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.

    Ecofriendly Management of Maydis Leaf Blight (Helminthosporium maydis) of Maize
    (Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2017) Bharti, Prasoon; Chand, Phool
    Maize (Zea mays L.) popularly known as "corn” is queen of cereals due to its high yield efficiency, important human nutrient, basic element of animal feed etc. Maydis leaf blight disease of maize causes considerable losses to the maize crop. The present investigations on “Ecofriendly management of maydis leaf blight (Helminthosporium maydis) of maize” were undertaken to explore the possibilities of botanicals and fungicides for the management of maydis leaf blight (Helminthosporium maydis) disease. Among five fungicides evaluated at different concentrations (50, 100, 150, 200, 250) in vitro against H. maydis by poison food technique, propiconazole showed 100 per cent inhibition of mycelia growth were recorded at 150, 200 and 250 ppm followed by mancozeb which caused 92.37 per cent inhibition at 250 ppm and minimum inhibition was recorded in copper oxychloride at all the concentrations (70.63, 72.26, 75.55, 76.82 and 79.48). Of the six plant extracts evaluated by poison food technique for their inhibitory effect on the growth of H. maydis, the neem leaf extracts shoed strong inhibitory effect at all concentration followed by parthenium at 10and 20 per cent and garlic cloves at 30, 40 and 50 per cent concentrations. Out of the 128 genotypes screened under artificial inoculated conditions, 29 genotypes appeared resistant, 44 genotypes were moderately resistance to maydis leaf blight, 52 genotypes were rated as moderately susceptible and 3 genotypes found susceptible. All fungicides and plant extracts screened under in vitro, were further evaluated under field conditions against maydis leaf blight disease. Three sprays of propiconazole and mancozeb proved to the most effective fungicides recording the lowest disease incidence 34.75 and 53.20 per cent, respectively as against control treatment (79.67 PDI). However, neem leaf extracts and garlic cloves @ 10% showed maximum (51.30 and 59.10) disease incidence.
