Fusarium wilt on asparagus—Fusarium oxysporum f. sp. asparagi
Mature plants infected with Fusarium gradually decline in productivity and growth. Spears are
weak and spindly. A reddish brown vascular discoloration, which may extend into the crown, is present
at the base of infected stalks. Crowns and belowground portions of stems exhibit reddish flecks or sunken
brown lesions, which can be seen when the plant is cut open.
Fusarium wilt is introduced on transplants. Once in the soil, little can be done to prevent it from infecting
other plants. Plant resistant varieties. If direct seeding, use clean seed.
