Alcachofra: nova planta hospedeira de Pratylenchus penetrans no estado de São Paulo, Brasil

Abstract

Relata-se a ocorrência do nematóide das lesões radiculares, Pratylenchus penetrans em alcachofra no Estado de São Paulo, Brasil. A estimativa da densidade populacional foi 224 espécimes no solo (250cm³) e 720 nas raízes (10g). As plantas atacadas mostravam-se com crescimento reduzido

First report of Pratylenchus penetrans (Nematoda: Pratylenchidae) associated with artichokes in Vietnam

“…Previous reports from other countries have highlighted the detrimental impact of P. penetrans on artichokes and other crops ( Castillo & Vovlas, 2007 ; Caubel et al , 1975 ; Rossi & Monteiro, 2001 ; Vovlas & Roca, 1981 ). Compared to these reports, the average density of 50 nematodes/100g of soil in this study denotes a significant infestation and suggests the possibility of serious harm to Vietnam’s artichoke yields ( Coosemans, 1975 ; Miller, 1975 ; Nyczepir & Becker, 1998 ; Olthof et al , 1973 ).…”

“…Pratylenchus penetrans is a primary causal agent of replant problems in many parts of the world ( Nyczepir & Becker, 1998 ). While the detrimental effects of P. penetrans on artichokes have been documented in several countries, such as Greece, Brazil, and France ( Castillo & Vovlas, 2007 ; Caubel et al , 1975 ; Rossi & Monteiro, 2001 ; Vovlas & Roca, 1981 ), its presence and impact in Vietnam, a significant producer of artichokes (particularly in Lam Dong, the most productive province in the country, where 162 hectares of artichokes are cultivated, yielding an impressive output of 8200 tons), remains unexplored to the best of our knowledge.…”
