In the imperial Gazetteer of India 1878, Pusa was recorded as a government estate of about 1350 acres in Darbhanba. It was acquired by East India Company for running a stud farm to supply better breed of horses mainly for the army. Frequent incidence of glanders disease (swelling of glands), mostly affecting the valuable imported bloodstock made the civil veterinary department to shift the entire stock out of Pusa. A British tobacco concern Beg Sutherland & co. got the estate on lease but it also left in 1897 abandoning the government estate of Pusa. Lord Mayo, The Viceroy and Governor General, had been repeatedly trying to get through his proposal for setting up a directorate general of Agriculture that would take care of the soil and its productivity, formulate newer techniques of cultivation, improve the quality of seeds and livestock and also arrange for imparting agricultural education. The government of India had invited a British expert. Dr. J. A. Voelcker who had submitted as report on the development of Indian agriculture. As a follow-up action, three experts in different fields were appointed for the first time during 1885 to 1895 namely, agricultural chemist (Dr. J. W. Leafer), cryptogamic botanist (Dr. R. A. Butler) and entomologist (Dr. H. Maxwell Lefroy) with headquarters at Dehradun (U.P.) in the forest Research Institute complex. Surprisingly, until now Pusa, which was destined to become the centre of agricultural revolution in the country, was lying as before an abandoned government estate. In 1898. Lord Curzon took over as the viceroy. A widely traveled person and an administrator, he salvaged out the earlier proposal and got London’s approval for the appointment of the inspector General of Agriculture to which the first incumbent Mr. J. Mollison (Dy. Director of Agriculture, Bombay) joined in 1901 with headquarters at Nagpur The then government of Bengal had mooted in 1902 a proposal to the centre for setting up a model cattle farm for improving the dilapidated condition of the livestock at Pusa estate where plenty of land, water and feed would be available, and with Mr. Mollison’s support this was accepted in principle. Around Pusa, there were many British planters and also an indigo research centre Dalsing Sarai (near Pusa). Mr. Mollison’s visits to this mini British kingdom and his strong recommendations. In favour of Pusa as the most ideal place for the Bengal government project obviously caught the attention for the viceroy.

    Seasonal incidence and control of maize stem borer, Chilo partellus (Swinhoe) through newer insecticides on maize in Bihar
    (Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2017) Kumar, Ram; Alam, Tanweer
    In order to study the seasonal incidence and control of maize stem borer, Chilo partellus (Swinhoe) through pest monitoring, screening of different maize genotypes and relative efficacy of insecticides, a series of field experiments were conducted during Kharif 2016 at the research farm, Tirhut College of Agriculture, Dholi, Muzaffarapur, (Bihar). Results pertaining to different aspects of the present study viz., seasonal incidence, screening of different maize genotypes and foliar spray as well as granular application of insecticides applied against maize stem borer on maize crop have been abstracted below: The activity of maize stem borer on maize commenced from 33rd standard week (2nd week of August, 2016) and continued to 44th standard week (4th week of October, 2016) with maximum maize stem borer population (2.4 larvae/plant) in the 38th standard week (2nd week of September, 2016) when the corresponding maximum, minimum temperature (oC), relative humidity (%) at 07 hrs and 14 hrs, rainfall (mm) and sunshine (hr) were 30.7, 25.4, 98.0, 86.7, 22.2 and 3.5, respectively. The per cent infestation has been initially observed in 33rd standard week (2nd week of August, 2016) and continued to 44th standard week (4th week of October, 2016) with maximum per cent infestation of 32.0 per cent during 38th standard week (2nd week of September, 2016) when the corresponding maximum, minimum temperature (oC), relative humidity (%) at 07 hrs and 14 hrs, rainfall (mm) and sunshine (hr) were 30.7, 25.4, 98.0, 86.7, 22.2 and 3.5, respectively. Among all the genotypes screened against Chilo partellus under artificial infestation condition, IIMRQPMH 1608, FQH 106 and IIMRQPMH 1606 were found least susceptible in respect to mean per cent infestation, mean leaf injury, mean per cent stem tunnelling, mean tunnel length and mean number of exit holes/plant; while the genotypes IIMRQPMH 1604, IIMRQPMH 1502 and IIMRQPMH 1610 were found susceptible. All the insecticidal treatments under test, were found significantly superior over control, however the treatment Chlorantraniliprole 20 SC followed by Carbofuran 3G was found to be the most effective and was statistically at par with Flubendiamide 480 SC followed by Carbofuran 3G. The foliar application in sequence with whorl application of Carbofuran was found to be more effective than foliar applications alone. The crop protection measures applied against maize stem borer, Chilo partellus proved profitable as indicated by B: C ratio.
