Nutrients like Phosphorus, Potassium, Manganese, Zinc, Boron and Silicon have been proven by research to boost plant immunity.  Similarly Salicylic Acid and Jasmonic Acid play an active role in defending the plant against pathogens.

Phosphorus is responsible for root development, a healthy root system can not only fight successfully against root rot and other soil borne pathogens, but also improve plant immunity by ensuring a balanced supply of nutrients to the plant.  Potassium and Boron strengthen the cell wall and cell structure which prevents fungi and other pathogens from entering the cell. Manganese blocks the formation of enzymes like aminopeptidase, that aid in fungal growth inside the cell.  Role of Silicon is also important in strengthening the cell wall and helping the cell ward off harmful pests and diseases.

Along with the nutrients, enzymes like Salicylic Acid and JAsmonic Acid play an important role in fighting pathogen infestation. 

Therefore, a balanced supply of Phosphorus, Potassium, Manganese, Zinc, and Boron is essential for improving the disease resistance of crops.  Use of biostimulants that activate the Salicylic Acid and Jasmonic Acid pathways further boost the plant defenses against pathogens.
