Byadagi Dyavanoor during kharif season of 2002-03 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to evaluate the organic amendments and indigenous products for the management of H. armigera. Studies on the effect of organic amendments on H. armigera revealed that among the different organic amendments, soil application of neem cake @ 1 t/ha was very effective in recording lowest eggs (0.69), larval population (0.62) and lowest fruit damage (6.5%) being on par with vermicompost @ 2 t/ha. Next best treatments were neem cake @ 0.5 t/ha + 50 per cent RDF, vermicompost @ 1 t/ha + 50 per cent RDF and RDF, Neem cake @ 1 t/ha recorded highest green chilli yield of 83.47 q/ha being on par with RDF (79.00 q/ha) and RPP (89.33 q/ha). These were followed by vermicompost @ 2 t/ha + 50 per cent RDF (76.00 q/ha) and neem cake @ 0.5 t/ha + 50% RDF (72.00 q/ha). Highest B:C ratio of 3.88 was noticed in neem cake @ 1 t/ha from among the organic amendments evaluated. Studies on the effect of indigenous sprays on H. armigera in chilli revealed that from among the indigenous products NSKE 5 per cent recorded lowest mean egg (1.15/plant), larval population (1.01/plant) and per cent fruit damage in NSKE 5 per cent (7.57%). This was followed by garlic chilli kerosene extract 3 per cent, NSKE 5 per cent + cow urine 10 per cent and NSKE 5 per cent + garlic extract 10 per cent. The efficacy of NSKE 5 per cent (79.32 q/ha), NSKE 5 per cent + cow urine 10% (78.00 q/ha), garlic chilli kerosene extract 3 per cent (76.23 q/ha), NSKE 5 per cent + garlic extract 3 per cent (83.67 q/ha) remained same in recording higher yield of green chilli. All the organic amendments evaluated either alone or their half doses in combiantion with 50 per cent RDF were safe to coccinellids {Menochiilus sexmaculatus Fab and Coccinella septumpunctata Thumb.) and Chrysoperal carnea Steph. in chilli ecosystem. All the indigenous sprays included in the study were safe to coccinellids and C. carnea except garlic chilli kerosene extract 3 per cent."ennullThesis
