Promotion of pine seedling resistance to phoma blight due to fertilizer applications

The results of studies on increasing the resistance of pine seedlings to phomosis by applying fertilizers are presented. It was revealed that foliar top dressing reduces the prevalence and degree of the disease, which is reflected in the improvement of the biometric parameters of seedlings (average height of the aboveground part, length of needles, etc.) in forest nurseries. It has been established that with foliar top dressing of plants the greatest effect in increasing resistance to phomosis is achieved through the use of fertilizers with a high proportion of nitrogen content.
