Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    DISTRIBUTION AND BIOCONTROL POTENTIAL OF ENTOMOPATHOGENIC NEMATODES AGAINST SOME LEPIDOPTEROUS PESTS
    (CSKHPKV, Palampur, 2014-01) Vashisth, Sumit; Chandel, Y.S.
    ABSTRACT Survey for entomopathogenic nematodes (EPNs) was conducted in ten districts of Himachal Pradesh during 2011-13. In all, 930 soil samples from 131 locations were analysed for the occurrence of the nematodes. The frequency of occurrence of these nematodes was very low (3.82%). The nematodes were found in five locations i.e. Sangla (Distt. Kinnaur), Kamand (Distt. Kullu), Rajgarh (Distt Sirmour), Rajour and Sutkar (Distt. Chamba). These localities are situated in mid hill/high hill zones of the state. The nematodes were recovered from fruit orchards only having lighter soils. The nematodes from all the locations were identified as Heterorhabditis. Nematode cultures from different locations were considered as isolates and were designated as Sangla isolate, Kamand isolate , Rajgarh isolate , Sutkar isolate and Rajour isolate . Former three isolates, along with one commercial isolate i.e. H. indica (procured from NBAII, Bangluru) were evaluated for their pathogenic effects against Spodoptera litura, Helicoverpa armigera, Plutella xylostella and Agrotis segetum in Petri plates/soil/screen house. All these three local isolates including the commercial isolate proved pathogenic variably to different insect-pests. In screen house testing on cabbage, Rajgarh isolate was found highly effective against S. litura, H. armigera and P. xylostella. The virulence of these isolates was considered of the medium level. The bacterium, Photorhabdus luminescence was associated with all the isolates and proved non pathogenic to Achroia grisella when tested alone. Besides, host invasion studies in A. grisella revealed maximum penetration through natural openings, other than mouth. For in vivo mass production of local EPNs, Corcyra cephalonica, A. grisella and Bombyx mori were used. The average yield of IJs/larva was minimum (23020-26030) in C. Cephalonica and maximum in B. mori (463080-546840) for different EPNs. For in vitro production, chicken offal medium was used. The yield was maximum for Rajgarh isolate (17.70 x 106 IJs/flask).
