The fact is that this so called vaccine still does not have FDA approval. It has only been in use for what 8 months? Also, there are reports of people experiencing complications after receiving the shots. Forgive us if we don’t trust it yet.
I typically like to mow the turf and let it get a days worth of growth before I spray. It makes sure that the weeds are actively growing again. As far as what chemical to use for crabgrass in centipede, Sethoxydim (Poast) seems to work pretty well with two applications at 14 day intervals...
I played baseball for New Hope back in the early 90’s. Kirk Presley was a phenomenal pitcher. He could also hit pretty well also. During one game against them at home in 1993, he hit a grand slam over my head in left field. I’m not sure if that ball has ever landed !
It looks like Dollar Spot disease.
The continued wet conditions are causing the disease to ramp up. You need to get a fungicide called Iprodione( Clearys 3336 ) and spray it on 14 day intervals.
