dc.description.abstractIn order to study the screening of different maize genotypes, effect of different intercropping system and seed treatment with insecticides and relative efficacy of insecticides against control of maize stem borer, Chilo partellus (Swinhoe), a series of field experiments were conducted during Kharif 2018 at the research farm, Tirhut College of Agriculture, Dholi, Muzaffarapur, (Bihar). Results pertaining to different aspects of the present study viz., screening of different maize genotypes, effect of different intercropping system and seed treatment and foliar spray as well as granular application of insecticides applied against maize stem borer on maize crop have been abstracted below: Among the different maize genotypes screened against C. partellus; APH2, followed by BML (C), FQH-140 (15.89), APH1 (16.57) and QQPMH-41 were found least susceptible while the genotypes susceptible check, Pratap QPM Hybrid 1 (C) (39.81) followed by FQH-148 (38.25). The remaining genotypes tested showed intermediate position and were considered as moderately susceptible Present findings showed that among different intercropping systems maize intercropped with cowpea recorded lowest per cent plant infestation, per cent cob damage, per cent dead heart, minimum length of stem tunnel and highest yield. With regard to different seed dressing materials, imidacloprid recorded lowest per cent plant infestation, per cent cob damage, per cent dead heart, minimum length of stem tunnel and highest yield. Among all the insecticides tested against C. partellus; Carbofuran 3G @ 7 kg/ha, Rynaxypyr (20 SC) @ 0.3 ml/lit and Flubendiamide (480 SC) @ 0.2 ml/lit were found to be the best treatments against maize stem borer, C. partellusen_US
