Efficacy and economics of certain new generation novel insecticides against legume pod borer, Maruca vitrata (Geyer) on pigeonpea (Cajanus cajan L.)

Abstract

Two field experiments were conducted during Kharif, 2010 and 2011 to find out economical control measures against legume pod borer, Maruca vitrata (Geyer) on pigeonpea. Experimental results showed that the per cent inflorescence damage due to Maruca was lowest in chlorantraniliprole 18.5 SC (2.08%) and flubendiamide 39.35 SC (3.64%), followed by spinosad 45 SC (6.21%) as against control (31.18%) with 93.3, 88.3 and 80.1 per cent reduction over control respectively. Similarly, pod damage due to legume pod borer was lowest in chlorantraniliprole (4.30%), flubendiamide (6.03%) and spinosad (8.80%) as against control (47.28%) with 90.9, 87.3 and 81.4 per cent reduction over control respectively. Highest grain yield was recorded in chlorantraniliprole treated plots (686.1 kg/ha) with 127.5 per cent increase over control, followed by flubendiamide (595.8 kg/ha) and spinosad (589.0 kg/ha) with 97.6 and 95.3 per cent increase over control (301.6 kg/ha) respectively. The cost effectiveness of chlorantraniliprole and flubendiamide was also high and very favorable with incremental costbenefit ratios of 1: 4.64 and 1: 4.50 respectively, followed by indoxacarb (1: 3.67), emamectin benzoate (1: 3.13) and spinosad (1: 2.97).

Bio-efficacy of certain new insecticides against pod borer complex in pigeonpea (Cajanus cajan L.)

“…The results are in close agreement with the findings of Satpute and Barkhade (2012) who reported chlorantraniliprole (rynaxypyr) 20 SC @ 40 g a.i./ha as the most promising insecticide against pod borer complex of pigeonpea and to give highest yield of 1752 kg/ha. Similar studies conducted by Sreekanth et al (2015) revealed that the per cent inflorescence and pod damage due to M. vitrata in pigeonpea was lowest in chlorantraniliprole 18.5 SC treated plot over others, with highest grain yield of 686.1 kg/ha, 127.5% more over control. Barad et al (2013) found emamectin benzoate 5 WG at 9.4 g a.i.…”

Efficacy of Commercial Insecticide for the Management of Cowpea Pod Borer (Maruca Vitrata) on Cowpea (Vigna Unguiculata (L.) Walp) Under Field Condition in Chitwan, Nepal

“…The novel insecticide like Chlorantraniliprole, Flubediamide and Spinosad were highly effective against Lepidopteran pests (Chatterjee and Mondal, 2012). A group researchers also reported highest yield of pigeonpea with use of Chlorantraniliprole followed by Flubendiamide (Sreekanth et al, 2015). Similar result was obtained in the research carried out (Mohanraj et al, 2012;Sapkal et al, 2018).…”

“…Similar was the result of damage percent of fruit by cowpea pod borer on weight basis with highest damage in control plot (30.66%) followed by neem treated plot (11.24%) and lowest damage was observed in Chlorantraniliprole 18.5% SC plot (4.57%). A group researchers reported that the mean percent pod damage was found to be significantly low in plots treated with chlorantraniliprole (2.1%) and flubendiamide (3.6%), followed by spinosad (6.2%), while 31.2% damage was noticed in the untreated control (Sreekanth et al, 2015). The results obtained in the present investigation were in agreement with the findings of Haritha, (2008), who reported that chlorantraniliprole (0.009%) recorded least pod damage (1.6 %) due to M. vitrata on pigeonpea than control (5.3%).…”

Evaluation of Insecticides for the Management of Litchi Fruit and Shoot Borer

“…Devi and Singh (2016) reported that flubendiamide was effective against yellow stem borer Scirophaga incertulas walker. Similarly, Dhaka et al (2015) and Deshmukh et al (2010) found less damage caused by pod borer, Helicoverpa armigera (hubner) in vegetable pea, legume pod borer Maruca vitrata (Geyer) in pigeonpea (Sreekanth et al 2015), spotted stem borer, Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) in maize (Arunkumara et al 2017) when treated with flubendiamide. Vijayraghavendra and Basavangoud (2017) when treated sapota with the flubendiamide found that the yield was significantly higher than control against sapota fruit borer, Phycita erythrolophia.…”
