Thats a good question, I never found a complete answer to it but somewhere I read it would not be completely negated by other sprays.
In general Serenade is very weak, I don’t think its worth spraying on bad rot. I tried for 15 years and now I rarely use it. Tri-Tek oil is better if you want something low-impact. Or sulphur.
In general your sprays are not what I would call a good mix for brown rot, I would get one of the more effective things mentioned above and not captan. The Monterey fruit tree spray is not really doing anything for peaches, those insecticides are so weak that they don’t kill much more than aphids. If you want to do low-impact bug control use Surround, Bt, and/or spinosad instead.
Here is my low-impact schedule if you didn’t find it already:
