ARTICLE ANNOTATION

quote
This article provides information on two of the most widespread diseases affecting walnut trees worldwide— Marssonina leaf blotch and bacterial blight. The occurrence and development of these diseases in different walnut cultivars were assessed by examining 100 leaves and 100 petioles per tree. The severity was recorded using standard evaluation scales. Based on these data, the disease index (DI) for each cultivar was calculated. The disease incidence (I) was determined using the standard formula (1).
