Fusarium wilt—Fusarium oxysporum f. sp.
In areas where disease inoculum is high, seedlings may wilt. However, symptoms generally appear after
fruit is set and consist of yellowing of a runner on one side of the plant followed rapidly by wilting
of the infected runner. Runner lesions develop and extend from the crown to the tips. Other runners collapse
in a similar manner and whole plant collapse occurs rapidly. External lesions may develop on roots accompanied
by red gumming at or just below the soil surface. Internally, a dark red brown vascular discoloration
may extend from roots to runners.
The fungus that causes Fusarium wilt survives in the soil and enters plants through roots. Use clean
tools after working in the garden area so as not to spread the disease. Some varieties may show resistance.
