A field experiment was conducted over two consecutive growing seasons (Kharif- 2018 and Kharif- 2019) and the recorded data were pooled to find out the best seed treatment as a control measure for shoot fly incidence and its influence on grain as well as fodder yield of barnyard millet (variety PRJ-1) was estimated. Six different seed dressing treatments viz., imidacloprid 600 FS @ 5ml/kg seed, carbosulfan 25 ST @ 20g/kg seed, neem oil @ 5ml/kg seed, thiamethoxam 70 WS @ 2g/kg seed, acetamiprid 20 SP @ 2g/ kg seed, chloropyriphos 20 EC @ 5ml/kg seed, were imposed on barnyard millet seeds. The pooled data from both the years revealed significant reduction in dead hearts (ranged from 4.38 to 44.44 per cent) across the treatments including untreated control. Minimum (0.46) number of eggs laid per plant was recorded when the seeds were treated with imidacloprid 600 FS @ 5ml/kg seed followed by thiamethoxam 70 WS @ 2g/kg seed (0.53) whereas, maximum (1.69) number of eggs per plant was found in plants raised from untreated seeds. The pooled grain yield data showed 56.97 per cent increase over control when seeds were treated with imidacloprid 600 FS @ 5ml/kg seed along with highest net return (Rs. 47,412.00) and B:C ratio (1.75) which was followed by 46.90 per cent increase in grain yield when seeds were treatment with thiamethoxam 70 WS @ 2g/kg seed with net return of Rs. 42,720.08 and B:C ratio 1.58. Two consecutive years’ investigation revealed seed treatment with imidacloprid 600FS @ 5ml/kg as a promising treatment to control the shoot fly damage and at the same time resulted in higher yield of grain and fodder in barnyard millet in Uttarakhand hilly areas.
