Abstract

A pigeon pea plot at the ICRISAT Centre, Patancheru, India, was observed daily during the 1987 and 1988 rainy seasons for blight infection (caused by P. drechsleri f.sp. cajani). Disease onset occurred on Jul. 10 and on Aug. 4 in 1987 and 1988, respectively. In both years, infection and subsequent disease development occurred when day temp. were <28°C. Rain was recorded on 7 consecutive days prior to disease onset in 1987 and on 5 of 7 days in 1988. An increase in soil inoculum levels was also associated with a decrease in day temp., higher rainfall and cloudy weather
