| dc.description.abstract | Phyllody caused by phloem limiting phytoplasma is a very serious disease in most sesamum growing areas of Southern Karnataka. Sesamum phyllody is gaining importance in recent years because it causes an yield loss of upto 100 per cent. During survey phyllody infected plants showed excessive stunting, severe reduction in leaf size, reduced internodal length, excessive axillary proliferation and floral malformation like abnormal green structures in place of normal flowers. The incidence of sesamum phyllody ranged from 13.6 to 31.21 per cent during survey in sesamum growing areas of Southern Karnataka. The disease incidence was lowest in Ramanagar district with incidence of 13.6 per cent. Hassan district recorded the highest incidence of 31.21 per cent. Three genotypes showed resistant reaction, 27 genotypes showed moderately resistant reaction and 13 genotypes showed susceptible reaction against the phyllody disease under field conditions. Management of sesamum phyllody through two dates of sowing and vector (leafhopper) control revealed that lowest disease incidence (22.90 per cent) was observed in late sown crop compared to early sown crop (25.43 per cent). Seed yield was maximum (266.24 kg/ha) in late sown crop compared to early sown crop (249.15 kg/ha). Of the different treatment combinations, late sowing with seed treatment with imidacloprid 70 WS @ 5 g/kg + spray of acetamiprid 20 % SP @ 0.3 g/L and late sowing with seed treatment with imidacloprid 70 WS @ 5 g/kg + spray of imidacloprid17.8 % SL @ 0.5 ml/L at 20 days interval significantly reduced the disease incidence (18.51 and 19.78 per cent) and increased seed yield of 315.77 and 303.61 kg/ha respectively. | en_US |
