Can I use this to spot treat poa aunna in my Tall Fescue in March??

I have used pre-emergent (Lesco) in the past in the fall for the management of Poa annua. This year, I used that plus Prodiamine 65WG to no avail. The poa annua is taking over!!!! I bag my clippings and can't seem to control this horrible grass. Help!! I live in Charlotte, NC

Answer:

Pre-emergents like Prograss EC Herbicide are applied when ground temperatures are consistently at 55 degrees. Because that exact time varies from region to region, we suggest speaking to your county extension office for timing in your area. Please note, Prograss EC Herbicide may be applied to residential lawns by licensed or certified applicators. Prograss EC Herbicide is not intended for use by homeowners. Please check out our Poa guide here for more information: https://www.domyown.com/poa-annua-identification-guide-a-569.html
