How do I control johnsongrass (Sorghum halepense) in a home lawn in Frederick County Virginia?
Recommendation: Repeated mowing will eventually kill johnsongrass. Brushing or wicking the foliage of taller johnsongrass with glyphosate is one option. Ingredients in weed killers at your local hardware store that kill johnsongrass include: fenoxaprop, fluazifop, clethodim, sethoxydim, and MSMA. These products will probably need to be applied several times to achieve complete kill of mature plants. Always read and follow label instructions when using pesticides.
