Contenido :  ABSTRACT. Meloidogyne ethiopica is considered to be one of the most economically important emerging nematode species, reported to cause crop losses to several hosts worldwide. The significance of this species is due to its high virulence and degree of polyphagia, in addition to persisting on weed hosts within agricultural fields. This study evaluated the host status of 36 different weed species, confirming the polyphagia habit of M. ethiopica and indicating which plant species may be alternative hosts for this plant nematode. Weed species were inoculated with 5000 eggs and second-stage juveniles (J2) of M. ethiopica, with gall index (GI), nematode/g root (Nem/g), and reproduction factor (RF) value determined following 60 days post inoculation. The data obtained indicate that many weed species may be excellent hosts for M. ethiopica. Plants deemed susceptible (RF ≥ 1.0) were: Acanthospermum australe, Amaranthus deflexus, A. hybridus, A. spinosus, A. viridis, Bidens pilosa, B. subalternans, Cardiospermum halicacabum, Commelina benghalensis, Cynodon dactylon, Euphorbia heterophylla, Galinsoga parviflora, Ipomoea grandifolia, I. nil, I. purpurea, Leonurus sibiricus, Nicandra physaloides, Oxalis corniculata, Portulaca oleracea, Raphanus raphanistrum, Sida rhombifolia, Solanum americanum, S. pseudocapsicum, S. sisymbriifolium, Sonchus oleraceus and Talinum paniculatum, representing 72.2% of the species assessed. The species Conyza bonariensis, Cyperus rotundus, Digitaria hor... Presentar Todo

Contenido :  Abstract: Black foot disease of grapevines is a problem in most grape-producing regions of the world. This disease affects both young and mature plants, which show retarded growth and eventually die. Species of Cylindrocarpon have been identified as the causal agent of this disease. Fungal isolates were obtained from roots of symptomatic plants and plantlets from commercial vineyards in Uruguay. Morphological characteristics on malt extract agar were recorded, and DNA purified. Internal transcribed spacer (ITS) rDNA was amplified with primers ITS 4 and ITS 5 and the amplified fragments were sequenced. Phylogenetic analyses were done with sequences from Uruguay and sequences from GenBank using PAUP* (Phylogenetic Analysis Using Parsimony). Six phylogenetic groups were found that matched six previously known taxa. These groups were supported by morphological characteristics. Isolates were assignable to Campylocarpon and Cylindrocarpon species. Ca. pseudofasciculare, C. destructans var. crassum, C. liriodendri, C. macrodydimum, C. olidum var. crassum and C. pauciseptatum represent new records for Uruguay. This work is the first step towards a better understanding and management of black foot disease in local conditions.
