In vitro evaluation of fungicides and plant extracts against the fungi associated with seeds of nine chickpea varieties

Abstract

A total of nine species of fungi were found to be associated with seeds of nine
varieties of chickpea. The isolated fungi were Alternaria alternata (Fr.) Keissler,
Aspergillus flavus Link., A. niger Van Tiegh., A. fumigatus Fresenius., A. nidulans
Eidam, Curvularia lunata (Wakker) Boedijn, Penicillium Link., Rhizopus stolonifer
(Ehrenb.: Fr.) Vuill and Trichoderma viride Pers. Five fungicides viz., Bavistin 50
WP, Dithane M‐45, Greengel 72 WP, Ridomil MZ Gold and Tall 25 EC at 100, 200,
300, 400 and 500 ppm were evaluated against the test fungi. Tall 25 EC were
found most efficient inhibitor which completely inhibited the radial growth of
the test fungi followed by Bavistin 50 WP, Dithane M‐45 and Greengel 72 WP.
Antifungal properties of ethanol extracts of Azadirachta indica A. Juss., Allium
sativum L., Citrus medica L., Datura metel L. and Psidium guajava L. at 5, 10 and
20% concentrations were evaluated against the test fungi. Allium sativum L. was
found most efficient inhibitor of the test fungi followed by D. metel L., A. indica A.
Juss., C. medica L. and P. guajava L.
