Abstract
Laboratory tests indicated that C. trifolii (Kauff.) Boedijn can cause severe disease of the turfgrasses Agrostis tenuis Sibth., A. palustris Huds. cv. ''Pencross'' and Poa annua L., particularly at 25.degree.-35.degree. C. Festuca rubra L. var. commutata Gaud. was moderately resistant. C. trifolii isolates differed in virulence on these hosts. Optimum temperatures near 30.degree. C for growth in culture were closely related to optimum temperatures for disease development. Turf temperatures in the range most conducive to C. trifolii disease development occur in summer. In vitro fungicide tests showed that mancozeb and thiram were most inhibitory to C. trifolii, although 11 isolates differed in their susceptibility to thiram.This publication has 1 reference indexed in Scilit:
