Occurrence and avoidance of fungicide resistance in cereal diseases
About This Book
The targeted use of fungicides can help minimise the yield losses caused to grain cereals by plant pathogenic fungi. However, the long-term use of fungicide classes based on a single mode of action has imposed consistent selection pressures on certain pathogens. Over time, this has resulted in many cases of fungicide resistance, leading to a reduction or the total loss of field performance of a range of active ingredients. There is a pressing need to develop anti-resistance management strategies. This chapter briefly reviews the development of resistance in cereal pathogens, before presenting and evaluating a variety of anti-resistance strategies. We include case studies of how data from field trials have helped to illustrate the impact of different control strategies.
