| A antracnose, causada pelo fungo Colletotrichum gloeosporioides, é uma doença foliar importante da pupunheira (Bactris gasipaes) nas fases de muda e planta jovem. O objetivo do trabalho foi avaliar a eficiência de fungicidas químicos no controle de antracnose em folhas de pupunheiras jovens, no Noroeste do Paraná. O ensaio foi conduzido com o delineamento experimental em blocos ao acaso, com cinco tratamentos com fungicidas e uma testemunha sem fungicida, com quatro repetições. Foram utilizados os fungicidas chlorotalonil (2 g L-1), chlorotalonil+tiofanato metílico (1 + 0,4 g L-1), tebuconazole (0,2 g L-1), azoxistrobina (80 mg L-1) e calda Viçosa (3 g L-1 de ácido bórico; 5 g L- de sulfato de cobre; 6 g L-1 de sulfato de zinco; 3,5 g L-1 de cal... |

| Leaf anthracnose, caused by Colletotrichum loeosporioides, is the most important disease of peach palm plants (Bactris gasipaes var. gasipaes) in nurseries in the Central and Southern Brazil. The objective of this study was to evaluate efficacy of some new formulations of fungicides for controlling anthracnose transplants in orchards. An assay with randomized block design was carried out, with five different fungicides and a control, with four replicates. Each replicated had 10 plants. The fungicides evaluated were: piraclostrobin + epoxiconazole (0,13 + 0,05 g.L-1), tetraconazole (0,1 g.L-1), tebuconazole (0,2 g.L-1 ), chlorotalonil (2 g.L-1) e chlorotalonil + Thiophanate-methyl (1 + 0,4 g.L-1). Each fungicide was sprayed seven times, at 15-day intervals.... |

| An experiment was established in Paranaguá, located in the costal region of the State of Paraná, in southern Brasil, in order to evaluate commercial yield of hearth-of-palm produced by Peach-Palm (Bactris gasipaes) established under the following four different initial spacings: T1 2x1m (5000 seedlings/ha); T2 3x1m (3333 seedlings/ha); T3 1,5x1x1m (8000 seedlings/ha); and T4 2x1x1m (6666 seedlings/ha). Mineral fertilizers (NPK) were applied at planting as well as subsequently. Results obtained by the time of the first cutting, 24 months after planting, allowed the following conclusions: a) the quantities of the NPK fertilizer used promoted changes in the chemical soil characteristics; b) commercial yield of hearth-of-palm improved as a function of stand... |

| Este é o primeiro registro do ataque de besouros (Curculionidae, Scolitinae), no Brasil, causando danos em plantios de nim, entre 7 e 10 anos, em Brejinho de Nazaré, Tocantins, constado em junho de 2009. Os insetos foram identificados como, Xylosandrus compactus (Eichhoff), Cryptocarenus diadematus Eggers, 1937 e Hypothenemus sp. Westwood, 1836. Os plantios atacados apresentavam crescimento abaixo do esperado para a região, baixa produção de sementes, desfolhamento acentuado e rebrota intensa nos ramos, seguida por morte de brotos jovens e/ou do ápice do ramo. A ação dos insetos provocou pontos de exsudação intensa de goma nos orifícios provocados. O fato tem similaridade com a síndrome denominada “declínio do nim”, relatada na África.doi:... |

| This research had as main objectives the evaluation of cedar’s seeds seed-borne fungi and the Fusariumsp. and Pestalotia sp. pathogenicities. For the fungi detection Potato Dextrose and Agar medium and Blottertest methods were used. For the pathogenicity tests, isolates of Fusarium sp. and Pestalotia sp. were used. The following fungi were observed: Pestalotia sp., Fusarium sp., Phomopsis sp., Colletotrichum sp., Macrophomina sp. and Cladosporium sp. The fungi observed in the highest frequencies were: Fusarium sp., Phomopsis sp. and Pestalotia sp. A reduction of the germination level was observed in seedlings from cedar’s seed inoculated with Fusarium sp. doi: 10.4336/2009.pfb.58.81 |

| Os objetivos neste trabalho foram identificar os fungos associados aos frutos e sementes de capororoca (Myrsine ferruginea Spreng) obtidos de diferentes lotes e verificar a incidência de fungos entre frutos verdes e maduros e nas sementes obtidas destes frutos. Para a detecção de fungos utilizou-se o método de papel-filtro (PF), sendo 400 frutos e 400 sementes para cada amostra, incubadas sob 12 horas luz negra/12 horas escuro, na temperatura de 20 ºC ± 1 ºC durante sete dias, avaliando-se a incidência (%) de fungos. Pôde-se verificar a possível transmissão dos fungos Alternaria sp., Cladosporium sp., Colletotrichum sp., Fusarium sp., Macrophomina sp. e Pestalotia sp. dos frutos para as sementes. Nos três lotes avaliados, Pestalotia sp. apresentou a maior... |

| Sphaeropsis sapinea is one of main pathogens that causes losses in commercial plantations of Pinusspp. Studies for control based on genetic resistance can be done by inoculating different monosporic isolates onpine populations and selectioning the resistant individuals. This work describes a methodology for pycnidia production in vitro and S. sapinea monoconidial cultures, using an agar-water medium with sterile pine needles. Four S. sapinea isolates were tested e pycnidia and mature conidia were observed after 14 days of incubation, under continuous fluorescent light, in BOD, at 25 °C. Pycnidia were triturated in sterile water and conidia germinated after two hours of incubation in water-agar, in BOD, at 25 °C. Germinated conidia formed colonies which... |

| The coast region of Paraná State, Brazil, has a great potential for growing of pupunha trees aiming palm heart production due to climate conditions. There were around one million pupunha trees planted at small farmers area, totalizing about 200 ha, in this region by the end of 2004. This fact confirms the specie as a sustainable and economicaly viable alternative for small farmers as long as the natural stands of juçara (Euterpe edulis) are raryng. This paper aimed to evaluate the palm heart production, at ages 24 and 39 months after planting, from plants growing instands varyng on plant density and soil class and considering processing as heart, ring and chopped. The experiment was set up in two areas located along the Alexandra-Matinhos Road (km 7 and km... |

| The aim of this research was to identify fungi associated with “pau-cigarra” seeds (Senna multijuga). Evaluation was carried out in nine lots composed of seeds collected from mother trees at Atlantic Rain Forest located in Antonina, Morretes and Guaraqueçaba municipalities, Paraná state, Brazil. Sanitary analysis was carried out by adopting blotter test and agar plate test. Morphological characteristics were used for fungi identification. It was observed higher fungi frequency contaminating seeds over filter paper (blotter test) compared with agar plate test. Helminthosporium sp., Alternaria sp., Ulocladium sp., Pestalotia sp., Penicillium sp., Trichoderma sp., Chaetomium sp. and Monilia sp. were the most important genus found associated with S. multijuga... |
