Prime Source Celsius WG - 0.226 oz Easy Mix Packet-Post Emerge Weed Control

Great product on my bermuda/centipede mixed lawn. Followed the application chart and waited. It has been 3 weeks and the target weeds are dead or in great distress. Be patient and give it time to work.

Fantastic product, my zoysia lawn had a decent amount of Virginia buttonweed which is a perennial and tough to eradicate, the weed and feed I was using wasn’t doing the trick so I tried this and 3 weeks after putting it down so many of the weeds are gone, second application after 3 weeks took half as long to spot treat as the first time because there are so many less weeds. Also, the zoysia took it like a champ, the spots of grass that got sprayed ended up being only slightly less green than the rest of the yard and bounced back in about 2 weeks/3 mows. This second application will have them almost, if not completely eradicated.

This stuff worked great, I put it on my Dallas Grass and about an hour later, we had a sudden down pour, I thought for sure it would have washed away but the Dallas grass had stopped growing. I used weed kill that would not kill your lawn with no success, even was spraying grass killer having all these brown spots in my yard, I am very pleased and will continue to use this product.

The most effective selective herbicide I've used. Get yourself a two gallon hand pump or electric sprayer, some surfactant, mix it up and you're ready to go. As others have said, it works slowly but it's very effective. Bonus, it's less expensive than the common brands at big box stores when you consider you get two gallons out of one packet. Be sure to use it in the right conditions (season/temperature/precipitation/wind) for best results.

Loved how effective this is. Most people, I read, mix it with certainty herbicide but that was too expensive for my individual use. Just used this handy little packet perfectly priced for a 2 gallon mix to which I added a little surfactant. Covered about 2k sq ft. It has started to kill weeds I have no idea what they are called ( mostly broadleafs). Slow acting but it surely looks like is very effective.

Hasn't worked yet. First of all, the directions are all warnings. I wasn't able to find the DIRECTIONS on how to do anything other than, don't eat it, don't put it in your eyes, don't put it in the rivers and streams, and don't, and more don't's. How about, how many oz per gallon. I finally found the line that says the package is 0.226oz. So I got out the mirror and a credit card, then split it in half (more or less) and mixed it in a 1gal sprayer. I used 1 gallon on the front lawn spraying the visible weeds and then broadcasted it all over. I mixed the second gallon and did the same in the back. It's been almost a week and it doesn't seem to be working. The weeds are rich and green. I'm glad that I didn't buy the $100 size. Yard size is typical for a single story residual that doesn't have enough room for a pool.

Easy to mix with water in sprayer bottle. Kills the weeds not the grass. And it's perfect for summer heat.

A bit expensive but it works well I use it for spot spraying burrweed patches in my St Augustine lawn. No grass damage. Other off the shelf herbicides didnt work I mix and mid strength. I add a touch of surfactant and blue dye
