Abstract
Field trials were conducted in infected sites at two locations: the Millet Breeding Station, TNAU, Coimbatore and at the Regional Research Station, Aruppukottai, to test the combination of promising treatments for the management of pearl millet downy mildew using the highly susceptible HB3 pearl millet. Pearl millet seeds were exposed to sporangial shed of Sclerospora graminicola and then sown. Incidence of downy mildew was recorded at 30, 45, 65 days after sowing (DAS) and the per cent disease was calculated. The yield of pearl millet was also recorded during the harvest and calculated as kg/ha. Seed treatment (ST) with Apron 2 g/kg + Ridomil 0.6% foliar spray (FS) 20 DAS was by far the most effective in reducing the incidence of pearl millet downy mildew disease to a minimum of 4.65% from a maximum of 66.09% in the control. Seed treatment with Pseudomonas fluorescens 10 g/kg (ST) ranks next (10.47%) followed by ST with Trichoderma viride at 4 g/kg (17.15%) and FS with the culture filtrate of Fusarium longipes (103 conidia/ml) 20 DAS (29.76%). The grain yield recorded 910 kg.ha in ST with T. viride, ST with Pseudomonas fluorescens (880 kg/ha).
