What does fusarium wilt look like on strawberry?

Wilting and stunting Death of older leaves first Internal browning of the crown Discolouration of the xylem

Fungal disease

Fusarium wilt

Fusarium oxysporum f.sp. fragariae

Soil-borne wilt. Symptoms overlap heavily with Phytophthora crown rot, and the two get confused constantly.

Warm soils, and ground carrying the pathogen from previous plantings.

Plant loss, and a soil problem that persists rather than a season that goes wrong once.

Distinguish it from Phytophthora crown rot before acting — Phytophthora gives a deep red spongy crown, Fusarium a browner internal discolouration with xylem staining
Clean planting material, and rotation away from infested ground
Resistant cultivars where they are available to you

Spray strategy. There is no spray answer to a soil-borne wilt. Control is planting material, rotation and cultivar choice.
