The article discusses the problem of horseweed resistant species. Horseweeds have become resistant to glyphosate herbicides. It has been recommended that a tank-mix of glycophosate and dicamba is effective on horseweed. But this has also proved ineffective in some cases due to bad timing of rains and planting of crops. Some farmers are using conventional tillage to kill horseweed. Some of the herbicides and tank mixes recommended by scientist Larry Steckel are glufosinate or Ignite, Gramoxone Max and combinations of residual herbicides.
