Diplodia ear rot of corn is primarily caused by the fungus Stenocarpella maydis in the United States. Stenocarpella macrospora is a closely related fungus present in the U.S. but primarily associated with Diplodia leaf streak. S. macrospora is recognized as a major ear rot pathogen in South America and South Africa, but has infrequently been associated with ear rot in the U.S. This brief presents the first reports of Diplodia ear rot in Illinois and Tennessee. This is also the first confirmation of S. macrospora causing ear rot in the U.S. in over 60 years. Accepted for publication 19 May 2016. Published 15 June 2016.

Abstract A description is provided for Setosphaeria rostrata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On graminicolous hosts and on Amaryllis, Carica, Cucumis, Jasminum, Nicotiana and from soil. DISEASE: Causes leaf spots, foot rot of wheat (56, 2446), seedling blight of Cynodon (46, 2051), leaf blight of Eleusine (46, 1263), damping-off of sugarcane seedlings (50, 1562l), stalk rot (53, 2167) and ear rot of maize, blackening of seeds and seed germination failure (34, 91; 51, 2435). GEOGRAPHICAL DISTRIBUTION: Africa (Mauritius, Nigeria, S. Africa, Sudan); Asia (China, India, Israel, Pakistan); Central America (Puerto Rico); Europe (Denmark); North America (USA). TRANSMISSION: The fungus is soil-borne and can survive saprophytically for a long period (43, 398). Also seed transmissible (51, 2435). Conidia are produced abundantly in moist conditions and are dispersed by wind and rain, and act as a source of primary infection. Many grasses and weeds act as collateral hosts (39, 321).

IMI). DISEASES: Causing seedling bright, food rot, stunting and hypertrophy of shoots ('bakanae') of rice; associated with seed rot, seedling blight, ear rot, root and stalk rot of maize and sorghum; stem rot and top rot ('pokkah boeng') of sugar-cane (also reported on sorghum); seedling blight, root rot and pink boll of cotton and seedling blight of wheat. Also recorded causing wilt in Crotalaria and decay to fruit of banana, pineapple and tomato. GEOGRAPHICAL DISTRIBUTION: Widespread in both humid and sub-humid temperate zones and extending into sub-topical and tropical zones in Africa, Asia, Australasia & Oceania, Europe, Central America & West Indies, and North & South America (CMI Map 102, Ed.3). TRANSMISSION: Both seed and soil-borne (13: 262) as well as by air-borne spores produced on over-wintered plant debris where the pathogen may retain its viability for over two years (12: 532).

Abstract A description is provided for Puccinia sorghi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pycnia and aecia on some 30 species of Oxalis including O. corniculata (some of these by artificial inoculation only). Uredia and telia on Euchlaena mexicana, E. perennis and Zea mays. DISEASE: Rust of maize causing chlorosis and death of leaves and leaf sheaths. GEOGRAPHICAL DISTRIBUTION: The aecial infection is limited in distribution to temperate regions in Europe, the United States of America, Mexico and South Africa, with one record from Nepal (C.P. News 7: 59, 1961). The uredial and telial stages are practically co-extensive with the distribution of their hosts (CMI Map 279). In the tropics it is less common than Puccinia polysora below 4, 000 feet. TRANSMISSION: By air (Phytopathology 47: 101-7), by seed (Reyes, Philippine J. Agric. 18: 115-128; 1953) and probably also by infected or contaminated material.
