Is Chlorsulfuron effective against field horsetail and scouring rush?

Chlorsulfuron is a systemic herbicide belonging to the sulfonylurea family, which is known for effectively controlling a wide range of broadleaf weeds and some grass species. However, it's important to note that while chlorsulfuron has strong performance against many annual and perennial weeds, it is not considered effective against all plant species.

Field horsetail (Equisetum arvense) and scouring rush (Equisetum hyemale) are both members of the Equisetaceae family and are known for their resilience and ability to thrive in various conditions. In fact, horsetails are considered difficult to manage with many conventional herbicides, including chlorsulfuron. This is primarily due to their unique biology, which includes a deep rhizome system and the production of spores instead of seeds, making them less susceptible to chemical control methods that target seed germination or root systems of typical broadleaf weeds.

Thus, stating that chlorsulfuron is effective against these specific plants is not accurate, and the notion that the herbicide can control them does not hold up against practical application results. In conclusion, the assertion that chlorsulfuron is effective against field horsetail and scouring rush is incorrect
