Russian Thistle Weeds can be very invasive.Russian thistle is a bushy annual forb that many of us know as tumbleweed.Managing tumbleweeds is difficult because the seeds fall off and germinate even the driest of areas.Burning also does not work well for thistle control. Controlling the Russian Thistle can be accomplished through chemicals or by pulling the plants up by their roots before they seed.Some herbicides are effective against Russian Thistles such as 2,4-D, dicamba, or glyphosate. Keeping fields full of healthy crops prevents the establishment of Russian Thistle.
- Mowing the plants when they begin to bloom are a good way to control Russian thistle.
- Uprooting the young plants is a good way to control the spread of Russian thistle.
- Burning the plants does not control Russian thistle very well.
“The best control of Russian thistle does not involve chemicals. It is replanting infested areas with other plants.”
