It’s a disease that affects mostly tomatoes, more commonly known as tomato powdery mildew. It has only recently been identified as a separate species. And it is the 1000th disease to be mapped by CABI, a fact we noted from CABI’s blog.
Distribution Maps of Plant Diseases is a series that has been going since 1942. To view the maps you need to subscribe, although CABI has generously made map no. 1000 available free1. There’s also a collection of Distribution Maps of Plant Pests. Apparently, many of the maps have been drawn up more than once. What I’d really like to see would be time series animations showing how pests and diseases have moved around the world in recent years, what with climate change, air travel and a host of other contributory factors. How about it CABI?
