Abstract A description is provided for Synchytrium phaseoli-radiati. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Leguminosae (pigeon pea, Cajanus cajan; Crotalaria juncea; Phaseolus radiatus; P. mungo). DISEASE: Galls develop on leaves and stems of host plants and infected pigeon pea seedlings may suffer from wilting (52, 2790). GEOGRAPHICAL DISTRIBUTION: Asia (India). TRANSMISSION: No reports, but presumably by dissemination of resting spores.

ABSTRACT This study aimed to evaluate the reproduction of Pratylenchus zeae and P. brachyurus in leguminous plants used as cover crops. Seedlings of sunn hemp (Crotalaria juncea and C. spectabilis), pigeon pea cultivar IPR 43 (Cajanus cajan), dwarf velvet bean (Mucuna deeringiana), black velvet bean (Stizolobium aterrimum), and jack bean (Canavalia ensiformis) were inoculated with each nematode separately. Maize cultivar IPR 114 and soybean cultivar Pintado were used as controls to measure the viability of the inoculation of P. zeae and P. brachyurus. After 90 days of inoculation, the plants were collected and nematode g-1 root, final population, and reproduction factors (RF) were evaluated. The experiment was carried out at two different times of the year. The nematode’s RF on cover crops from treatments with the two Crotalaria species, dwarf pigeon pea, and black velvet bean were lower than one (bad host plants) in both experiments for P. zeae. For P. brachyurus, the lowest RFs were obtained for C. juncea, C. spectabilis, and pigeon pea, while the other plants presented RF values close to or higher than one in at least one of the experiments. Therefore, C. spectabilis, C. juncea, and C. cajan cultivar IPR 43 are antagonistic plants that represent useful options for rotation or succession systems that aim to control P. zeae and P. brachyurus.

O método tradicional da agricultura brasileira possui a característica de acelerar a degradação dos solos, reduzindo assim a produtividade a cada novo cultivo. Nos últimos tempos foram observadas tentativas de reverter esse processo e recuperar a fertilidade desses solos, por meio de práticas que utilizam processos naturais, a fim de reintroduzir nutrientes e elementos importantes ao solo. A associação, entre o pré-plantio de plantas da família Fabaceae e a utilização de estercos, vem sendo muito visada entre os agricultores que procuram por meios mais sustentáveis e econômicos de revigorar solos carentes em nitrogênio e matéria orgânica. Nesse sentido, a presente pesquisa teve como objetivo identificar qual a fonte de matéria orgânica de origem animal que potencializará ao máximo a nodulação de bactérias em cultivos de Crotalaria juncea L. e Cajanus cajan (L.) Millsp. A área da pesquisa ocorreu na casa de vegetação da Universidade Estadual de Alagoas, Campus Arapiraca. O delineamento experimental foi inteiramente casualizado com quatro tratamentos (solo sem esterco (controle), esterco bovino, esterco caprino, e esterco de aviário), com cinco repetições. Os dados foram submetidos a análise de variância por comparação de médias através do teste de Tukey a 5% de probabilidade pelo programa SISVAR. As variáveis analisadas foram altura, número de folhas, diâmetro do caule e número de nódulos. A aplicação de estercos não influenciou significativamente nas variáveis da Crotalaria juncea L. Os estercos bovino e caprino influenciaram de forma significativa nas variáveis da Cajanus cajan (L.) Millsp.

Abstract A description is provided for Fusarium udum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cajanus cajan. DISEASE: Fusarium wilt of pigeon pea, characterized by withering and drying up of green parts as if from drought. GEOGRAPHICAL DISTRIBUTION: India; the disease is soil-borne and restricted to the parts of India where the crop is grown. TRANSMISSION: A soil-borne disease but also transmitted on roots (Subramanian, 1971).

Abstract A description is provided for Synchytrium lagenariae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucurbitaceae (Cephalandra spp., Citrullus spp., Cucumis spp., Cucurbita spp., Lagenaria spp., Luffa spp., Trichosarthis spp.). DISEASE: Gall disease of cucurbits. Galls develop on stems, leaves, petioles, tendrils, inflorescences and fruits of host plants. GEOGRAPHICAL DISTRIBUTION: Asia (India). TRANSMISSION: Resting spores may be dispersed by movement of infected soil and local dispersal by zoospores swimming in water films may also occur.
