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).

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).

Avaliou-se a germinação e o tamanho inicial das plântulas de pepino (Cucumis sativus), melancia (Citrulius lanatus), melão (Cucumis melo) e mogango (Cucurbita pepo) cujas sementes foram submetidas as condições do teste padrão de germinação, em rolos de papel toalha, umedecidas com as seguintes quantidades de água: 1,0; 1,5; 2,0; 2,5; 3,0 e 3,5 vezes o peso do papel. Os graus de umedecimento que proporcionam as maiores porcentagens de germinação para pepino e melancia são 2,0 a 2,5 vezes o peso do papel. Para o melão os melhores resultados de germinação são conseguidos com graus de umedecimento de 2,0 a 3,0 vezes o peso do papel, enquanto que para o mogango as quantidades de água requeridas são maiores do que para as demais espécies, devido ao maior tamanho de suas sementes. O aumento da quantidade de água no substrato proporciona aumentos no tamanho da parte aérea das Cucurbitaceas, porém o comprimento das raízes pode sofrer reduções variáveis, de acordo com a espécie estudada, quando a umidade está acima da faixa considerada ideal.

Three separate field trials were conducted to determine the most appropriate planting dates for intercropping cucumber (Cucumis sativus), summer squash (Cucurbita pepo), and muskmelon (Cucumis melo) with strawberry (Fragaria ×ananassa), and their effect on ‘Strawberry Festival’ strawberry yields. ‘Straight Eight’ cucumber, ‘Crookneck’ summer squash, and ‘Athena’ muskmelon were planted every 15 days from 25 Jan. to 23 March. None of the three intercropped species affected strawberry yield up to 60 days before the end of the season on 25 March. Cucumber yield responded quadratically to planting dates, rapidly increasing from 25 Jan. to 23 Feb. and declining afterward. Warmer temperatures favored summer squash yield, with the highest yields when planted on 23 Feb. or later. Muskmelon yields decreased as air temperatures increased, and the best planting dates were between 25 Jan. and 9 Feb. In summary, cucumber and summer squash seemed to be favored by planting under warmer temperatures, whereas muskmelon thrives under cooler weather.

ABSTRACT We announce the draft genome sequences of six strains of Lactococcus lactis (EKM101L, EKM102L, EKM201L, EKM203L, EKM501L, and EKM502L). These candidate plant probiotics were isolated from surface-sterilized seeds of Cucumis sativus L. (cucumber), Cucumis melo L. (cantaloupe), and Cucurbita pepo var. turbinate (acorn squash). They display beneficial activities, including biocontrol.

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.

Abstract A description is provided for Cunninghamella echinulata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On decaying flowers of Cucurbita pepo, dung and soil. DISEASE: Reported pathogenic to Spanish pumpkin (Cucurbita maxima) at Chandigarh and neighbouring villages in the Punjab, India by Grover (1965). Symptoms recognizable when the flowers begin to die off gradually. Diseased flowers do not open properly. Infected flowers are covered with the cottony mycelium of the pathogen and infected fruits may become detached from the plant and continue to rot on the soil. Leaves and stalks are also frequently infected. GEOGRAPHICAL DISTRIBUTION: World-wide (mostly tropical countries). TRANSMISSION: Air borne; may survive in fragments of mummified pumpkin fruit up to 32 months.
