Overall this book is well written. It gives an up-to-date view on factors affecting pesticide usage, restrictions, the need for IPM (integrated pest management) and the role of biopesticides within an IPM framework. Chapter 1 is a good introduction, covering complex regulatory barriers, innovations and inter-disciplinary challenges for biopesticides, including food security, global food demand and climate change. Chapter 2 covers the main types of pests, pathogens and weeds attacking global crops. It also introduces problems of pesticide over-usage, including pesticide resistance, pest resurgences, secondary pests, loss of biocontrol agents, environmental damage and consumer exposure via food residues. Chapter 3 covers biopesticide types and product numbers, mainly in the EU and USA. It also gives useful information on the use of biopesticides and biocontrol agents for IPM. The regulation of biopesticides is discussed using a useful table. Chapter 4 covers the costs and benefits of switching crop protection technologies, alongside agri-environmental policies, using the UK as an example of the approaches already being used. Chapter 5 tackles complex international regulatory issues. It is quite technical and detailed, so is of most benefit to specialist readers. The loss of conventional products due to EU 91/414 highlights the need for new solutions but indicates that the route to substitutive solutions is slow and complex. Chapters 6 and 7 expand on the steps involved in biopesticide regulation and have an interesting discussion on the role of consumers and other socio-economic factors. The book concludes that there are no silver bullets and that collaborative, multi-disciplinary research between economists, political scientists and biologists is urgently needed. Definitely worth reading if you are interested in future crop protection issues.
