Efficacy of chemical inducers against wilt of chickpea incited by Fusarium oxysporum f.sp. ciceri

Abstract

The aim of present study was evaluation of different inducers against Fusarium oxysporum f.sp. ciceri in in-vitro in seven treatments with three replications. Efficacy of different chemical inducers viz. Salicylic acid, Oxalic acid and Ascorbic acid in controlling the growth of Fusarium oxysporum f.sp. ciceri, were used in different concentrations i.e. 100ppm and 200ppm using poisoned food technique. The pathogen was isolated from the disease affected roots of chickpea from the field of Uttaranchal University. The fungal discs of seven days old culture of the pathogen were inoculated in poisoned PDA media. The chemical inducers showed decent effective control in the growth of the pathogen at every observation taken. Salicylic acid at 200ppm showed the highest control on the growth of the pathogen while the lowest was shown by Oxalic acid at 100ppm after 7 days of inoculation. The maximum percent inhibition was done by Salicylic acid at 200ppm whereas, the minimum inhibition was done by Oxalic acid at 100ppm.
