I also need a weed killer that can be used in the cold weather. My question is how low can the temperature be for this to still be effective????
admin says
Patty,
If you review the label, you’ll notice they don’t list a specific temperature. They only word it saying “proven cool weather performance”. But having used this product quite a bit the past few years, here’s what I can tell you based on personal experience.
First, it will definitely work down to 45 degrees. I say this because I’ve use it when the temps have been 45-46 and within a few days, I’ve seen the targeted weeds start to die.
Now is it possible it can still kill weeds at 40 degrees or colder? I don’t know. And I don’t think I’ll be using any in such cold anytime soon so I can’t even run a test to see.
Hope this helps!
Cheers,
Jonathan

I want to kill fescue and rye grass that accidently got into my rock pathway when over-seeding. Will this kill it ? I want to use it in the cooler weather (45-50 degrees). Thank you.

Fredrica,
This is not a good option. Here’s why. Basically this product was created to be used over “good” turf like fescue so its not likely strong enough to do damage unless you over apply it which is not efficient. But we have a couple of viable options.
The first is the Knock Out aerosol. One can can treat up to 150 sq/ft and it will kill everything you spray regardless of the temperature.

The second option would be the selective herbicide we carry called Grass Killer. Designed for use in flower beds, it will kill both fescue and rye. Typically it works best when the temps are 65+ but if you add some Herbi-Oil to the tank mix, you should get positive results. The Herbi-Oil will get the product into the ground and foliage much sooner even though its still cool so you’ll achieve positive results. But instead of it taking 7-14 days, it will most likely take a bit longer.

Now to prevent this in the future, it would be smart to treat the area before seeding with Pramitol soil sterilant.
