Author(s): Vishwa Prakash, DV Singh, Rajendra Singh, Gopal Singh and Suraj Kumar
Abstract: A field experiment was carried out to study the efficacy of some novel insecticide against maize stem borer, Chilo partellus (Swinhoe) at Crop Research Centre of SardarVallabhbhai Patel University of Agriculture and Technology, Meerut during Kharif 2016. The imidacloprid 17.8 SL was found most effective treatment followed by carbaryl SL, dimethoate 30% EC @ 1000 ml/ha (3.9 per cent) and acephate 75% @ 500 ml/ha 3.71 per cent infestation, which was at par each other respectively. The highest infestation was recorded in control plot (24.8 per cent). This was significantly higher than rest of the treatments and responsible for economic damage in maize crop. The highest grain yield (38.1 q/ha) was obtained from the imidacloprid 17.8 SL treated plot with maximum cost benefit ratio (1:8.75) followed by from carbaryl SL treated plot (36.8 q/ha) with cost benefit ratio (1:5.93).
