Looking to blanket spray backyard with Demon Max, Nyguard, and Celsius WG (inc. Non-ionic surfactant)
As long as there are no specific instructions on any label to not mix a herbicide with an insecticide or vice versa, you can. Also, as long as you're applying the right amount of Celsius Herbicide per 1,000 sq. ft., you can mix it with Demon Max and Nyguard IGR. If you do end up mixing them, we recommend to follow the most restrictive label.
