Fahrenheit Herbicide, manufactured by Quali-Pro, is a 38% water-soluble granule herbicide for the control of over 100 broadleaf and grassy weeds in labeled warm-season turf grasses.
This easy-to-use formula provides visible activity in as little as 7 to 10 days. Fahrenheit Herbicide contains two active ingredients: metsulfuron-methyl 5% and Dicamba 33%. This combination is a very effective killer of invading annual and perennial broadleaf weeds and certain grassy weeds.
Fahrenheit Herbicide is a recommendable, economical product that can applied in low doses for complete, affordable weed control.
Tools Needed
You will need to mix the product into a sprayer of your choosing, such as a backpack sprayer, handheld pump sprayer, or a professional spray rig for large-volume applications.
How to Use
- Step 1: Determine how much Fahrenheit Herbicide to use by measuring the square footage of the treatment area. To do this, you will need to measure the length and width of the treatment area in feet and then multiply them together (length X width = square footage). For acreage, take your square footage and divide it by one acre (square footage / 43,560 sq. ft. = acre). For spot applications, apply 0.2 fl. oz. of Fahrenheit Herbicide per 1 gallon of water per 1,000 square feet. Larger broadcast applications will vary between 3 to 12 fl. oz. of product per 20-80 gallons of water per acre.
- Step 2: Fill your sprayer tank with half the required amount of water and then add the proper amount of Fahrenheit Herbicide. Fill the sprayer the rest of the way with the remaining half of the water. Close the sprayer and shake it until the product is well-mixed.
- Step 3: Spray the target weed, using the fan spray setting to ensure even coverage. Check back after 7 to 10 days and reapply if necessary to achieve complete control.
Where to Use
Use Fahrenheit Herbicide as a foliar spray on warm-season turf on residential and commercial lawns or commercial properties such as sod farms, sports fields, parks, campsites, recreational areas, roadsides, school grounds, cemeteries, and golf courses (except golf course greens and collars).
When to Use
Fahrenheit can be used in the spring, summer, and fall if temperatures are 50 degrees or above.
Safety Information
Fahrenheit Herbicide is safe to use around pets and children when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Do not allow people or pets to enter the treated area until sprays have dried.
Special Considerations
One bottle of Fahrenheit can treat one acre. Fahrenheit can deliver results in temperatures as low as 50 degrees to be used throughout the growing season.

Worked as advertised
I purchased Farenheit specifically for spurge. It did the trick plus it killed some other unidentified weeds. It took a few weeks for me to see it working. It may have been that I did not mix strong enough or didn't spray enough.
Killed spurge plus other unidentified weeds.

Transformative
I live in FL and had been struggling to rid my front lawn of dollarweed growth for about three years. I tried all of the products recommended by my local nursery such as granular Dollarweed Control, Atrazine, etc. These products helped a little, but they also stressed and stunted my St. Augustine for weeks on end, and the dollarweed just kept coming back stronger than ever. I'd pretty much given up and had begun getting quotes for a complete kill and replace of the roughly 500sf of grass that seemed lost to the scourge. However, I then discovered some reviews on-line about Fahrenheit. I had nothing to lose at this point, so I decided to make this my last stand. I'm really happy that I did. I used just .13 oz in a one gallon sprayer, included some dye to avoid over-treatment and put up a little cardboard barrier to protect my mulch bed plantings. I am so impressed with the results. The dollarweed was COMPLETELY wiped out completely within a couple of weeks, my St. Augustine never suffered, and it's now been close to 9 weeks with next to zero weed recurrence. I have since treated with a standard pre-emergent and my front lawn now looks super healthy again. Fahrenheit saved me from spending about $1K on new sod installation! I remain vigilant and ready to hit that dollarweed with Fahrenheit again if it ever rears its ugly head again. I've got plenty left!
Very effective against dollarweed, straightforward to apply, takes it easy on St. Augustine, longer lasting that anticipated, and very economical!
Recommend using a dye to avoid over-treatment, can't spray along desired plants/flowers without using some form of protective barrier

Seems to work
I have only used it once for my dollar weed and it appears to have killed about a third of it. I was told it would take probably 3 sprayings so that appears to be correct.

Amazing Result
This product is amazing.. I had spurge weed taken over my entire lawn. I tried this and in first application only most of it died..I had to use second application as weed was spread everywhere
First time when you spread it it takes 7-10 days to start seeing the results I was really shocked 70% of the weed died and after second application it's almost gone.. strongly recommend ?..
Make sure you dont water and there is no rain forecast after the application for at least 4-5 days

More Time will Tell
I used it four days ago, but no decline on the spurge yet. Upon calling the store, I was told it may take up to 3 weeks. I will apply it again and hope it kills the weed. I will also add the surfactant (Dawn dishwashing detergent for better results.

Q:On one of your videos on controlling/removing Virginia Buttonweed, it says to use either Top Shot or Fahrenheit on St. Augustine and Centipede grasses. I have St. Augustine Floratam in Texas and the details for Fahrenheit shows incompatible grass types are St. Augustine and Zoysiagrass. Can you clarify if this will harm my St. Augustine Floratam lawn? Thanks4/21/24A:It can be used on st augustine grass but you need to be careful not to mix it to heavy or overapply as then it will damage it. Even if used at low rate some chlorosis (yellowing) will occur but it will bounce back. The incompatibility is more of a precautionary warning when extra care should be taken.
