Bonide Sucker Punch, 16 oz Ready-to-Use Spray, Control Unwanted Plant Sprouts, Plant Growth Regulator for Home Garden

I used to have two mature Callery pear trees (Pyrus calleryana), a deciduous tree native to China and Vietnam. They were planted by the home’s previous owner. While they certainly provided shade for home and lawn, not to mention a beautiful fiery display in the autumn (and a foul dead fish odor in the spring), they had to go. These trees are fragile and break, and destroy native plants nearby. They spread like weeds!One bright, hot day in September 2023, the tree in the backyard dropped three branches on the roof. Thankfully no one was hurt, and the damage was minimal. They had to go! A tree service chopped them down two days later. Fast forward to 2025, I needed something to kill the suckers still sprouting up from leftover roots in the soil. Sucker Punch does what the manufacturer says it does. With a bottle in hand, I continue my endless war with unwanted Callery suckers poking up through the soil. As the Bradford is a cultivar of the Callery, it, too, will whither and die from an application of Sucker Punch. The surrounding grass is fine.

This is the best product for sucker growth on my trees. The spray bottle is the best application method as I have found out the hard way. However, this product was packaged with flour for baking and did not understand this decision from my perspective as toxic with food?????

I had cut a massive amount of Suckers from my tree and I learned that cutting them contributes to even more suckers sprouting and it gets worse. When I cut them off, I sprayed this product on the cuts and I used a whole spray container so that was a bit expensive initially. That seemed to do the trick at least for a few months when a few new ones started to sprout again, so I'm going to repeat the same process which won't use as much as the first time, so I'm guessing this is a process that improves with each treatment. Just get them as soon as you see some suckers again. Also, trees threes produce suckers for a reason and one is when it is under stress which could be not getting enough water,

Great stuff! Once suckers are trimmed back spraying or brushing this on the tips eliminates any additional growth!

The contents of the bottle seem to work fine at sealing the wounds on the tree where suckers were cut off. This prevents new suckers from growing in their place. The problem (other than it being stupid expensive) is that the sprayer shoots out a stream of goop. There are two settings on the sprayer, one for a stream, one for a mist. Both settings produce a stream. So, I had to go find an old paint brush to spread the goop around once I sprayed it. It seems pointless to even offer it in a spray bottle if you have to spread it with a brush. Just offer it in a can (for less money) with instructions to spread it with a paint brush. They do offer it that way, but in a much larger quantity for an even stupider amount of money.Will probably try a different product next time.

I had a couple of old decrepit Black Locust trees that were had branches falling on my shed and on the electric cables cut down on my property and the stumps ground down ... If I could go back in time I would have left the stumps and treated them with stup and vine killer, but too late now. I've had hundreds of black locust suckers coming up in my lawn all summer, and have tried a couple of other grass friendly products and techniques on them, but to no avail. While I know that vine and tree killer will work on them, individually clipping the hundreds of suckers and painting the stuff on the nubins would certainly be back breaking work. That's why I really like this product. While I still need to clip most of the suckers before I spray them, the spray allows me to move more quickly. I also like the thick consistency of the product. It comes out in a stream and doesn't overspray as a result, so I'm not hitting my grass in the lawn, or plants I want to keep where the suckers come up in tight spaces in my flower bed. It also makes it easier to see what I've already hit, which is crucial when you're spraying a large number of suckers.It hasn't been long enough to see how well this product will work, I need to take some other remediation steps where the stumps were, and the suckers will slow down with the start of the cooler weather now anyway, but if there are no updates to this review (as of 08/22/2024) it's gone well :)

When you spray it on, it is a white milky substance. It looks terrible with landscaping. Not what I expected.

This stuff works great.
