Monterey Sucker Stopper RTU, Ready-To-Use Sprout Growth Regulator, Controls Regrowth of Tree Sprouts, 16 oz

I was super reluctant to buy this product due to the price. There were cheaper products that I was tempted to buy. It got good reviews so I went for it. I have been pleasantly surprised at how well it works. I have used it on different trees (crepe myrtles are the worse!) and it has kept the suckers away. I saw comments about how thick the solution is and how it does not spray well but I did not have any problem. I think if you shake the bottle frequently it helps the spray mechanism. Pricey, but worth it.

I was hesitant to order due to the price, but this stuff works! I'll save hours and hours of the never-ending suckers that come out of my olive tree! Ordering a second bottle for some of the areas I missed before, then I'll never have to trim again.

I have a flowering crab tree that is prone to lots of suckers at the roots coming up at he soil level . This is the only product that stops the suckers. I cut the suckers and spray .... this takes care of the suckers at that location for at least one year. Yes it is expensive but a little bit goes a long. way..... and I can stop the constant cutting of the suckers . I will buy this again when I run out.

I have used this product to kill suckers emerging from the root lines of my crepe myrtle . It is very effective in preventing the growth of the suckers and one spray seems sufficient. My only concern is the price - very expensive per once .

Easy to use. Effective. One bottle generally lasts for a full growing season.

I tried this on two lindens which have lots of persistent suckers. It did absolutely nothing! Very disappointed in this rather expensive product. The sprayer doesn't work well. Stream mode is more of a spray making it hard to get it on the ends of the cut-off suckers without a lot of waste.

Amazon did a horrid job shipping. I ordered 2. Both were packaged together which is ok only if they are tightly sealed. One cap was lose and most of the product soak the packaging and box. Nearly impossible to clean and return. Good by $40. I don't think it's a good idea to get that stuff all over your hands!

Amazing product! Cut down an old Crape Myrtle and suckers continually popped up ( think multiple around stump). Used Sucker Stopper twice around stump (ground level) and now have only 3 that popped up. One more time and I shouldn’t have any more
