Fusarium Wilt

Fusarium oxysporum

A soilborne fungal disease affecting a wide range of tree species, causing vascular wilt through vessel plugging. The pathogen survives long periods in soil through specialized resting spores and typically causes death within 18 months of infection onset.

Peak Season: Infection: Year-round through root woundsSpore germination: With increased moisture and temperatureSymptom development: Progressive throughout growing seasonPeak activity: During warm, moist conditionsSurvival: Long-term through chlamydospores in soil

Fusarium wilt symptoms

Identification & Symptoms

What to Look For

Wilting or yellowing of leaves, first on scattered top branches
Leaves hanging down before dying and dropping
Red to brown ring of discolored sapwood in trunk and branches
Xylem plugged with brown gum
One-sided wilting of small branches
Bark flattening over collapsing tissue
Shepherd's crook appearance from inward turning branches

Potential Damage

Progressive vascular system disruption
Tree death typically within 18 months
Complete vessel plugging preventing water transport
Branch mortality from gum occlusion
Structural collapse of affected tissues
Economic losses in susceptible plantings

Lifecycle

Completely soilborne pathogen spreading through hyphal growth or spore germination. Microconidia and macroconidia serve as primary inoculum. Specialized chlamydospores enable survival during unfavorable conditions. Germination occurs with proper host presence, adequate moisture, and higher temperatures.
