We mix Captan and Malathion when we spray our trees.. That is what everyone advised when we were first getting started with fruit trees. If using a sprayer, make sure you shake the sprayer often to keep the solution evenly mixed.
I have no experience adding fertilizer at the same time but there are products that combine all three: fungicide, insecticide and fertilizer (often found in products for roses). I would not imagine that fertilizer would react with the fungicide and insecticide.
I decorate in green!
