Abstract A description is provided for Fusarium oxysporum f.sp. melonis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucumis melo. DISEASE: Causes a destructive wilt of muskmelon and cantaloupe. The casaba or winter melon is resistant (e.g. var. Honey Dew). Infection occurs on seedlings (pre-emergence and post-emergence damping-off) and older plants (leaf chlorosis, stunting and generai wilt). Streaks appear on the stems up to 0.6 m long; they become necrotic and bear the salmon-pink sporulating masses. In some cases stem cracks develop and a brownish exudate forms. The vascular elements become orange-red and the fruit is much reduced in size. The formae speciales of F. oxysporum from muskmelon and watermelon (Citrullus lanatus) will each attack the seedlings of both hosts, but older plants are susceptible only to their own f.sp. Generally the virulence of a given isolate is greater on its original host (12: 744; 27: 307; 31: 473; Leach, 1936). Cucumber (Cucumis sativus) and marrow (Cucurbita pepo) are resistant (39: 117). GEOGRAPHICAL DISTRIBUTION: Generai in North America (U.S.A., Canada) and Europe. Also reported from Asia (Formosa, Iraq, Japan, Philippines) and Australasia (Australia). TRANSMISSION: Through soil and seed (Leach, 1936).

Abstract A description is provided for Fusarium oxysporum f.sp. cucumerinum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucumis sativus. DISEASE: A temperate and subtropical wilt of cucumber which caused up to 40% losses in Florida in 1949. The pathogen causes pre-emergence and post-emergence damping-off and wilt of older plants. In Florida mature plants with runners may first show wilt in a single crown branch, followed by collapse of the whole plant. Vascular necrosis may extend into the vine for 6-8 nodes (35: 265, 266). A cortical decay, absent from older plants, occurs in seedlings. In England, wilt symptoms have been described as beginning in the lower leaves and the vascular system of the lower nodes becomes prominent, standing out as white lines (45, 3013). GEOGRAPHICAL DISTRIBUTION: In U.S.A., in glasshouses in the north and in the field in California,. Florida, Mich., N. Mex., Texas and Wis. The disease has also been reported from: Africa (S. Africa); Asia (Iraq, Japan, Thailand); Australasia (Australia); Europe (England, France, Germany, Netherlands, Norway, U.S.S.R.); North Amenca (Canada). TRANSMISSION: Presumably through soil.

Cladosporium Cucumerinum

Abstract A description is provided for Cladosporium cucumerinum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucumis sativus, Cucumis melo, Cucurbita pepo. DISEASE: Scab of Cucurbits, especially cucumber (Cucumis sativus), muskmelon and cantaloupe (C. melo), and pumpkin, squash and marrow (Cucurbita pepo). Symptoms are most severe on the young fruit where deeply sunken lesions are formed, up to 1 cm diam. and with a gummy exudate. On older fruit infection is restricted by the host reaction and results in the formation of brown, cork-like scabs. Foliage infection (necrotic, water-soaked spots sometimes with a gummy exudate) is not very destructive. Sporulation on the leaf tends to be sparse. At favourable temperature the apical shoots of young plants are killed back. GEOGRAPHICAL DISTRIBUTION: Widespread in N. America and Europe; also in parts of Africa, S. and E. Asia, Panama and Trinidad. The disease has not been reported from Australasia or S. America (CMI Map 310, ed. 2, 1968). Additional records not mapped are Israel and Lebanon. TRANSMISSION: Probably by air dispersed conidia, and the pathogen survives between crops on host debris. Although seed treatment has been recommended (34: 341; 44, 311) C. cucumerinum is probably rarely seed-borne (47, 3058).

Durante los años 2008 y 2009 se muestrearon plantas de melón (Cucumis melo L.), sandía (Citrullus lanatus Thumb), calabacita (Cucurbita pepo L.) y pepino (Cucumis sativus L.), así como especímenes de mosquita blanca (Bemisia tabaci Genn.) en diferentes localidades de los Estados de Nuevo León, Coahuila y Durango. Después de extraer el ARN, las muestras se analizaron con la técnica de RT-PCR, con oligonucleótidos específicos que amplifican regiones conservadas que codifican para las proteínas p22, de choque térmico y la cápside del virus del amarillamiento y enanismo de las cucurbitáceas (CYSDV). Se detectó el virus CYSDV en plantas de melón y sandía, así como mosquita blanca colectada en varias localidades. Se encontraron 26 muestras positivas al virus CYSDV de 129 plantas de la familia Cucurbitaceae en los tres estados estudiados de la región Norte-Centro de México. Los productos de amplificación fueron clonados y secuenciados, y se compararon con las secuencias disponibles en el GenBank. Las secuencias obtenidas a partir de las muestras positivas presentaron de 96 a 100 % de similitud con secuencias de Estados Unidos, España y otros países.
