cool season grasses ... what is the proper mix ratio for a 2 gal. tank sprayer? Does freezing affect it (if stored in winter in unheated garage)?
The Dismiss Turf Herbicide is not labeled to kill poa annua but it is not listed as a grass that it is safe to be sprayed on. Tolerant cool seasons grasses are : Creeping Bentgrass, Kentucky Bluegrass, Rough Bluegrass, Fine & Tall Fescue, Perrenial Ryegrass. No product should be stored in an area where it can freeze or get too hot. Insecticides and herbicides need to be stored in a temperature stable environment out of direct sunlight to sustain the longest shelf life and strongest potency of the product. A product that is safe on several cool season grasses and will cover broad leaf weeds as well as grassy weeds and Poa Annua would be the Echelon 4SC. Echelon 4SC is a selective/post emergent product like the Dismiss but better suited to your needs. You can review the product label for dilution rates for your type of yard. Please let us know if you have any other questions.
