Efficacy of Bioagent and Different Root Extracts for Suppression of Chickpea Wilt In Vitro

In an attempt to study the effect of different ischolar_main extract and bioagent against Fusarium oxysporum f.sp.ciceri in laboratory, least radial mycelial growth and maximum inhibition was recorded in sorghum ischolar_main extract medium (28.00 mm and 54.34%), respectively, however, it was at par with groundnut ischolar_main extract medium (30.00 mm and 51.08%) as compared to control (61.33 mm). In dual culture technique the growth of Fusarium oxysporum f.sp.ciceri was restricted by Trichoderma viride (56.16%) followed by Trichoderma harzianum (50.57%). Trichoderma lignorum gave minimum zone of inhibition (40.45%).
