Studies were conducted to test the efficacy of different non-conventional chemicals against Colletotrichum capsici under in vitro and screen house conditions at Department of Plant Pathology, CCS Haryana Agricultural University, Hisar. Inhibition of spore germination inhibition method was followed for in vitro assay while foliar spray on red fruits of chilli followed by pathogen inoculation by pin prick method was adopted for assessing efficacy under screen house conditions. The pathogen, C. capsici was found most sensitive to salicylic acid among different non-conventional chemicals tested under in vitro conditions while under screen house conditions, salicylic acid at the concentration of 5mM induced resistance in plants and gave 67.86 and 78.63 per cent disease control in susceptible (Pusa jwala) and resistant (Pusa Sadabahar) variety, respectively over check.
