About the Cover

Among the different fungicides tested for their efficacy against Colletotrichum leaf blight, Hexaconazole, Propiconazole, Tricyclazole, Thiophenate methyl and Carbendazim + Mancozeb each @ 0.1 % completely inhibited growth and sporulation of the pathogen in vitro. Out of twenty different cultivars of turmeric screened for their reaction to the disease, Allampuram, Allepey supreme, Cochber, Kuchipuri, Prabha, SB 10723, SB 10735, SB 10746, SB 10843, Tekurpeta found resistant to disease while Arunachal local, Pratibha and Salem were moderately resistant. Jalpalguri local, RH 5, SB 10757 Sikandarabad local, Sudarshana, Suguna, Suranjana showed susceptible reaction to the leaf blight (Ref: Jaydeep Kadam, Gadre UA, Sudhir Navathe, Agale RC.

RESEARCH

Exploration of fungicides and phytoextract against Fusarium Oxysporum f. sp. Gladioli causing corm rot of gladiolus


Kadam JJ, Agale RC, Rite SC, Pandav SM

All the fungicides tested in vitro were found effective in inhibiting the mycelial growth of Fusarium oxysporum f. sp. gladioli. Difenconazole (0.1%) and Propiconazole (0.1%) completely inhibited the mycelial growth of Fusarium oxysporum f. sp. gladioli followed by Thirum (85.22%), Captan (82.77%), Carbendazim (65.33%) and Copper oxychloride (50.77%). Least inhibition of the test fungus was recorded due to Mancozeb (32.00%) and Thiophenate methyl (28.66%). Among the different plant extract tested against the same fungus, complete inhibition of mycelial growth was achieved due to 10 per cent Jatropha followed by Soapnut (37.00%), Neem seed kernel extract (35.00%), Cassia (26.44%), Neem leaf extract (22.00%), bulb extract of Garlic (17.22%). Clove, Castor, Nilgiri, Cinnamon and Sarpagandha were found least effective against the fungus.
