Can I mix Maneb and horticultural spray oil in the same tank for use on apple trees for fungus and bugs?

My recommendation would be: don't do it. Interactions between pesticides can vary from none to serious. Efficacy of the pesticides may be reduced by mixing. Mixing may damage your sprayer. Timing of applications is different for different pesticides.

In any case, read the labels. The labels are the law. Here is a reference:
