| Abstract/Description: | The potentiality of six fungicides viz., propiconazole, mancozeb, difenoconazole, hexaconazole, combination fungicides, iprodione + carbendazim, carbendazim + mancozeb was evaluated against 220 isolates of Alternariaster helianthi an incitant of leaf blight of sunflower. Blight affected leaf samples were collected, isolated and cultured on sunflower leaf extract medium specific for A. helianthi. Isolates were collected from seven different sunflower growing states of India viz, Andhra Pradesh, Bihar, Karnataka, Maharashtra, Tamil Nadu, Telangana and West Bengal to maintain the wide sample range and to include major disease prevalent areas. The average inhibition of fungal growth recorded with the test fungicides ranged from 34.9 (mancozeb) to 66.2% (propiconazole). Among them, propiconazole inhibited the mycelia growth more than 50% irrespective of the isolates tested followed by combination fungicide of carbendazim + mancozeb. Out of all, four fungicides showed more than 50% inhibition of mycelia growth/fresh weight (propiconazole > comb fungicide carbendazim + mancozeb > comb fungicide ipriodine + carbendazim > difenoconazole > hexaconozole > mancozeb). Cluster analysis and principle component analysis revealed that highly sensitive isolates were clearly scattered from others and these were collected from the state of Karnataka viz., Ah-39, Ah-85, Ah-87, from Bihar Ah-153, Ah-154, Ah-159 and from Andhra Pradesh Ah-61, Ah-62, Ah-63, Ah-64, Ah-10, Ah-145, Ah-146. Propiconazole and combination fungicide of carbendazim + mancozeb were the efficient group observed according to ANOVA carried out with the average fresh weight data of the 220 isolates against fungicides. Spraying of propiconazole and combi fungicide carbendazim + mancozeb were found effective for management of leaf blight of sunflower under pot culture conditions. This study reinforces the potential of the azole group act as antifungal agent against A. helianthi |
