Cultural Method Is Possible in Giant Noxious Weed Control

If you are willing to be persistent, cultural control is possible. You can use black plastic to cover the full infestation, allowing only a little growth at the bottom. While the persistence is a downside, another is that some of the plant will survive. It will drop its black seeds and will allow more plants to grow in the future. You will need to mix cultural control with herbicide treatments. This will remove the seeds and prevent the growth of the plant. When the seeds start to sprout, you will need to pull the plants by hand.

What About Biological or Mechanical?

There are currently no known biological agents that help to suppress the growth of any type of knotweed. As for mechanical options, they are not recommended. They only way to get rid of this noxious weed is by pulling it completely out by the root system. This is complex and it’s easy for seeds to drop. If you do decide to use mechanical treatments, make sure all parts of the plants are bagged or fully burned.
