Abstract

Five fungicides. namely Tecto. Benlate. Bayton. Topsin and Derosal were evaluated for their effect aan seed germination and control of major seed-borne pathogens of sunflower. Two sunflower cultivars. AO-1 and NK-212. naturally infected with important seed-borne fungi were trealed with these fungicioe u 1.5.2.0.2.5.3.0 g/kg. All the fungicides under study controlled the seed-borne fungi and increased the germination of sunflower seed to various levels fecto and Benlate in both the cultivars gave belter performance in reducing fungal population and increase in seed germination. Topsin and Derosal also reduced the fungal population at higher dosage but there was no considerabic improveinent. inl germination. The use of fungicides (@ 2.5 g/kg provided almost complete elimination of fungs and 8-10 per cent increase in seed germination as compared to the use of fungicide 12 2 g/kg
