I would not unless you have asked specifically what you can mix either with your extension agency or the manufacturer of the products and since one is home made and not a known to them as a control in the field or lab they will tell you no.... the Ph can make a spray totally ineffective or the
other ingredients can have a chemical reaction between the products.. we actually have to add battery acid to make the ph low enough for the spray to work for one of our apple tree sprays.. otherwise we are giving the bugs a bath and wasting big dollars to do so.
