Title: Resistance risk assessment within herbicide authorisation - a call for sensitivity data

Abstract: In most European countries, the risk of herbicide resistance is assessed as part of the authorisation of herbicides in accordance to the EPPO Standard PP1/213. Because the susceptibility of weed populations to a certain herbicide may vary greatly, one part of resistance risk assessment is the testing for sensitivity variation among different population of target weed species with a high resistance risk. This paper emphasizes the importance of sensitivity data provision with regard to the recent Regulation (EC) 1107/2009 concerning the placing of plant protection products on the market and outlines the main technical requirements for sensitivity data. Useful principles include that sensitivity data should be provided for all herbicides with a high resistance risk regardless of whether resistance has already evolved against the herbicidal substance. Methodical details regarding the generation of sensitivity data are discussed, together with remaining questions that will need to be addressed in achieving a harmonised assessment of herbicide resistance risk.
