Retrieving and retaining older and advancing novel rodenticides-as alternatives to anticoagulants

Anticoagulant compounds are likely to play an important role in the control of commensal rodents for crop protection and conservation for the foreseeable future. However there are concerns regarding their persistence and the development of more widespread resistance. We are seeking to retrieve and retain older alternatives and develop novel rodenticides. Our three pronged approach is firstly to improve the performance of older non-anticoagulant rodenticides such as zinc phosphide, secondly to optimise the performance of 1st generation anticoagulants and thirdly to identify alternatives to anticoagulant rodenticides with the same mode of action as paraminopropiophenone (PAPP), which was registered in New Zealand as a predacide in April 2011.
