Pennsylvania Smartweed
The key to Smartweed control is treating early before the weeds become too well established. GrazonNext HL or Grazon P+D are effective on this weeds less than 12 inches tall. As the weeds get older, the percent of control declines. Chaparral at 2.5 ounces per acre is also effective.
