STRATEGIES FOR THE PREVENTION OF DEVELOPMENT OF PESTICIDE RESISTANCE IN THE UK - LESSONS FOR AND FROM THE USE OF HERBICIDES, FUNGICIDES ANDINSECTICIDES

Since the 1950s, pesticide resistance has been identified in many spec ies. This paper considers the role of resistance action groups and not es that they were all formed in response to resistance problems occurr ing. Data now exist on the strategies which are most effective and the paper aims to bring together information from the fields of weeds, pe sts and diseases. Pesticide mixtures, sequences or rotations have been demonstrated as having a dear role in resistance management strategie s. Resistance management would be improved if there was agreement on u niform test methodology and interpretation of results. The industry mu st work together to agree what constitutes an anti-resistance strategy , whether this is for prevention or cure, and to ensure that this is t hen included within regulatory frameworks. Future developments such as patch treatment, biotechnology and biocontrol are discussed. It is co ncluded that, to date, there has been little discussion between specia lists in the field of resistance to herbicides, fungicides or insectic ides and it is clear there are significant advantages to be had from m ore interaction.
