For Summer rots there are a couple of different solutions-
-
Plant cultivars that are resistant to Summer rots then you don’t have to spray for them. This is the best solution in areas that have high Summer rot pressure. Generally, the farther South you are the more rot problems you will face.
-
Spray for Summer rots. To do this you will need to do more sprays that extend farther into Summer. You may also need to tighten up the spray interval.
-
You can bag the apples. Ideally, you would bag the apples with ziploc bags a couple of days after a fungicide spray.
This thread gives two lists of apples with their resistance to Summer rots. One list is from a book and the other was provided by Scott and is based on his experiences. The first post in the thread has links that will help you identify the various rots you may have on your apples.
I am able to control flyspeck and sooty blotch with bagging. You maybe able to do so as well. Although some people on the forum haven’t had good luck with bagging. Here is a study of bagging of apples.
