Evaluation of phenyl pyrazole for the managaement of yellow stem borer Scirpophaga incertulas Walker in rice

Abstract

Field experiment was conducted at Banaras Hindu University research farm, Varanasi, on hybrid rice variety PHB 71 during Kharif season of 2012 to study impact of granular formulation of phenyl pyrazole on rice yellow stem borer, Scirpophaga incertulas (Walker). Results revealed that in terms of efficacy against stem borer, overall performance of various spraying insecticidal treatments based on the mean indicated that treatment with Fipronil 0.6 per cent GR @ 60g a.i./ha was the most effective and significantly superior over all other treatments in reducing the dead hearts to minimum level of 3.40 per cent. Fipronil 0.6 per cent GR @ 50g a.i./ha stood second in order of effectiveness which recorded 4.45 per cent dead hearts. The Carbofuran 3 GR @ 750g a.i./ha. proved least effective in which higher per cent of dead hearts of 5.08 were observed. The untreated control recorded 6.88 per cent dead hearts.How to view point the article : Satyanarayana, Paidi, Raghuraman, M. and Santeshwari (2014).

Bioefficacy of Carbosulfan 6G against the Rice Stem borer, Scirpophaga incertulas (Walker) in Karaikal District, Union Territory of Puducherry

“…ha -1 followed by carbosulfan 6G @ 1000 g a.i. ha -1 against the rice yellow stem borer S. incertulas; similar experiment was conducted by Hugar et al (2010). Yadav and Gupta (2020)…”

“…In India, S. incertulas has earned the dubious distinction of holding the top position as the most significant pest, as it can attack the rice crop at all stages of its growth (Pasulu et al, 2002;Yadav and Gupta, 2020). The presence of rice stem borers, which infest rice from seedling to maturity, poses a significant obstacle to rice production (Dale, 1994;Hugar et al, 2010;Pathak, 1975). During the vegetative stage, the larvae of Scirpophaga incertulas result in dead hearts, while in the reproductive stage, they lead to the formation of white ear heads (Hugar et al, 2010).…”

The prime importance of applying insecticides arises when the pest population surpasses the economic threshold level.…”

“…The utilization of insecticides has a favorable impact on rice yields (Abro et al, 2013), and insecticides are frequently highly effective, rapidacting, convenient and cost-effective, rendering them the most potent tools in pest management. The new insecticides should possess effectiveness in minimizing pest damage, cost-effectiveness, biodegradability and safety for natural enemies and other non-target organisms (Hugar et al, 2010).…”

Assessment of Biopotency of Fipronil 80 WG against Stem Borer and Leaf Folder in Paddy Ecosystem

“…Singh et al, (2015), reported about the effectiveness of fipronil 5 SC in reducing the infestation of insect pests in rice. Satyanarayana et al (2014) also studied the efficacy of different granular insecticides against YSB in Varanasi (India) and reported that field performance of the treatments were in the order of fipronil 0.6 GR @ 60 g a.i./ha > fipronil 0.6 GR @ 40 g a.i./ha > cartap HCl 4 GR @ 750 g a.i./ha > fipronil 0.6 GR @ 50 g a.i./ha > fipronil 0.3 GR @ 60 g a.i./ha > carbofuran 3 GR @ 750 g a.i./ha. Dhaka et al (2009) has documented the effectiveness of fipronil against rice stem borer both as foliar application and granular application, due to its systemic activity and persistent toxicity.…”
