Uromyces ciceris-arietini. [Descriptions of Fungi and Bacteria].
Abstract A description is provided for Uromyces ciceris-arietini. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cicer arietinum and Trigonella polycerata. DISEASE: Rust of chick pea or gram. First symptoms appear as small, round or oval cinnamon brown pustules which coalesce. Severe disease causes premature defoliation and considerable reduction in crop yield. GEOGRAPHICAL DISTRIBUTION: Africa (Kenya, Morocco); Asia (India); Europe (Bulgaria, Corsica, Cyprus, France, Greece, Italy, Portugal, Rumania, Spain, Turkey, U.S.S.R., Yugoslavia); N. America (Mexico). (CMI Map 235.) TRANSMISSION: Urediospores airborne. It has been suggested in India that dissemination probably occurs from the hills to the plains where there is apparently no local source of infection. The rust is said to perpetuate in the uredo state during summer on Trigonella polycerata in the hills where climatic conditions are suitable (42: 251). Urediospores survived for only 2-4 weeks at room temperature in soil in pots, but at 5-7°C for a period of 48 weeks (27: 110; Saksena & Prasada, 1955).
