Abstract:

The field experiments were conducted to determine the comparative efficacy of different management practices against Chilo partellus (Swinhoe) in Kharif maize in western Uttar Pradesh. For present studies entitled.Evaluation of efficacy of some novel chemical insecticides against stem borer, Chilo partellus (Swinhoe) in maize., were conducted in randomized block design with three replications of six treatments during Kharif, 2011 at crop research centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.). The incidence of stem borer was initiated just after the 1st week of germination which increased thereafter and attained the economics threshold level 15 days after sowing, the mean per cent incidence of C. Partellus ranged from 11.12 to 17.78 per cent. Among all the treatments the seed treatment with Spinosad 45%SC spray @ 200ml/ha was performed best with maximum larval population reduction of Chilo partellus (82.95 per cent reduction After First Spray (AFS), 87.26 per cent reduction After Second Spray (ASS) and 87.57 per cent reduction After Third Spray (AFS) per cent dead hearts (1.66 per cent at 30 DAS and 2.33 per cent at 45 DAS) and percent life injury (1.33 per cent at 30 DAS and 1.66 per cent at 45 DAS). Fallowed by Bifenthrin10%EC spray @ 400ml/ha (75.53 per cent reduction After First Spray (AFS), 77.56 per cent reduction After Second Spray (ASS) and 78.17 per cent reduction After Third Spray (AFS) per cent dead hearts (2.33 per cent at 30 DAS and 3.33 per cent at 45 DAS) and percent life injury (1.66 per cent at 30 DAS and 2.33 per cent at 45 DAS) and minimum Imidachloprid17.8% SL spray @ 250 ml/ha (58.50 per cent reduction After First Spray (AFS), 61.52 per cent reduction After Second Spray (ASS) and 63.01 per cent reduction After Third Spray (AFS) per cent dead hearts (7.33 per cent at 30 DAS and 7.66 per cent at 45 DAS) and percent life injury (6.20 per cent at 30 DAS and 6.66 per cent at 45 DAS). The maximum grain yield of 45.1 q/ha and net profit of Rs. 24345 /ha obtained from the treatment of Spinosad and yield of 38.44 q/ha and net profit of Rs. 22486 /ha obtained from the treatment of Bifenthrin. The minimum grain yield of 28.41 q/ha and net profit of Rs. 7145 /ha was recorded in untreated control.
