【 摘 要 】

Aspects of the biology and control of Pestalotiopsis on hardy ornamental nursery stock (HONS) were studied. The species of Pestalotiopsis most commonly found on samples of diseased HONS collected from nurseries throughout the UK was identified as Pestalotiopsis sydowiana (Bresad.) B. Sutton. The colony morphologies, spore measurements and hyphal extension rates of all isolates of P. sydowiana collected were similar. Different isolates of P. sydowiana were able to grow well on commonly used agar culture media, including SDA, V8, MEA, CDA and PDA. Optimum temperatures for growth of several isolates were in the range of 15 to 25
