| DOT-Kennzeichnung | Poison |
| Brandgefahren | May release nitrogen oxides. Containers may explode in heat of fire. Avoid alkalies. Stable under neutral or acid conditions. (EPA, 1998)Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion if formulations contain flammable/explosive solvents. |
| Gesundheitsgefahren | This material is extremely poisonous. May be fatal if swallowed, inhaled, or absorbed through skin. Contact may burn skin or eyes. Probable lethal oral dose to humans 5 to 50 mg/kg or 7 drops to 1 teaspoon for 150 lb. person. (EPA, 1998) |
| Gefahrenübersicht | Classified as highly toxic or moderately toxic depending on the formulation, it may be used only by certified applicators. [EXTOXNET] Allergic contact dermatitis in pesticide handlers is most likely due to maneb, carbofuran, carbaryl, captan, folpet, or captafol. [Marks, p. 312] See CARBAMATE INSECTICIDES. |
Anwendungen & Verwendung
Beschreibung
Carbofuran is another systemic insecticidal/nematicidal carbamate available in granular and liquid formulations. Because use of carbofuran granules was associated with bird kills, the U.S. Environmental Protection Agency (EPA) prohibited the use of carbofuran granules in 1994.
Verwenden
Carbofuran is used to control soil-dwelling insect pests and nematodes in a wide range of crops.
