Effectiveness of different insecticides against sucking pests in brinjal

Abstract

An experiment was conducted to study the bio-efficacy of nine different insecticides (triazophos 0.08 %, imidacloprid 0.002 %, profenophos 0.05 %, diafenthiuron 0.05 %, clothianidin 0.025 %, cartap hydrochloride 0.05 %, thiamethoxam 0.025 %, thiacloprid 0.012 % and spiromesifen 0.024 %) again sucking pests viz., jassid and whitefly in brinjal (GBH 1) at Main Vegetable Research Station, Anand Agricultural University, Anand during Rabi season of 2011-12. Among different insecticides evaluated, thiamethoxam, diafenthiuron and thiacloprid emerged as most effective; profenophos, clothianidin and imidacloprid were mediocre; while cartap hydrochloride, spiromesifen and triazophos were found least effective against jassid. So far whitefly is concerned, spiromesifen, diafenthiuron and triazophos emerged as most effective; imidacloprid, profenophos and cartap hydrochloride as mediocre, while clothianidin, thiamethoxam and thiacloprid emerged as least effective. Diafenthiuron exhibited significantly higher brinjal fruit yield (350.57 q/ha), whereas triazophos and cartap hydrochloride hosted significantly lower fruit yield. The minimum and maximum per cent avoidable losses were recorded in diafenthiuron (0.00) and control (55.25), respectively. The highest Net ICBR (71.83) was obtained from the plots treated with profenophos followed by thiacloprid (56.10), cartap hydrochloride (43.93), imidacloprid (39.10) and diafenthiuron (27.69).

Efficacy of Insecticides and Biopesticides Against Major Sucking Insect Pests of Indian Bean <i>Lablab Purpureus</i> Var. <i>Typicus</i>

“…Razaq et al (2005) found that diafenthiuron gave high mortality of jassid and whitefly. The present observations also corroborated with those of Shaikh et al (2012) on spiromesifen and diafenthiuron against whitefly and diafenthiuron against jassid. Reddy et al (2014) reported >80% mortality A. craccivora in cowpea with dimethoate (0.06%).…”

“…and emamectin benzoate (27.47); and the least was 4.80 obtained withNSKE, azadirachtin (9.34) and B. bassiana (9.87). These results are partially in agreement with those ofShaikh et al (2012) on diafenthiuron;Anandmurthy et al (2017) observed maximum grain yield of cowpea 853 kg/ ha with dinotefuran followed by acetamiprid, spiromesifen and dimethoate. On the benefit cost ratio, acetamiprid (21.8) proved to be most economically viable followed by dimethoate (21.2) Choudhary et al (2017).…”

Bioefficacy of chemical insecticides against major sucking insectpests on grain legumes in India- A review

“…Thiamethoxam: Foliar application of thiamethoxam @100 g/ha was found significantly effective over control which recorded 1.25 whiteflies/leaf followed by seed treatment with thiamethoxam 500 FS @ 4.0 ml/kg seed in soybean (AICRP report on Soybean, 2005-06). Shah et al (2007) reported that thiamethoxam 25 WS @ 0.005 % was highly effective by recording lowest population of 2.60 whiteflies per plant and also recorded lowest MYMV incidence (10.7 %) in greengram. Verma and Kanwar (2009) reported that the lowest leafhopper population (0.84/ plant) was observed in seed treatment with thiamethoxam 70 WS @ 3 g /kg seed (0.84/plant) at 20 DAS in green gram.…”

Bioefficacy of Newer Molecules Insecticides against Tea Mosquito Bug, Helopeltis theivora Waterhouse under Laboratory Condition

“…Bioefficacy of newer insecticide molecules against Tea Mosquito Bug revealed that among all the treatments, Tolfenpyrad 15% EC treated tea shoots at 72 HAT had 100 percent adult mortality followed by Dinotefuran 20% SG (100.00%), Sulfaxaflor 21. The spray application of imidacloprid, thiamethoxam, and diafenthiuron effectively reduced the sucking pests population on chilli, brinjal and arecanut were reported by [1,16,17] and [18]. According to Venkateshalu and Mahesh [19], dinotefuran 20 % SG @ 30 g a.i./ha was found highly effective against sucking pests of Okra.…”
