  • Coumatetralyl is an anticoagulant of the warfarin type.
  • Coumatetralyl technical is a white to yellow-grey crystalline powder with a characteristic slight odour and a melting point of 168.8C.
  • It is not highly flammable and does not liberate gases in hazardous amount upon contact with water or undergo spontaneous combustion.
  • Coumatetralyl is commonly used with grains and other cereals as a rodent poison in conjunction with a tracking powder to monitor feeding activity in a particular area.
  • With the increase in population and environmental change, scientists have seen a dramatic increase in pests around the globe.
  • Rodent control is needed to prevent disease transmission, contamination of food and feeding stuffs and structural damage.
  • Coumatetralyl is of very high acute toxicity by the oral route and the inhalation route and of high toxicity by the dermal route.
  • Coumatetralyl is not considered to be genotoxic or carcinogenic or to affect the reproductive capability, although no long term studies were available due to the pharmacological well-known effect of this anticoagulant.
  • Coumatetralyl can be classified as a moderately leachable compound in sand soil. In loamy sand and sandy loam no leaching of coumatetralyl was observed.
  • Anticoagulant rodenticides are easily absorbed from the gastrointestinal tract, and may also be absorbed through the skin and respiratory system.
  • The major difference between warfarin and the other anticoagulants (both indandiones and second-generation hydroxycoumarins) is that they have
    a longer retention time in the body and consequently a more prolonged effect than warfarin.
  • The major difference between first- and second-generation anticoagulant rodenticides is that the latter have longer body retention and therefore
    tend to lead to a longer period of bleeding.
  • Anticoagulant rodenticides are available in a variety of different formulations, including paraffin wax blocks, whole grain baits, pelleted baits and tracking powder
