Sobrevivência de Xanthomonas axonopodis pv. manihotis em manipueira sob condi??es ambientais
Theodoro, Gustavo de Faria;Maringoni, Antonio Carlos;
Pesquisa Agropecuária Brasileira , 2002, DOI: 10.1590/S0100-204X2002000700008
Abstract: the objective of this work was to evaluate the survival of a xanthomonas axonopodis pv. manihotis (xam) strain, resistant to streptomycin sulfate, in "manipueira" (cassava residue) incubated under environmental conditions, in three periods of the year (march, july and october 2000). a semi-selective culture medium and the polymerase chain reaction (pcr) or biological amplification (bio-pcr) methods were used. the ph and the total acidity of the "manipueira" were determined during the incubation period. the strain survived less than 24 hours in the three periods of the year. the pcr or bio-pcr method was not effective in monitoring the strain survival in "manipueira", as it showed contradictory and unreliable results. an increase in total acidity and a decrease in ph of the "manipueira" were observed, explaining the survival behavior of xam strain.

Scientia Agricola , 2000, DOI: 10.1590/S0103-90162000000300011
Abstract: an experiment was carried out to evaluate the in vivo and in vitro sensibility of a clavibacter michiganensis subsp. michiganensis isolate (cmm) to the products kasugamicyn cloridrate, fulusulfamide and oxytetracicline. in the in vitro tests, the inhibition formed around the discs of filter papers soaked with the chemicals was evaluated, for concentrations of 0, 1, 10, 100 and 1000 mg ml-1, 24 h after the installation of the experiment. in the in vivo evaluation, two experiments were installed under greenhouse conditions, with tomato plants cv. angela hiper and two methods of inoculation: leaf spray and stem injury. in both experiments, the plants were sprayed with 0.06 ml l-1 of kasugamicyn chloridrate, 0.025, 0.05 and 0.075 ml l-1 of fulusulfamide and 0.40 g l-1 of oxytetracycline, twice before and twice after the inoculations, at intervals of 5 to 7 days. the incidence of diseased leaves (inoculation by leaf spray) and the severity of the symptoms in the plants inoculated by stem injury was evaluated. the cmm isolate was in vitro sensitive to kasugamicyn chloridrate, fulusulfamide and oxytetracycline in the respective concentrations of 1000, 100 and 10 mg ml-1. only the oxytetracycline promoted a lower incidence of diseased leaves in the plants inoculated by leaf spray. none of the chemicals had success in the disease control (inoculation by stem injury). the fulusulfamide, in all concentrations, was toxic to the leaves of tomato plants.
Efeito de doses de nitrogênio na severidade da murcha-de-curtobacterium em cultivares de feijoeiro comum
Theodoro, Gustavo de Faria;Maringoni, Antonio Carlos;
Summa Phytopathologica , 2006, DOI: 10.1590/S0100-54052006000200006
Abstract: it was evaluated the influence of nitrogen (n) levels in the severity of bean bacterial wilt, caused by curtobacterium flaccumfaciens pv. flaccumfaciens, in the cultivars iac pyat?, ipr 88 uirapuru, and scs 202 guará, under greenhouse conditions. the treatments consisted of the recommended level of n and rates 25% and 50% lower or higher than that, using urea as n source. the higher levels of n increased the progress of the bacterial wilt only in the cultivar iac carioca pyat?. the n content in the plant aerial part did not interfere with the dry mass weight of any cultivars tested.

Pesquisa Agropecuária Brasileira , 2002,
Abstract: O objetivo deste trabalho foi avaliar a sobrevivência de um isolado de Xanthomonas axonopodis pv. manihotis (Xam), resistente ao sulfato de estreptomicina, em manipueira incubada em condi es ambientais, em três épocas (mar o, julho e outubro de 2000). Foram utilizados um meio de cultura semi-seletivo para o isolamento de X. axonopodis pv. manihotis e a técnica de rea o de polimerase em cadeia (PCR) ou de amplifica o biológica (BIO-PCR). Foram determinados o pH e a acidez total da manipueira durante o período de incuba o estudado. O isolado sobreviveu por um período inferior a 24 horas, nas três épocas do ano. A técnica de PCR ou BIO-PCR n o foi eficaz em monitorar a sobrevivência do isolado em manipueira, pois apresentou resultados contraditórios e n o confiáveis. Observou-se queda do pH e aumento da acidez total da manipueira incubada nas condi es estudadas, que pode explicar o comportamento da sobrevivência de Xam em manipueira.

Scientia Agricola , 2000,
Abstract: O presente trabalho teve como objetivo avaliar a sensibilidade in vitro e in vivo de um isolado de Clavibacter michiganensis subsp. michiganensis (Cmm) aos produtos cloridrato de kasugamicina, fulusulfamide e oxitetraciclina. Para o teste in vitro, foram avaliados os halos de inibi o formados ao redor de discos de papel de filtro umedecidos com os produtos, nas concentra es de 0, 1, 10, 100 e 1000 mig mL-1, 24 h após a instala o do ensaio. Quanto à avalia o dos produtos in vivo, dois ensaios foram instalados sob condi es de casa-de-vegeta o, com plantas de tomateiro cultivar ngela Hiper, através da inocula o das plantas por dois métodos: pulveriza o foliar e ferimento no caule. Nos dois ensaios, as plantas foram pulverizadas com os produtos cloridrato de kasugamicina a 0,06 mL L-1, fulusulfamide a 0,025, 0,05 e 0,075 mL L-1 e oxitetraciclina a 0,40 g L-1, duas vezes antes e duas vezes após a inocula o, em intervalos médios de 5-7 dias. Foram avaliados a incidência de folíolos doentes (inocula o foliar) e a severidade dos sintomas nas plantas inoculadas por ferimento no caule. Verificou-se que o isolado de Cmm foi sensível in vitro ao cloridrato de kasugamicina, ao fulusulfamide e à oxitetraciclina, respectivamente a partir das concentra es de 1000, 100 e 10 mig mL-1. Com rela o aos ensaios in vivo, apenas oxitetraciclina propiciou menor incidência de folíolos doentes nas plantas inoculadas através de pulveriza o foliar; nenhum produto teve êxito em controlar a doen a nas plantas inoculadas por ferimento no caule. O fulusulfamide, em todas as concentra es, foi fitotóxico aos folíolos das plantas de tomateiro.
