Initially, symptoms of fusarium wilt appear as one-sided wilting of only half of the plant, branch, or leaflet. At first, the plant will appear to recover from the wilt, but as the disease progresses, it will become permanent regardless of temperature or water status. Lower leaves will become yellow first before chlorosis spreads to the higher branches, eventually leading to defoliation. Plant growth is typically stunted and few to no fruit develop. If the stem is cut open near the base of the plant, longitudinal light brown streaks can be seen within the vascular tissue (center of the inner stem). This discoloration can be slight and difficult to observe.
