dc.description.abstractConsidering the emphasis on organic farming in recent years, efforts were made to evaluate the botanical formulations against diamondback moth under laboratory and against cabbage pests under field condition. Experiment was carried out during August to December 2018-19 at College of Horticulture, Udyanagiri, University of Horticultural Sciences (UHS), Bagalkot. Twenty days old cabbage seedlings sprayed with 10, 20 and 40 per cent cow urine did not exhibited any phytotoxicity effect. Hence, the lower dose of 20 per cent cow urine was selected for preparation of botanical extracts. Ninteeen freshly prepared cow urine based botanical formulations along with cow urine @ 10 and 20 per cent alone and untreated control were assessed for their efficacy, antifeedent and oviposition deterrent properties against diamondback moth (DBM), Plutella xyllostella (L.) under laboratory condition. The laboratory studies indicated that, Neem seed powder (NSP), Pongamia seed powder (PSP), Vitex leaf powder (VLP), NSP + PSP + Chilly fruit (CF), NSP + PSP + VLP + CF + Garlic clove (GC) exhibited relatively higher levels of efficacy (85.93, 78.89, 79.26, 85.93 and 89.63 per cent respectively), antifeedent (84.49, 77.37, 77.37, 79.95 and 81.36 per cent respectively) and oviposition deterrent activity (78.80, 76.81, 74.69, 81.08 and 85.35 per cent respectively) against DBM and were significantly superior to other test products. In field investigation, these top five botanical formulations obtained from laboratory experiment were selected and evaluated against cabbage pests along with Azadirachtin 10000 ppm @ 1ml/l, IIHR recommended IPM and untreated control. The results revealed that, all the tested botanical formulations showed good efficacy against cabbage pests as compared to control. Among which, combination of NSP + PSP + VLP + CF + GC was significantly better for management of cabbage pests such as DBM, Spodoptera litura, aphids, head borer (5.28% damage), recording significantly highest yield (55.47 t/ha) and B:C ratio (4.96) followed by NSP + PSP + CF which recorded 51.78 t/ha yield and 4.58 B:C ratio. Similarly, the botanicals did not affect natural enemies viz. coccinellids and spiders during the course of study.en_US
