| Abstract/Contents: | "Disease of complex etiology have been found on golfgreens of manila grass (Zoysia matrella) during spring season in the southern part of Japan. One determinant of the diseases is identified to be binucleate Rhizoctonia spp.. It has also been known that some other determinants might be involved because, in some cases, the disease cannot be controlled by the above chemicals. The present study was undertaken to elucidate the determinants of such disease. The results obtained are summarized as follows : (1) pythium graminicola, P. torulosum and P. Vanterpoolii were isolated in early spring. Fusarium spp. were also isolated frequently in late fall. (2) Inoculation tests using seedlings of Zoysia japonica revealed that fungal species pathogenic at 10°C and 15°C were identified as Fusarium roseum LK. F. sp. cerealis 'Acuminatum' and as F. nivale. Both Pythium graminicola and P. Vanterpoolii were also highly pathogenic at 15°C. (3) Combined application og benomyl (BE) in fall with metalaxy-hydoroxyisoxazole mixture (MH) in the following spring was remarkably effective to prevent symptom development on Zoysia turf in the fields. Application of MH alone in both seasons was less effective. Application of BE in fall was occasionally effective. We conclude from the above finding that the disease is complex etiologically and manila grass is infected with F. roseum LK f. sp. cerealis 'Acuminatum' and F. nivale in fall and with P. Graminicola and P. Vanterpoolii in the following spring." |
