| Abstract/Contents: | "Anthracnose, caused by Colletotrichum graminicola (Ces.) Wils., was a problem on a bentgrass/annual bluegrass putting green at a country club in Cincinnati, OH, during the summer of 1987. Isolates of C. graminicola collected from the site were tolerant to benomyl in vitro. After 3 days at 27 C, radial growths of tolerant isolates (average of three isolates) on potato-dextrose agar amended with 0, 1, 10, 100, 500, and 1,000 mg a.i. of benomyl (Tersan 1991 50WP) per liter were 18.4, 19.7, 17.8, 13.1, 9.4, and 3.6 mm, respectively; those of sensitive isolates (average of two isolates) were 16.2, 2.9, 2.8, 2.0, 0.5, and 0.0 mm, respectively. Benzimidazole fungicides has been used routinely for at least 5 yr at the site where the tolerant isolates were found. Benzimidazole fungicides have been recommended, labeled, and, in many states, routinely used for control of anthracnose on turfgrass. This report serves as a warning that tolerance of C. graminicola to benzimidazole fungicides can be a significant problem facing turfgrass managers." |
