Vapam HL is a restricted-use soil fumigant containing 42.0% Metam ithiodicarbamate. It is designed for use on specific crops to control a wide range of soil-borne pests, including various weeds, diseases (such as Rhizoctonia, Pythium, and Phytophthora), nematodes, and symphylds. The product is applied via water-run applications, such as chemigation or soil bedding equipment. Because it is highly toxic, it must only be used by certified applicators under their direct supervision. Handling requires significant personal protective equipment (PPE), including chemical-resistant clothing, gloves, footwear, and respiratory protection (such as a NIOSH-certified air-purifying respirator) depending on the application method. The label emphasizes strict adherence to buffer zones, entry restrictions, and environmental safety to prevent contamination of water and non-target areas. It is highly toxic if absorbed through the skin and can cause severe eye damage.
