech Insect Killer Concentrate. It did well on the plum curculio, but I think my timing was bad on the codling moths. I would like to have another insecticide in order to alternate applications to prevent the insects from building immunity.

I have several different varieties of apple trees, so the bloom stages are different. I've just let the early blooming tree be the guide.

Any suggestions would be appreciated. Thanks
