In most cases yes. I usually always use something in my pre-emergent tank to kill adult weeds. Be careful though, spraying preemergent around most shrubs and trees will not harm them, but spraying Eraser will - it's the same thing as Round UP. You can kill trees and shrubs with Glyphosate. Just be careful and know what you are doing.
