Abstract:
Bio efficacy of some botanical products of Azadirachta indica, Allium sativum, Seima walchii, Artimesia, Nicotiana
tobacum and Datura stramonium against the shoot borer (Peridaedala sp.) of Dendrobium nobilae was evaluated under
polyhouse conditions. The minimum shoot borer infestation was recorded for Achook (NSKE) 1500 ppm and Neem oil
0.03% (~ 4% and ~ 5% respectively), after 7 days of treatment. Maximum per cent infestation of shoot borer was recorded
by Seima walchii leaf extract 10% (~ 12% at 7th days after treatment).
