Abstract: Late blight caused by Phytophthora infestans (Mont.) de-Bary is the most important and destructive disease of potato causes “Irish Famine” in 1845. The management of the disease is mainly based on cultivation of resistant variety and use of fungicides. However, resistance against pathogen is not a permanent solution and fungicidal is not eco-friendly and economical. Therefore, inquest for IDM modules by using soil application with compost, tuber treatment with T. harzianum and foliar spray with fungicides were assessed during the course of present investigation. The co-relation between disease severity with rainfall, maximum temperature, minimum temperature and relative humidity showed that disease severity co-relate negatively with maximum temperature and Relative humidity, representing the value (-0.9693) and (0.5731) during 2016-17 and (-0.9521) and (-0.7454) during 2017-18, respectively, but positively co-relate with rainfall and minimum temperature (0.5884) and (0.9954) respectively.
