Systemic herbicides are chemicals designed to kill unwanted plants by being absorbed through their leaves, stems, or roots. Once absorbed, these herbicides travel throughout the plant's system, disrupting essential processes like photosynthesis and nutrient transport. This makes them effective against a wide range of weeds and invasive species. These herbicides are often used in agriculture and landscaping to manage weed populations. Common examples include glyphosate and triclopyr, which target specific types of plants while minimizing damage to surrounding crops. Proper application and safety measures are essential to prevent harm to desirable plants and the environment.
