The present investigation was conducted during Kharif 2016-17 on field of Department of Agricultural Entomology, Agril. Research Station Badnapur. The experiment was planned in Randomized Block Design with cultivar BSMR 736 and gross plot size 7.20 x 4.50 m 2 with eight treatments replicated thrice with the object to study the sequential application of insecticides against against pigeonpea pod fly, Melanagromyza obtuse. All the insecticides were found to be significantly superior in recording minimum population of pod fly over untreated control. Among different insecticides, chlorantraniliprole followed by flubendiamide and Dimethoate recorded the least population of pod fly at 3,7 and 14 days after spray and which was statistically at par with the sequential application of insecticides as chlorantraniliprole followed by indoxacarb and acetamiprid in respect of reducing the population , pod damage of pod fly and higher grain yield. These findings indicate that the pigeonpea crop required two sprays of insecticides from pod initiation stage at 20 days interval for the management of pigeonpea pod fly, Melanagromyza obtusa.
Pigeonpea, Cajanus cajan (L.) Millsp is one of the important legume food crop of the semi-arid tropical and sub-tropical farming systems under varied agro-ecological environments. It is the second most important pulse crop of India after chickpea. India is the largest producer and also the largest consumer of pulses in the world. Assessments of twenty six restorers of pigeonpea was screened for resistance against major insect pests of pigeonpea under field conditions, at the ARS, Badnapur, VNMKV, Parbhani during Kharif -2017-18. Out of these three restorers viz. BDNHR-31-71, BDNHR-31-63, BDNHR-31-52 were found to be most promising restorers against H. armigera and M. obtusea by recording the range of H. armigera pod damage 7.53 -36.01 per cent and 10.07 -37.42 per cent due to M. obtusea as compared to check BDN 711 (36.02 and 38.45 per cent, respectively). As regards the morphological characters, it was observed that the growth habit and colour of flower and pod did not influence the pod borer infestation. Whereas, characters indicated that the maximum pod wall thickness, maximum number of seeds per pods, longest pods, maximum pod width characteristics were found to be least preferred as compared to minimum pod wall thickness, short pod lengths and short width pod which having more susceptible against pod borers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
