Episode 181: Plant Immunity Through Custom Foliars and Targeted Nutrition with Peter Henry
Nutrition-first strategy cuts chemical dependence
High disease pressure in tropical fruiting crops is treated as a nutrition-and-biology problem: soil testing, targeted minerals, foliar/soil biology inputs, and variety selection reduce chemical “chasing.”
Fixing minerals changes pest outcomes fast
He reports quick rebounds from low-rate foliar nutrition (e.g., copper/moly/bio-stimulants) that immediately suppress pests like aphids/whiteflies, implying some infestations are downstream of nutrient-stressed plant physiology.
Soil heterogeneity creates different disease systems
Opposite sides of his river show major mineral differences (high manganese/iron vs lower; near-zero molybdenum; varying sulfur), and disease tracks those profiles—so crop management must be sector-specific, not one program farmwide.
