Antagonistic Effect of Fungal Bioagents Against Fusarium oxysporum F.Sp. ciceri in vitro

Chickpea (Cicer arietinum L.) commonly known as gram or Bengal gram, is an important pulse crop and infected by several fungal, bacterial and viral diseases. Among the fungal diseases, fusarial wilt caused by Fusarium oxysporum f.sp. ciceri (Padwick) synd & Hans, is wide spread and a serious threat to chickpeacultivation in Saurashtra region of Gujarat state. Biological control is an important and integral part of integrated plant disease management system, especially against soil borne plant pathogens. All the Trichoderma spp. exhibited high efficacy against Fusarium oxysporum f.sp. ciceri Trichoderma harzianum-II isolate showed maximum growth inhibition (84.76%) andsevere antagonism to test fungus, followed by Trichoderma harzianum-I(82.51%).
