Abstract
The investigations were undertaken to know the effect of environmental factors on development of Alternaria leaf spot of isabgol (Plantago ovata Forssk.) caused by Alternaria alternata which has become an severe problem in Isabgol growing areas of Rajasthan. Maximum increase in disease intensity (11.20-14.60%) was recorded from the third week of January, 2017 which was due to occurrence of rainfall. with high humidity (89%) and maximum temperature of 24.7 0C. Rate of disease progress was positive correlated with rainfall and relative humidity.
