No Spray Apple List

Summer rots for apples are not a problem for commercial growers. In general, they spray more into Summer and are able to control the Summer rots. Home growers spray less and not much in Summer so they often suffer from Summer rots. Also the farther South you are the more likely Summer rots will be a problem.

Since commercial growers don’t have problems I don’t think there is much research into Summer rots and that translates into fewer apple cultivars having ratings for Summer rots. This is true for other “minor” diseases like frog eye leaf spot.

This thread talks about Summer rots and has two lists of apples with Summer rot resistance levels.
