First report of Limonomyces roseipellis causing pink patch on bermudagrass in South China.
Hybrid bermudagrass (Cynodon dactylon × C. transvaalensis) is widely used on golf course putting greens in southern China. In September 2011, circular pink patches ranging from 10 to 20 cm in diameter were observed on putting greens established with cv. 'Tifgreen' on a golf course in Haikou, Hainan Province. There were approximately 50 pink patches on a putting green. Infected leaves were covered with pink, gelatinous fungal mycelium, which resulted in the production of chlorotic lesions. Lesions expanded, became water-soaked, and leaves died basipetally. Based on morphological characteristics, sequence analysis of the rDNA internal transcribed spacer region and pathogenicity tests, causal agent was identified as L. roseipellis. This is the first report of L. roseipellis causing pink patch on hybrid bermudagrass in China.
