I got tired of paying a lawn service to tint my lawn every month, that adds up at $50 a whack so I decided to apply the preemergent myself along with fertilizer periodically. And I won't dilute the mixture. Results to follow.
Looks like it was advisable in 1990. Since then, they've probably determined it kills Condors or some other stupid $%!^.
Save the Condors!!!
Some chemicals have high ph, and others low.
If I remember my class right, those are the ones you don't want to mix. Nulls them, others can have a chemical reaction.

You can mix the two, just don't mix the two concentrates together outside of the sprayer tank. Barricade and Surflan both are for spring and then reapply in the fall applications.
I always use Scott's "HALTS" crabgrass preventer and put it down in mid February and have good results. I put mine down just before this last good rain. I've discovered if I wait much longer, my yard gets eaten up with crabgrass.

I like cranbgrass, it stays green longer in the hot dry months. Hopefully this year, it will takeover the rest of my yard.
I'd love to rid my yard of sand burrs, but I have no desire to add to the chemical loading of the environment by broadcast spraying of pesticides. I just go around in the late summer and pull up the SB plants by hand, and that helps control their presence. I do make sure to dispose of the plants where they can't germinate!
We're talking herbicides, not pesticides.
Herbicides are a class of pesticide.
