Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    POWDERY MILDEW (Erysiphe cruciferarum Opiz ex Junell) OF INDIAN MUSTARD, ITS RELATIONSHIP WITH WEATHER AND MANAGEMENT
    (AAU, Anand, 1995) Solanki, V. A.; Patel, B. K.
    Powdery mildew is one of the important diseases, causing considerable yield loss under epiphytotic conditions in Indian mustard. Hence, to overcome this constraint. Powdery mildew (E. cruciferarum Opis ex Junell) of Indian mustard, its relationship with weather and management was studied in Gujarat for three consecutive rabi seasons (1992- 93, 1993-94 and 1994-95). Morphological studies on imperfect states showed the profuse, hyaline, whitish and slightly flexous mycelium on an adaxial surface, 3-5 celled, mostly straight conidiophores (av. length 73.39 ± 10.42 iim) with moderately straight foot cells (av. length 24.52 ± 4.1 µ m)were observed with basal septum away from the branching point. Ellipsoidal-cylindrical conidia without fibrosin bodies were horned singly with average length, breadth and L/B index of 36.82 ± 4.82, 14.51 ± 2.33 pn and 2.60 ± 0.51, respectively. Frequently branched germ tubes at the conidial ends and multilobed appressoria were also observed. Perfect stage was not observed on Indian mustard as well as on weed Argemone mexicana. Morphological characters of powdery mildew fungus of both the hosts were more or less matched with each other. The newly employed (for the first time) RED ink of LUXOR sketch pen as a stain showed greater performance with better clarity than the cotton blue. Among various agroclimatic zones of. Gujarat, conidial length and breadth were found quite variable. Higher conidial length and L/B index were observed at low relative humidity with high temperature agroclimatic zone (i.e. at S.K. Nagar). Several herbicides and insecticides were screened for their toxicity In vitro. Oxadiazon showed acute and typical disintegration of conidia and insecticides viz., triazophos and methyl-o-dematon accumulated the internal organelles with slight disintegration of conidial wall.
