%X The effects of environmental factors on components of the life cycle of Puccinia menthae on Mentha &#215;  piperita cv. Tod&#8217;s Mitcham were examined. Urediniospore germination required at least 6 h leaf wetness and lasted 4-6 h at temperatures of 5-25&ordm;C. Appressoria, substomatal vesicles, and haustoria were produced 6, 6, and 24 h after inoculation, respectively, at 20&ordm;C. The latent period of infection ranged from 50 days at 5&ordm;C to 10 days at 22&ordm;C. Sporulation occurred over a wide range of temperatures (5-27&ordm;C), the optimum being 15-20&ordm;C. The minimum, optimum, and maximum temperatures for infection were &#60;5, 20, and 27&ordm;C, respectively. Teliospore formation required a minimum of 9 days of cold treatment (4&ordm;C) and the ratio of teliospores to urediniospores produced was inversely proportional to the duration and intensity of light received.
