Depends on the scenario. You can tank mix them, but it would be for specific foliar applications as that is the only way Ferti-lome Triple Action is applied.
If you are trying to get a systemic drench for certain pests, it would be separate treatments since Triple Action is foliar only, then it would be best to apply the systemic at the base of the tree & then apply the triple action on the trunk. The product label also does not mention tank mixing and you would need to refer to the systemic product you intend to use for tank mixing instructions if any for foliar applications.
Yes, Ferti-lome Triple Action an be used on all of these tree species
