The current threat of ash dieback and the devastation to the countryside caused by Dutch elm disease in the 1960's and 70's will be familiar to many. Other less well known diseases continue to threaten crops in the developed and developing countries. From ash dieback to cassava diseases in Africa and global threats to wheat, this lecture will examine disease spread and control strategies.
