Pest identification and confirmation—Fusarium and Verticillium wilt
Both Fusarium and Verticillium wilt cause leaf yellowing and discoloration of the water-conducting tissues
of the plant. Cut affected plants at the base of stems and examine them in cross section to see the browning
of the water-conducting tissue compared to the healthy ivory of uninfected plants. Verticillium
and Fusarium discoloration are extremely difficult to distinguish, although Fusarium discoloration
tends to be darker. Fusarium tends to occur more in warmer soils and Verticillium in cooler
ones. Management for both requires resistant varieties.
