pre emergence herbacide
What is the pre emergent herbacide used around people and animals? I want to prevent weeds and grass growingmin my cyclone fence. Thank you, Kathy Haglund

Thank you for your question, Kathy. I suspect you are referring to trifluralin, the active ingredient in Preen. Here is an article about it and other weed prevention methods: https://hortnews.extension.iastate.edu/1996/5-3-1996/weeds.html Hope this is helpful. Good luck!
