I also use about an 8 step program that works great. I don't use any one program in particular like Scotts. I may try scotts next year to eliminate spraying of weed control (NYS has a tough new law about neighbor notification for spraying, but not granular apps.)
Here is my own custom plan (I probably shouldn't tell you this as a trade secret, but I'm in a good mood!)
1. Spring clean-timing is key for pre emergents.
I lime, fertilize, and apply a pre-emrgent for crabgrass, I used Pre-M w/fert for speed/ease. Use Tupersan if seeding.
2. Early-Mid May- Super trimec spray for weeds.
3. around Mem. day fertilize again, maybe another shot of pre-M
4. June Insect Control
5. June/July if needed-fungicide, maybe 2 applications
6. July-Crabgrass an Nutsedge spot treat as needed
7. August grub control
8. Labor Day- fertilize again
9. Broadleaf control again as needed. 3-4 weeks before seeding.
9. Very Light fall fertilizer and lime near end of season w/cleanups.
The dates will vary with your location and weather conditions. Products may vary also. Get pre-M down before Forsythia blossoms fade (this is called a phenological indicator).
I hope this helps.
