ABSTRACT
The leaf blight of gladiolus caused by Alternaria dianthicola was found to be major disease under agro climatic conditions of Konkan region of Maharashtra. During the present study, eight fungicides, seven plant extracts and four fungal bioagents were evaluated in in vitro to test their efficacy in inhibiting the growth of Alternaria dianthicola. Among the different fungicides tested in vitro mancozeb (0.2%), difenconazole (0.05%) and propiconazole (0.05%) were found most effective against the fungus. The antagonistic effect of fungal bioagents on Alternaria dianthicola revealed that Trichoderma viride and T. harzianum significantly inhibited mycelial growth of the fungus. The bulb extract of Allium sativum was found to be most effective in inhibiting the growth of the test fungus followed by Azadirachta indica and Ocimum sanctum.
