Abstract
Survival of Bortytis cinerea sclerotia and conidia was favoured by low temperatures. Germinability was lost rapidly at 30° C. B. cinerea sclerotia held in dry storage at temperatures of 5-20° C remained at least 25% viable after 90 days. Sclerotia held at 25° Clost germinability after 60 days and sclerotia held at 30° Clost germinability after 30 days. Sclerotia held in moist nonsterile soil lost viability within one month at temperatures above 5° C. Sclerotia left 2.5 cm below the soil surface in a coffee plantation at high altitude,also decayed after one month. Sclerotia which had been held at low temperatures (5-15°C), on germination, produced profuse conidiophores and conidia.
