The relation between soil moisture content (SMC) and development of phytophthora blight disease of pigeonpea was determined. Among all the SMC, flooding condition yielded the highest occurrence of disease with shortest incubation period (IP). Further assay to ascertain the duration of flooding and disease progress, result shows minimum of 24 hours of flooding is sufficient to initiate the disease with IP period of 24 hours. Among the soil type, black clay soil has produced the high disease incidence compare to red loamy soil. Further, an interaction of different level of inoculums density (1×10-1 to 1×10-6) and soil moisture content shows, even low level of inoculum density is sufficient to cause infection in the host plants under flooded condition, whereas high level of inoculum density and lengthiest IP period is required to cause infection in the host in field capacity of the soil. The study helps in understand the biology of Phytophtohra cajani in relation to soil moisture content and ultimately developing appropriate cultural strategies for management of disease efficiently.
