The symptoms of Fusarium wilt in cucumbers include yellowing and wilting of lower leaves, which progresses upwards until the whole plant is affected. Leaves may appear dull green or yellow, and the plant might exhibit stunted growth. Browning of the vascular tissues in the stem, visible when cut near the base, is a clear sign. Infected cucumbers often produce fewer and smaller fruits. To manage Fusarium wilt, choose resistant varieties and ensure good drainage to prevent the fungus from spreading.
