Among the nine treatments tested, Gliocladlum virens inoculum @ 10.0g/pot + neem cake (50g/pot) + FYM (500g/pot) showed maximum reduction in T.paradoxa population (50.6%). Trichoderma harzlanum, T. viride and T. hamatum, showed comparatively lesser reductions in T. paradoxa population. (31.3,25.3 and 21.9% respectively). Neem cake + FYM alone (@ 50g & 500g/pot respectively) showed the feast reduction In T. paradoxa population (6.1%). Among the four antagonistic fungi tested, maximum post-treatment populations were observed with T. harzlanum (334.67 and 406.67x104 cfu/g for the doses of 5 and 10g/pot respectively), followed by the populations of G.virens (66.06 and 82.6 x 104cfu/g for the doses of 5 and 10g/pot respectively). Soils amended with neem cake + FYM showed Increased levels of native populations of G. virens (0.0262 x 104 cfu/g) and 7: harzlanum (3.8187 x 104 cfu/g) compared to their populations in the un-amended soils (0.0029 and 0.0921 x 104 cfu/g respectively).enArticle
