Abstract

Mineral nutrition affects a plant's susceptibility to plant diseases, especially when the element is deficient or the plant is under environmental stress. Both macro- and micronutrients as well as beneficial elements affect plant health via numerous mechanisms, such as activating enzymes that produce defense metabolites, for example, lignin and phytoalexins, and indirectly by altering the root exudates, rhizosphere pH, and microbial activity. The role that each nutrient plays in plant disease suppression must be viewed holistically due to the numerous interactions with other elements, the host plant, rooting medium, and with beneficial and pathogenic microorganisms.
