Abstract: Induced systemic resistance in chickpea against wilt disease caused by Fusarium oxysorum f. sp. ciceri (FOC) was studied by treating the seeds with benzo (1,2,3)-thiadizole-7-carbothioic acid -s- methyl ester (Bion), salicylic acid (SA) and di- potassium hydrogen phosphate (K₂HPO₄). Reduction in disease was observed in both type of applications but seed dressing was found more effective than soaking method. Highest reduction, 63% in wilt disease was observed with Bion dressing followed by SA, 40% and K₂HPO₄ , 30%. Bion and SA showed 41 & 24% reduction in the disease, respectively, when seeds were soaked in the respective chemicals but no reduction was found with K₂HPO₄ soaking. Slight increase in yield was observed with all the treatments in both applications but difference among them was statistically non-significant.
