Studies were conducted in 1984 at Kampaengsen campus, Kasetsart University, to examine the role of environmental factors (rainfall, humidity, soil and air temperature) on the development of black spot and rust diseases of peanut. Disease incidences were determined every 7 days throughout the crop duration (May-August 1984). The incidences of both diseases were low up to mid-July, and this could be largely accounted for by fluctuations in environmental factors. Rainfalls in mid-July and early August created suitable conditions for the development of both diseases, and the disease incidences increased up to 6 scale. The suitable conditions for disease development were average air temperature of 28-30 deg. celsius and stable relative humidity at 70-80 %. However, low soil temperature after the second rainfall (Aug 6) might suppress the activity of soil borne inoculum of C. personatum. Latent periods of black spot and rust were found to be 2-4 weeks and 5-6 days, respectively.
