dc.description.abstract | The present investigations were carried out during the Rabi 2017-18 and 2018-19 seasons at Student’s Instructional Farm, A. N. D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). The four major insects viz., Jassid (A. biguttula biguttula), White fly (Bemacia tabaci), Hadda beetle (Henosepilachna vigintioctopunctata) and brinjal shoot and fruit borer (L. orbonalis) were recorded. The maximum population of brinjal shoot and fruit borer 5.37 & 4.95 larvae /plant was recorded in 15th SW of 2017-18 & 2018-19 followed by 4.68 & 4.92 larvae/plant of brinjal shoot and fruit borer was recorded in 14th SW of 2017-18 & 2018-19 and minimum population of brinjal shoot and fruit borer 0.31 & 0.35 larvae /plant was recorded in 21st SW of 2017-18 & 2018-19 followed by 20th SW of 2017-18 & 2018-19 larval population of brinjal shoot and fruit borer 0.63 & 0.59 larvae/plant. Among the various insecticides evaluated against brinjal shoot and fruit borer (L. orbonalis), Spinosad 45 SC @ 73g a.i./ha treated plots showed lowest infestation and gave higher fruit yield (253.12) followed by Indoxacarb 14.5 SC (229.33). The boipesticide NSKE 5% most effective followed by Bacillus thuringensis and Beauveria bassiana. The highest cost: benefit ratio was obtained from NSKE 5% (1:24.40) followed by Indoxacarb 14.5 SC (1:24.13) which were also economical than other treatments. On the basis of per cent shoot infestation Spinosad 45 SC was found most effective insecticide with lower infestation followed by Indoxacarb 14.5 SC > NSKE 5% >Chlorfenapyr 1.9 EC >Bacillus thuringensis >Karanj seed extract>Beauveria bassiana >Neem oilcompared to control, all the treatments were found effective and significantly superior over the control. Based on per cent fruit infestation on brinjal, Indoxacarb 14.5 SCwas most effective followed by Spinosad 45 SC>Chlorfenapyr 1.9 EC > NSKE 5% >Bacillus thuringensis >Karanj seed extract>Beauveria bassiana>neem oil, control. Indoxacarbwas found significantly superior to other insecticides. Spinosad and Chlorfenapyr were found next effective insecticides. | en_US |
