As we get older, these little spots dry out completely, and the blade eventually falls off, revealing a hole. <i><b>Stemphylium solani</b></i> (grey leaf spot)
Slight chlorosis of the limbus at the periphery of the spots. <i><b>Stemphylium solani</b></i> (grey leaf spot)
Some spots can merge, causing very significant damage in the long term. <i> <b> Stemphylium solani </b> </i> (stemphyliosis, gray leaf spot)
