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 epidemiology and management of pearl millet rust incited by Puccinia substriata var. pennicillariae
    (CCSHAU, 2016) Annu; Kushal Raj
    Rust caused by Puccinia substriata var. penicillariae is one of the major disease affecting both forage and grain production in pearl millet. The present investigation was undertaken to study the role of weather factors in relation to development of pearl millet rust on three hybrids viz., HHB 197, HHB 223 and HHB 67 Imp at three different dates of sowing (early, recommended and late). Among three hybrids rust severity was more in HHB 223 on 2nd date of sowing (recommend sown) and AUDPC was more in HHB 223 corroborating with HHB 197 but lesser in HHB 67 Imp. Apparent infection rate was variable at different stages depending upon environmental conditions corroborating to the stage of crop. Maximum periodical progression of the disease was observed during last week of October, Amongst 228 entries of coordinated trials, none of the entry was free from rust severity, 10 entries showed 0.1-20% rust severity, 48 entries showed 20.1-40% rust severity, 80 entries showed 40.1-60% rust severity, 67 entries showed 60.1-80% rust severity and 23 entries showed more than 90% rust severity. Amongst 276 entries of state trials, 39 entries were free from rust severity, 188 entries showed 0.1-20% rust severity, 71 entries showed 20.1-40% rust severity, 15 entries showed 40.1-60% rust severity, two entries showed 60.1-80% rust severity and none entry showed more than 80% rust severity. Various plant product, bioagent and fungicides were evaluated under screen house and field condtions. Propiconazole 25% EC @ 0.1% managed the rust most effectively and significantly both under screen house and field conditions. Maximum Grain yield (514.7 kg/acre), test weight (8.13 g) and Benifit: Cost ratio 3.98: 1 was observed in Propiconazole 25% EC (0.1%) sprayed plot followed by Hexaconazole 5% EC (0.1%) and proved most economical in managing the rust of pearl millet.
