Triclopyr is a selective herbicide primarily used to control woody plants and broadleaf weeds. It works by disrupting the plant's growth hormones, leading to the death of unwanted vegetation. Triclopyr is commonly applied in forestry, rights-of-way, and natural areas to manage invasive species and promote the growth of desirable plants. This chemical is available in various formulations, including liquid and granular forms, and can be applied through spraying or soil treatment. While effective, triclopyr should be used carefully to minimize impact on non-target plants and the surrounding environment.
