Bio-efficacy of different plant leaf extracts and bio-control agents against Fusarium oxysporum f. sp. ciceri

Abstract

Chickpea (Cicer arietinum L.) is one of the most important legumes in India. The fungal disease Fusarium oxysporum f. sp. ciceri Butler is dominant and destructive in large areas of chickpea production. Leaf extracts from seven different plant species were evaluated in vitro against the pathogen at concentrations of 5% and 10%. Among these leaf extracts, neem was the most effective against Fusarium oxysporum f. sp. ciceri, followed by garlic, pipal, palmarosa, tulsi, aloe vera, and ashoka, which prevent the growth of fungi. Of the biopesticides, Trichoderma harzianum (64.00%) showed the best result in Fusarium oxysporum f. sp. ciceri, followed by T. viride (51.33%), T. koningii (44.67%), T. longibrachiatum (30.67%), T. hamatum (23.33%), and Chaetomium globosum (18.67%).
