The present investigation was carried out to study the efficacy of different novel insecticides and bio-pesticides against stem borer Scirpophaga incertulus (Walker) during kharif 2015-16 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Efficacy of newer insecticides (fipronil 5 SC, cartap hydrochloride 50SP,chlorpyriphos 20 EC, imidacloprid), one biopesticide (Neemarin 1500 ppm) and one bio-control agent (Trichogramma japonicum) were evaluated against yellow stem borer Scirpophaga incertulas (Walk.) in Basmati rice. The stem borer recorded as dead heart ear heads ranged from 4.85 to 10.55 per cent and white ear head showed that it was recorded on 38th standard weak. All the treatments were found significantly effective in reducing the infestation of stem borer and increasing the yield compared with control. Application of fipronil 5 SC was the most effective treatment in reducing the stem borer infestation at all observational interval resulting highest grain yield The results of paddy yield depicted in table 3, showed that the plots treated with fipronil 0.3 GR @ 25 kg/ha gave the highest yield (45.56 q/ha).

Abstract The present investigation was based on the management of Yellow stem borer which is a major pest of Basmati rice crop in India. All the treatments were applied to control this pest when it reached on its ETL level. The data recorded one day before of first spray and 3, 7, 10 days after of each spray. The observation revealed that all the treatments were found significantly superior over untreated control. Among the all treatments Fipronil 5 SC was found most effective followed by Imidacloprid 17.8 SC, Cartap hydrochlorid 4 G. Among the bio-pesticides B. bassiana was most effective after the chemical pesticides followed by M. anisopliae and V. lacani. The field treated with fipronil 5 SC produced the highest grain yield (38.35 q/ha) and Imidacloprid 17.8 SC was placed on second place with 37.26 q/ha grain yield followed by Thiamethoxam 25 WG (36.05q/ha) and Cartap hydrochloride 4G (33.87 q/ha).

The present investigation was carried out to study the “Eco friendly management of yellow stem borer, Scirpophaga incertulas (Walker) on paddy in western plain zone of Uttar Pradesh” in randomized block design with three replications and seven treatments at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The yellow stem borer, S. incertulas (Walker) was recorded as major pest. The incidence of S. incertulas (Walker) was recorded on the incidence of yellow stem borer Scirpophaga incertulas (Walker) showed that it was recorded on 26th standard week for the first time and continued till second week of November i.e. 46th standard week. The infestation of stem borer recorded as dead heart/ white ear head ranged from 0.85 to 15.25 per cent during the crop season i.e. Kharif 2017 and positive correlated with all the other weather parameters.

Background: In India, out of the total loss incurred by different insect pests of paddy, 25 to 30 per cent damage is done by stem borer alone. Many conventional insecticides though have been evaluated against stem borers, yet, most of the chemicals have failed to provide adequate control. Hence, the present study aimed to evaluate the efficacy of some newer molecules of insecticides and bio-control agents.Methods: Field trials were conducted to record the seasonal incidence and to evaluate the efficacy of insecticides and bio-control agents against the stem borer species in rice during Kharif and Rabi. Result: Field experiments revealed that during Kharif 2018, chlorantraniliprole 18.5 SC was highly effective with 92.98 and 91.24 per cent reduction of stem borer infestation over control at vegetative and reproductive stages, respectively and recorded a high yield of 5720 kg/ha followed by spinetoram 11.7 SC with 83.16 and 80.82 per cent reduction of stem borer over control at vegetative and reproductive stages, respectively. During Rabi 2019, spinetoram 11.7 SC was highly effective with 92.36 and 93.73 per cent reduction of stem borer infestation over control at vegetative and reproductive stages respectively and recorded a high yield of 4570 kg/ ha, followed by chlorantraniliprole 18.5 SC with 84.60 and 91.48 per cent reduction of stem borer at vegetative and reproductive stages, respectively. The difference in the efficacy of insecticides during Khaif, 2018 and Rabi, 2019, might be due to shift in the species occurrence of stem borer, with a dominant occurrence of yellow stem borer (80.61%) in Kharif 2018 and pink stem borer (70.00%) in Rabi, 2019. The bio-control agent Trichogramma japonicum exerted minimum reduction of stem borer with a low grain yield of 3946.6 kg/ha.
