Contact herbicides are chemicals designed to kill weeds upon direct contact. They work by damaging the plant tissues they touch, leading to the death of the targeted weeds. Unlike systemic herbicides, which are absorbed and transported throughout the plant, contact herbicides typically require thorough coverage of the plant surfaces for effective control. These herbicides are often used for quick action in managing annual weeds and can be effective in non-crop areas.
