The symptoms on the above-ground parts of the plant generally do not begin to show until late spring and early summer. Overall, the plant ceases to grow, or is stunted in growth, and shows a decline in runner development. The younger plant leaves turn blue-green, and older leaves turn red or yellow. The plant will wilt and collapse. In some cases, not frequently, the plant will merely wilt and die before visible symptoms are able to develop above the ground. The plant may die before fruiting, but if there is fruit produced it will likely be small, deformed, or dry.
