John Kempf’s plant health pyramid

Level 1 – Plants are able to create carbohydrates and transfer them to the root zone as root exudates.  This provides resistance to soil-borne pathogens such as fungal diseases like fusarium or verticillium.

Level 2 – Plants are able to form complete proteins.  This provides resistance to sucking and chewing insects.  Foliar sprays of Mg, S, Mo, B and molasses are helpful for control.

(Levels 1 and 2 are a function of balanced chemistry in the plant.

Level 3 – Plants are able to form high levels of lipids (fats).  Their leaves are shiny and they have a glow.  At this point they are resistant to airborne pathogens such as powdery mildew.

Level 4 – Plants are producing plant secondary metabolites (PSMs).  At this point plants are resistant to beetle attacks such as from Japanese beetles.
