Info

Soil Borne Pathogens • Symptoms are not diagnostic – not even to separate biotic from abiotic • There is no one single method for isolating or identifying all root or crown pathogens • All cause “browning”, streaking <strong>and</strong> decay • Field guides offer only clues: more red- than brown, more orange- than red, buff-colored, tan-colored, reddish- colored, rust-colored, cinnamon-red or chocolate- brown, brown- but not black ??
Soil Borne Pathogens • Microscopy alone not usually an option • For regulatory purposes, identification needs to be at least to species, often to a subspecies or variety level (highly accurate) • Without selective isolation techniques, pathogens cannot be detected or confirmed • Saprophytic competitors <strong>and</strong> secondary pathogens quickly invade diseased tissues making diagnosis impossible
