Application Notes

Surmise Pro is a foliar-active herbicide and works best when weeds are actively growing. Thorough spray coverage is important for consistent control. Weed control may be reduced when applications are made to weeds under drought stress, cool temperatures, or dense growth conditions.

For spot or directed applications, use 1 to 2 fl. oz. per gallon of water depending on weed size and growth stage. For broadcast applications, apply 32 to 80 fl. oz. per acre in a minimum of 40 gallons of water per acre. Surmise Pro is rainfast in as little as 30 minutes and up to 4 hours depending on environmental conditions, weed species, and application rate.

No surfactant is required when applying this product. Ammonium sulfate may improve weed control where hard water is a concern. Do not apply by air, through irrigation systems, or allow grazing of treated vegetation.

Great post bike ride
I have been using this Coola recovery mist for a few weeks off and on after bike rides if I can't get a shower immediately. It provides relief to my face and shoulders from the sun and drying sweat. If I use this after washing my face at the end of the day, it helps hydrate my skin just enough if I don't feel like using my heavier creams and moisturizers. Not saying one replaces the benefit of another, but if I'm looking for something lighter this relieves the tension of tight skin perfectly. I am planning on taking this for a week long camp out this summer and plan on taking this to help relieve my skin. Yes, it definitely smells a bit like chlorine but it goes away quickly. The only thing I really don't like is the pump sprayer is really not a mist, it's more targeted and instead of misting the product is little droplets it's a dense spray in a smaller area.

Versatile spray that works well for sensitive skin
Lately I've been hearing so much about hypochlorus acid and its multiple benefits and uses. Being that I really like Coola products, when I saw that Coola had made a hypochlorous acid face spray, I was eager to give it a try. I'm glad I did! As someone with sensitive skin that gets irritated from perspiration when I work out, I was hoping this spray might calm my post-workout skin...and it did. The mist comes in an attractive spray bottle. The spray that comes out is at the intensity of somewhere between a fine mist and a coarse spray; it sprays a good amount to wet your face rather than just a very fine coating. Upon spraying on my skin that was red and warm from my workout, I immediately felt a cooling effect. I wiped the spray in to my skin a bit, and it both cleared away the perspiration, and felt soothing to my post-workout irritation. It felt very different from other toners or astringents I'd used, and my face felt clean, refreshed and unexpectedly soft after use. I later tried the recovery mist on a small area of rash I developed on my neck. I had a similar experience in that it cooled the skin, and my rash appeared minimized, as well. My only issue with this product is the scent. The spray has a scent that smells like a faint version of chlorine bleach...which was disconcerting, since I'm spraying it on my face! I actually looked it up and apparently that's just the scent that hypochlorous acid has...so it's not specific to just Coola's product. Fortunately, the bleachy scent dissipated quickly. Overall, I'm happy with this product, and found it useful for my irritated skin. While I tried it for post workout skin and a rash, apparently it can be used for bites, scrapes and acne as well, so it seems to be very versatile. So if you can get over the initial bleachy scent, it's definitely worth giving a try. Priced at $20 for the 3.4 ounce bottle, which should last a while, I find it to offer a good value for the money, as well.

Surprisingly Effective for Redness & Post-Sun Skin Recovery
This stuff actually works. I’ve been using it after sun exposure, and it genuinely seems to help calm, soothe, and hydrate my skin. I usually spray it on before applying my hydrating serums and moisturizer, so it’s part of a larger skincare routine, but I definitely feel like this mist plays an important role. My skin feels less irritated, looks less red, and just overall more refreshed afterward. The spray itself is lightweight and easy to use, with no sticky residue or heavy feeling on the skin. It layers well with other skincare products too, which I appreciate. Overall, this has become a really nice recovery step in my routine—especially after being outdoors or whenever my skin feels stressed and dehydrated. Sometimes skincare products make very dramatic promises and deliver absolutely nothing but scented disappointment. This one quietly does its job.
