Glyphosate is the active ingredient in Roundup. With extreme overuse, maybe? Again I am talking about its use for consumer-level invasive species management or ecological/environmental applications. Glyphosate has very high sorption (basically, it binds to other molecules in the soil and becomes inactive as a pesticide). When compared with alternative pesticides it is far less dangerous and has very few if any long term effects on soil.
So pretty much no. Actually one of the main reasons it’s so prevalent in spot-treatment at the consumer level is because it has fast, noticeable effects, and then everything goes back to normal quickly.

I’m sure it’s just a misunderstanding but your correction is incorrect. While you are on the right track saying a substance used to kill plants is called an herbicide, an herbicide is a type of pesticide. If you are using an herbicide to kill an unwanted plant, you are practicing pest control with a pesticide.
