Jim from Oshawa, Ontario writes

What is the best post-emergent pesticide for spot or blanket spraying cool season turf?

I am looking for a post-emergent herbicide that contains quinclorac, triclopyr, fluroxypyr and carfentrazone.

Answer:

We do not have a post-emergent herbicide that will contain all 4 of the active ingredients you mentioned.  Without knowing what weeds are being targeted, it is hard to make a recommendation. In most cases, tank mixing two herbicides is allowed if permitted on the product labels. You would follow the most restrictive label in regards to tank mixing.  Q4 Plus tends to be the most popular for broadleaf weed control in cool-season turf. Here are some other options.  QuickSilver Herbicide contains Carfentrazone-ethyl Ferti-lome Weed Free Zone contains 2,4-D, mecoprop-p, dicamba and carfentrazone-ethyl.  E-2 Herbicide contains 2,4-D, Fluroxpyr, and Dicamba Q4 Plus contains 2,4-D, Dicamba, Quinclorac and Sulfentrazone  Solitare Herbicide contains Quinclorac & Sulfentrazone.
