Honey Locust Saplings #873584

Asked June 18, 2024, 10:54 AM EDT

I had a honey locust tree removed from my suburban/neighborhood yard a couple of years ago. I now have several pesky saplings that grow each summer. Based on my research, these are coming from the buried roots (the stump was removed and planted over with grass) and can be treated with picloram which can be found in Dow Grazon P + D. I can purchase this at Rural King, Tractor Supply, etc. Do I need some sort of applicator license to use this product? I would obviously not be spraying a large area, just 40 or so saplings in about a 15-foot square area of my yard. I would only spray the saplings, not the area as a whole (unless you think I should spray the whole area??). I would appreciate some guidance on this -- best product and place to buy, am I allowed to do this as a homeowner or do I need a license, any other tips you can give me. Thank you very much in advance for your assistance!

Greetings,

Safe use of pesticides including who can use them, what they are allowed to be used on, and how to apply them can all be found on the label on the product.  Any person who applies pesticide is required by federal law to read, understand, and follow the label.  I do not have any specific recommendations where you should purchase the product, just make sure you read, understand, and follow the label guidelines to make sure that if you are allowed to do so, you do so safely and legally.

Good afternoon and thank you for your question.  You must be a licensed pesticide applicator to purchase and apply Grazon P+D, since it is a restricted use pesticide.  I would encourage you to reach out to a landscape company that is knowledgeable in both plants and pesticide safety.   You could also use a non-selective herbicide to kill the saplings but you'd need to be careful to avoid spraying your grass as will will kill everything.  Please read any pesticide label prior to making an application. 

Thank you.
