An experiment was conducted to evaluate calcium chloride (CaCl2) as inducers in induce resistance against late blight of potato caused by Phytophthora infestans. Two per cent CaCl2 used in 9 treatments for different time durations (1/2h, 1h, 2h, 4h, 6h, 8h, 10h, 12h and 0h) and foliar spray and resulted that CaCl2 have ability to reduce disease severity from 22.65 to 48.00 per cent against 57.00 per cent in case of control. Biomolecules changes due to effect of CaCl2 revealed that increase content of soluble protein and total phenol content with the minimum in T8 treatment representing 32.5, 34.5, 34.5, 34.5, 33.1 mg/g fresh leaf of soluble protein, and 2.57, 2.62, 2.74, 2.87 and 2.78 mg/g fresh leaf of total phenol at 2, 4, 6, 8 and 10 days of pathogen inoculation. The correlation coefficient between disease severity with total soluble protein and total phenol content showed negative correlation in both cases.
