“…The black pepper plants were potted in vermiculite containing the Fusarium inoculum. The first symptoms of root rot were visible 60 days after inoculation, and plants from the above-mentioned two groups were then collected (Albuquerque 1961;de Castro et al 2016).…”

“…All plants displayed symptoms of Fusarium root rot such as blackened aspect of roots and collars and yellowish leaves (Albuquerque 1961) (Online resource 1). The blackened aspect of infected roots was most probably due to the production of toxins by the Fsp isolate (de Castro et al 2016) that caused the symptoms of the disease on aboveground plant tissues, such as yellowish leaves and dried branches, and ultimately plant death (Albuquerque 1961;Albuquerque et al 2001;de Castro et al 2016;Duarte and Albuquerque 2001). All non-inoculated plants that were sampled to generate an NIRL had very clear roots (Online resource 1).…”

“…The genetic variation between pepper genotypes in Brazil and the degree of susceptibility of currently available cultivars to the disease remain unknown, which makes it difficult to perform genetic control of fusariosis (Castro et al, 2016). As for chemical control, although the application of cupric fungicides can keep fusariosis of black pepper under control in propagators (Tremacoldi, 2010), there are restrictions on the use of fungicides due to environmental contamination and residues that may persist in the unprocessed products (Marín et al, 2008).…”

Fusariosis (Fusarium solani f.sp. piperis) is one of the most damaging diseases of black pepper crop in the Amazon zone and the application of organic materials to the soil may be an alternative to control this disease. Leaf residues of Piper aduncum were evaluated before and after the extraction of essential oil, as additives to the soil inoculated with Fusarium solani, in the survival and morphophysiological behavior of black pepper seedlings. The experiments were conducted at Embrapa Eastern Amazônia, Belém, PA. The effects of the by-products of the distillation of the essential oil of P. aduncum on the survival to fusariosis in black pepper seedlings and the effect of dry and crushed leaves of P. aduncum, preincubated in the soil, in the incidence of fusariosis and in the behavior of black pepper seedlings were evaluated. The addition of solid residues from P. aduncum oil extraction to the soil increased the survival of seedlings by 80% and in the presence of dry and crushed leaves of P. aduncum the survival was 83%. The net photosynthesis of the seedlings increased in the presence of residues of P. aduncum. The residues from the extraction of the essential oil of P. aduncum and its dry and crushed leaves, without oil extraction, have potential for use in the control of fusariosis in black pepper plants.Key words: Fusarium solani f. sp. piperis; Piper nigrum; residues from essential oil extraction Sub-produtos de Piper aduncum no controle da fusariose da pimenteira-do-reino RESUMO A fusariose (Fusarium solani f. sp. piperis) é uma das doenças mais prejudiciais à cultura da pimenteira-do-reino na Amazônia e a aplicação de materiais orgânicos no solo pode ser uma alternativa de controle dessa doença. Avaliou-se os resíduos foliares de Piper aduncum, antes e após a extração do óleo essencial, como aditivos ao solo inoculado com Fusarium solani, na sobrevivência e no comportamento morfofisiológico de mudas de pimenteira-do-reino. Os experimentos foram conduzidos na Embrapa Amazônia Oriental, Belém, PA. Foram avaliados os subprodutos da destilação do óleo essencial de P. aduncum na sobrevivência de mudas de pimenteira-do-reino à fusariose e o efeito de folhas secas e trituradas de P. aduncum, pré-incubadas no solo, na incidência de fusariose e no comportamento de mudas de pimenteira-do-reino. A adição de resíduos sólidos da extração de óleo de P. aduncum ao solo aumentou a sobrevivência de mudas à fusariose em 80% e na presença de folhas secas e trituradas de P. aduncum o incremento médio na sobrevivência foi de 83%. A fotossíntese líquida das mudas aumentou na presença dos resíduos de P. aduncum. Os resíduos da extração do óleo essencial de P. aduncum e de suas folhas secas e trituradas, sem extração do óleo, tem potencial de uso no controle da fusariose da pimenteira-do-reino.

Introducción. La pimienta es una especie de la familia de la Piperaceae, originaria de la Costa de Malabar, situada en Kerala al sur de la India. En Costa Rica, las principales plantaciones de pimienta se localizan desde Upala hasta Talamanca, e incluye toda la franja costera y la parte baja de Sarapiquí. Según estudios de factibilidad, el país cuenta con el potencial para producir pimienta con altos parámetros de calidad. Sin embargo, las enfermedades vasculares son una de las principales limitantes del cultivo.Objetivo. El objetivo de esta investigación fue el aislamiento e identificación molecular y morfológica de las especies de Fusarium asociadas al cultivo de la pimienta (Piper nigrum L.) en2 de las principales zonas productoras del país. Materiales y métodos. Se recolectaron treinta muestras de plantas enfermas de distintas fincas en las zonas de Sarapiquí y Guatuso, se describieron detalladamente los síntomas observados en el sistema radical y/o la base del tallo para cada una de las plantas recolectadas. Los veintiún aislamientos de Fusarium spp. obtenidos se identificaron molecularmente con la secuenciaparcial del gen Factor de Elongación 1α (EF-1α)y para la identificación morfológica se utilizaron los medios de cultivo PDA y Carnation Leaf-piece Agar (CLA). Resultados y conclusiones. Se confirmó la presencia de Fusarium oxysporum en las muestras provenientes de Sarapiquí, así como la presencia de Fusarium solani en ambas zonas muestreadas. Se reporta por primera vez, la presencia de las especies Fusarium concentricum y Fusarium proliferatum asociadas a la marchitez vascular.
