Abstract/Contents:"Red thread and pink patch, caused by the fungi Laetisaria fuciformis and Limonomyces roseipellis, respectively, are important diseases of many turfgrass species worldwide. In this study, we analyzed the biological characteristics of these two pathogens and evaluated their responses to 14 different fungicides. The results showed that L. fuciformis and Li. roseipellis grew well at pHs ranging from 5 to 7, and the optimal pH value was 6. The hyphae of both pathogens lost viability in agar plugs that were incubated at 50° for 10 min. The optimal carbon and nitrogen sources for L. fuciformis and Li. roseipellis were soluble starch and L-glutamine, respectively. The optimal medium for L. fuciformis was oatmeal agar (OMA) and that for Li. roseipellis was potato dextrose agar (PDA) or potato sucrose agar (PSA). Among the 14 fungicides, diniconazole had the strongest inhibitory effects on L. fuciformis and Li. roseipellis with EC50 values of 0.113 mg/L and 0.282 mg/L, respectively. The fungicide with the weakest inhibitory effects was 15% metalaxyl·10% propamocarb, with EC50 values of 121.522 and 214.532 mg/L for L. fuciformis and Li. roseipellis, respectively. The results provide a scientific basis for understanding the basic biology of these pathogens, and may be useful for the development of new management strategies."
