Pre-foliar spray with indole acetic acid, metalaxyl, dipotassium hydrogen orthophosphate, hydrogen peroxide, calcium chloride, salicylic acid and ferric chloride as inducers provided induced resistance in plant against F. o. f.sp. lycopersici, resulting in a decline in the disease incidence from 90.96 to 9.30% after 15 days of pathogen inoculation. The minimum disease incidence (9.30%) was reported from calcium chloride treated plants. Challenge inoculation with abiotic inducers sensitized the seedling to produce increased level of soluble protein. The maximum increase of soluble protein content was found in calcium chloride treated plant showing 35.93, 36.27 and 35.22 mg/g of fresh leaves at 5, 10 and 15 days of pathogen inoculation. Similarly, phenol content was also found to be maximum in calcium chloride treated plant, representing 2.45, 2.76 and 2.67 mg/g of fresh leaves at 5, 10.. View More»
