Plant disease reference
Catalogue of crop diseases: fungal, bacterial, viral diseases and nematodes. For each disease — the pathogen, typical symptoms, affected crops, effective control and prevention measures.
Diseases are linked to the catalogue: a disease page lists resistant varieties, and a variety's specs show its resistance to specific diseases. Use the filter on the left to select diseases by pathogen type or affected crop.
