Clopyralid

Clopyralid is known as a active ingredient in herbicides that kill selective weeds like clover, thistles, and other hard to kill weeds. Clopyralid belongs to the pyridine family of chemicals. It has a high persistence and stays in compost or dead plants, even up to 14 months.

Mode of Action

As a plant growth hormone (synthetic) it disrupts plant growth by binding molecules that are normally used as receptors for natural growth. This binding causes abnormal growth, killing the plant.
