Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970.

    Studies on cultural variability and management of bottlegourd anthracnose caused by Colletotrichum lagenarium (Pass.) Ellis and halsted
    (CCSHAU, 2017) Ankit Kumar; Narender Singh
    Studies on variability and management of Colletotrichum lagenarium (bottle gourd anthracnose) through fungicides and plant extracts were carried out. Survey was conducted in ten villages of five districts of Haryana and minimum per cent disease intensity on leaves was observed in Arjaheri village of Karnal district, whereas on fruits per cent disease intensity was minimum in Dadupur village of same district. In the variability studies, potato dextrose agar medium was found best for growth at 6.5 pH and 30ᵒC temperature. Among various isolates Karnal (CL2) and Kaithal (CL3) isolates were found fast growing. Among six plant extract tested, neem leaf extract (20% w/v) was found most effective in inhibiting (60.36%) mycelial growth. Seven fungicides were tested and found 100 percent inhibition of growth of fungus by Carbendazim (50% WP) and propiconazole (25% EC). Fungicides viz. carbendazim and propiconazole along with two plant leaves extracts viz., neem and garlic were evaluated. Carbendazim (50% WP) at 100 ppm concentration was found most effective in reducing anthracnose disease with, neem and garlic leaf extracts being less effective. Twenty four germplasm lines were screened and the three lines viz., K-92420, GH-3 and GH-11 were found resistant to the disease.
