A yellow leaf disease of Zoysia materella (L.) Merr, and Zoysia japonica Steud. is recognized on the golf course at spring and early summer in Japan.
Electron microscopic examinations of ultra-thin sections of yellow leaf disease of Zoysia materella (L.) Merr. showed none of the Mycoplasma-like organisms in the phloem cells of the diseased leaves.
The disease was not recovered after the treatment of oxytetracycline (HCI and base) in Knop's solution and spraying at the concentrations of 500 and 1, 000 ppm.
Inoculation tests to Zoysia materella (L.) Merr. by Fusarium sp. which was isolated from the yellow leaf disease did not succeeded.
Dithane and Carbamysol did not cured the disease when sprayed on the leaves in the turf.
