The emergence of fungicide resistance is a major challenge facing agriculture. With increasing regulation and costs limiting the development of new fungicides, farmers remain reliant on a relatively small group of working fungicides, many of which are decreasingly effective as major crop disease pathogens develop resistance to them. Understanding and minimising fungicide resistance provides an authoritative review on the wealth of research on understanding the development of fungicide resistance in agricultural crops and the establishment of preventative measures which can be implemented to limit its spread and the consequent impact of disease on yields. This collection includes ways of understanding and preventing resistance to key groups of fungicides, such as SBI, Qol, SDHI and OSPBI.
