| dc.description.abstract | "The effect of different formulations of Nomuraea Rileyi (Fariow) Samson and spray equipments in the management of tobacco caterpillar in groundnut and pod borer in chickpea was studied during kharif and rabi season during 2002-03 at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. Different formulations of N. rileyi viz., oil based, wettable powder and crude formulation were evaluated against third instar larvae of Spodoptera litura and Helicoverpa armlgera. The results indicated in vitro that mortality of S. litura and H. armigera reached 95.00 and 93.20 per cent, respectively after 10 DAT with oil based formulation of N. rileyi @ 2 x 10^ conidia per ml followed by wettable powder formulation and crude formulation. In groundnut crop ecosystem, different formulations of N. rileyi and spray equipments were evaluated, the results indicated that oil based formulation of N. rileyi with knapsack sprayer recorded significantly higher mycosis (47.43%), followed by wettable powder and crude formulation. With respect to cost economics concerned oil based formulation of N. rileyi @ 2 x 10"" conidia per ha recorded net returns of Rs. 17,360 with B:C ratio of 2.8, which is next best to RPP. In chickpea ecosystem, among different formulations of N. rileyi and spray equipments, oil based formulation of N. rileyi with knapsack sprayer recorded significantly higher mycosis (42.96%) with lowest per cent pod damage (26.43%). With respect to cost economics concerned oil based formulation of N. rileyi with knapsack sprayer recorded net returns of Rs. 11,952 with B:C ratio of 2.9, which is next best to RPP. The highest persistent toxicity (PT) value was recorded in oil based formulation of N. rileyi by recording 0.9 x 10^ CPU (colony forming unit) per 5 leaves followed by wettable powder and crude formulation." | en_US |
