Can I mix CoRoN 18-3-6 Plus 0.5% Fe with Q4 herbicide to do spot spraying with a 4 gallon back pack sprayer?

Just wondering if I used a back pack sprayer and went over a lawn to spray for weeds if I could use this and fertilize at the same time? Also how thick does it need to be applied? Generally when I spray for weeds I just mist the yard or the spot I am spraying. Just wondering if I did this with the fertilizer if it would work? Any info about mixing this with herbicide in a back pack sprayer would be greatly appreciated.


Yes, you can use a 4 gallon backpack sprayer with CoRon 18-3-6 Plus 0.5% Fe and Q4 Plus Turf Herbicide. Be sure to do a small tank mixture first to ensure there is no clumping between the two products. This should be applied to the point of runoff. Be sure the soil is not muddy after applying the products. The mixing rate for these products will depend on what type of turf grass you have.
