Can I Mix Immunox and Malathion?

I sprayed most of my peach and plums trees right after petal fall (last tuesday) with Malathion. I had sprayed awhile ago with Immunox. Fruitlets are now at about pea size or bigger. I was going to do my next spray at 10 days but it has been raining like crazy so I’m going to monitor the trees in the morning for PC bites and might spray a day or two earlier. Anyway, I’d like to spray Immunox (Myclobutanil) and Malathion at the same time (mixed together). I assume this combo is okay, but haven’t been able to find much useful info online confirming or denying it. Has anyone used this combo in the past?
