Hi Everyone

I applied Scotts Halts Crabgrass in early April. I was planning to reapply Spectracide Weed Killer at the end of May. I'm planning to start using Prodiamine 65 WDG this fall. If I continue with my plan will I hit the max pre-emergent rates for the year with my plan? Should I not apply Spectracide in May and just spray Prodiamine in the fall?

These are different active ingredients. You won't hit the max for either of them.

What do you think of my plan?

It sound good. You might get better weed control with a foliar applied product than a granular.

The weed types I have in my lawn are Poa A&T, Crabgrass, CCO and other grassy weeds(I cannot identify those). What do you think would be a better pre-emergent and weed killer plan? The last thing I want to do is to apply pre-emergents and killers that wont work for my lawn. I also locally spray Bayer weed killer

Poa A - Tenacity at 2oz/acre rate 2-4 applications every ~10 days
Poa T - Round up (or round up + AS)
Crabgrass - WBG + Crabgrass preventer or anything with quinclorac
CCO - WBG CCO
other grass weeds - likely round up is the other option

You already applied a PreM in spring (pendi) and will use Prodiamine in the fall (great for poa a next year). Dithioypr in the late spring/summer could help with any crabgrass that is young, but quinclorac will also work.

Pretty much the plan I have been implementing. I will switch to two applications of Prodiamine in the spring and the fall next year. I'm hoping to get rid of the Poa A.
