The effect of various conditions on survival of Sclerotia and Conidia of Botrytis cinerea F. sp. coffeae, the cause of warty disease on coffee in Kenya
Survival of Botrytis cinerea sclerotia and conidia was favoured by low temperatures. Germinability was lost rapidly at 30ðC. B. cinerea sclerotia held in dry storage at temperatures of 5-20ðC remained at least 25 viable after 90 days. Sclerotia held at 25ðC lost germinability after 60 days and sclerotia held at 30ðC lost germinability after 30 days. Sclerotia held in moist nonsterile soil lost viability within one month at temperatures above 5ðC. 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 (5-15ðC), on germination, produced profuse conidiophores and conidia
