To identify the meteorological factors which favour the development of stripe rust disease in wheat correlation and regression analysis was carried out by using 7 years (2004-11) data. In order to evaluate the reasons for the same an effort has been made to short list the weather parameters responsible for this wide variation in the occurrence of the disease. The maximum temperature for 48th and 49thstandard meteorological weeks (SMW) were positively correlated while sunshine duration for 49th to 50th SMWs were negatively related. On the other hand, minimum temperature, rainfall and RH during 2nd and 3rd SMWs were positively corelated with the disease intensity. As such the disease will be higher in those years, when temperature will be higher than normal coupled with high relative humidity during December and January.
