Rated 5 out of 5 by from Worked Great This worked great to eliminate all unwanted weeds including the purple stuff that 24D did not kill last year. We are very happy with the results and will use it again next year. I used the entire gallon on approximately 1.2 acres.

Rated 4 out of 5 by from Kills MOST weeds... Does well on my lawn, not harming the grass at all. It kills most weeds but has little impact on broad leaf clover for some reason. It kills the small leaf clover just fine, though. I have bought this many times and am pleased with it overall.

Rated 4 out of 5 by from Trimec Did Not Kill Henbit Used as recommended, except at a rate of 125% because of application speed being to slow. Killed almost everything but Henbit. It wilted but did not die. Studies found Henbit is best controlled in the late fall to winter months. Have used the professional version, Gordon's Trimec Classic, in the past. Think it worked better.

Rated 3 out of 5 by from Works great-FILTER IT FIRST The product itself works well. I bought a bottle last fall, and it settles with a LOT of sediment. It clogged my Fimco sprayer inlet. I had to drain the tank through a paint filter to filter out the sediment in order not lose the whole tankful of product

Rated 4 out of 5 by from Weed killer This product worked well after 3 applications. We knocked down the weeds then sprayed them.

Rated 5 out of 5 by from YASSS LIFE CHANGING! Literally killed all my weeds and other pesky plants in like a day. Thank you landscape gods for creating this concoction. Legit best ever.

Rated 1 out of 5 by from No good. I followed directions. Sprayed twice and all it did was take care of the dandelions and nothing else. I still have clover and a ton of other weeds.

Rated 5 out of 5 by from Kills difficult weeds without harming grass While there are a number of herbicides that work on common lawn weeds, I found them ineffective in killing japanese grass. Trimec worked! It also killed mocking strawberries (and all common weeds) in my lawn without hurting the grass. I used a solution of 2 OZ/Gallon of Trimec concentrate and 1.5 oz/gallon of MSO (Methylized seed oil). TSC prices were almost half of other vendors that showed up in my online search. Highly recommend the product and TSC.

Rated 5 out of 5 by from Effective, affordable weed killer (not crab grass) Have 10 acres infested badly with all kinds of weeds. Trying to get my Bermuda grass to be the dominant specie, instead of the weeds. Put down one application, and in 3 days 90% of the weeds were starting to wilt (except crab grass. You need a special chemical for that). After a week-ten days, parts of my yard were brown, where the weeds were dead, and no Bermuda was able to exist. Now a month later, my Bermuda is starting to spread into the "previously weed infested areas". One important note. BE SURE to use a surfectant in your sprayer. You can buy a 16 oz bottle for $12-$13, or you can use ½ oz of Dawn dish soap per gallon of mixture of Trimec and water. This will definitely make the weed killer more effective. Most people who don't have good luck with spray chemicals eliminate or disregard the surfectant. Dawn's cheap. Trimec is a little more expensive...don't be penny wise and pound foolish. Use the surfectant. It works! Also, depending on your specie of grass, be sure to follow the mixture recommendations on the label. Bermuda is a hardy grass. St Augustine and Centipede are not.

Rated 5 out of 5 by from Patience is key You must be patient. I used a product by Bayer got very expensive. Took 7-10 days to take effect but when it did wow. Same here with Trimec, this is not a quick kill product, but very effective when it starts to work.

Rated 4 out of 5 by from This product works well I searched on line to find a weed kill that will not harm grass in the peak growing season. Gordon's trimec worked very well. All customers are very happy. And tractor supply keeps it in stock.

Rated 5 out of 5 by from Great product. Excellent broadleaf control. We bought 3 acres that had not been managed for some time and is disected with various flower and shrub beds so we had to be careful with our lawn sprayer applications. Trimec was the perfect answer. We're in our 2nd year and what a difference. Our mid-season application with the added crabgrass control is well worth the extra $10. And read those directions. If you started out like we did, with more dandelions and clover than grass, do that fall application in October. You'll be glad you did come spring. Thanks Gordon's!

Rated 5 out of 5 by from Excellent Product I've used 2,4-D for years... When my supplier went out of business 3 years ago I did some research on where to start buying it. I don't think much of the box store watered down stuff.. I ended up buying the Trimec and applied it at the same rate as I had the 2,4-D... I kept my eye on it as I sprayed about 75 gallon the first time on a lot of ground.. I didn't appear to doing anything at first and then it took ahold and wow... I got compliments from the neighbors because it gets rid of more broadleaf than just the 2,4-D did.... I had the cleanest grass around.. This will be the 4 th year of using it and will always use thing people don't realize is even with generic roundups ... The product only works as fast as the green stuff is growing... They aren't an overnight product and you have to know how to mix it and apply it....I RECOMMEND THIS FOR A CLEAN AND THICK YARD ... Use a little dawn dish soap when you apply. For every 25 gallon I gave it about 3 a little hand sprayer it only takes a dab...

Rated 1 out of 5 by from Complete waste of time and money Mixed as directed. Applied with tank sprayer. Weeds are thriving. No effect. None. I recommend straight water. Works just as well and costs less.

What is recommended wait times between applications? We have a lot of Creeping Charlie, wondering if safe to apply second fall application. Is it ok to apply in 40's/50's (F)?

Allow at least 3 weeks between applications. Trimec Lawn Weed Killer works best in daytime teamperatures between 60-85 degrees.

For an Ortho hose end sprayer would you use a setting of  “1 oz” for Bermuda grass?    Many thx

Asked by: Scott A
The setting for a hose end sprayer for Trimec Lawn Weed Killer is 1 oz. You should be applying 4 oz of product for every 1,000 square feet of lawn for your best results. Contact our product specialists at 800-884-3179 if you have more questions.
