You may want to switch April and September around as Barricade in Sept wont control crab grass, We prefer fall applictaions for broadleaf weed control,(weed and feed)Most broadleaf weed control impregnated on dry fert do a lousy job and you have a lot more broadleaf options if you spray (unlike crabgrass control)Scotts brand normally is too fast a release to be a good value for our cool season turf, yours may be different. I would lean towards talking to JDL especially about what type of annual grass you have and germination dates.A good site for information is
http://www.lawnsite.com but be aware if you post they will come down hard on most.I do mostly "search" there as the personalities can leave a lot to be desired at times on that site.
