Abstract
The strobilurin fungicide ;Amistar; active ingredient azoxystrobin provides effective control of a wide range of fungal diseases on many important tropical crops. The exceptional activity of ;Amistar; in controlling a broad spectrum of commercially important pathogens will mean that many growers will use ;Amistar; as their fungicide of choice. In anticipation of this Zeneca has worked with the Fungicide Resistance Action Committee FRAC to establish clear guidelines to minimise the possibility of resistance arising. More than 20 studies have been established to determine baseline sensitivities of key pathogens and programmes of sampling and monitoring are in place throughout the world. This paper describes Zeneca;s approach to baseline sensitivity monitoring with ;Amistar;. We have chosen specific examples which illustrate the principles of such research and show some of the specific points which should be considered when carrying out sensitivity monitoring with strobilurin fungicides. There are cases where fully validated in vitro methods can provide reliable baseline data but in most cases in vivo assays provide a much better picture of the field population sensitivity than in vitro analysis. These data represent only a small subset of the baseline studies currently being carried out by Zeneca worldwide. Proposals for managing resistance are also discussed.
