Valsa canker, caused by the fungus Valsamali, is one of the most destructive diseases of apple in the primary production areas of China.Currently there are no effective control methods for this disease.We investigated the occurrence of Valsa canker in apple orchards in Shaanxi Province in concert with foliar nutrient analysis, and found that there was a significant negative correlation of leaf potassium (K) content with incidence and severity of Valsa canker.
