Summary
Verticillium wilt was confirmed in 56% of 108 tomato fields surveyed (56.5% of 65.6 ha) in western North Carolina in 1976. Estimated disease incidence in the surveyed region was 9.2%. Eighty-nine of 96 Verticillium dahliae isolates recovered from susceptible cultivars in the survey were race I; seven were race 2. Six race 2 isolates came from fields not previously cropped with race I-resistant cultivars. In field tests, mean yields were reduced in susceptible cultivars Manapal and Walter and race I-resistant cultivars Flora-Dade and Monte Carlo, respectively, by as much as 39.9, 47.1,3.5, and 6.5% by race I isolates and 10.3, 31.2, 19.3, and 22.8% by race 2 isolates.
