Seed treatments induced systemic resistance in chickpea against Fusarium wilt in wilt sick field

摘要

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.
