How to get rid of:
Plant-killing chemicals, or herbicides, are one of the best weapons , because they can kill leaves, stems and roots when applied properly. They're especially helpful when you're faced with a large weedy area. In many cases, you'll achieve best success when you combine herbicides with other weed control methods.
Timing is key when applying herbicides; follow label instructions carefully. Most brush killer herbicides also kill desirable plants, so protect existing vegetation when spraying.
