| ABSTRACT Onion’s (Allium cepa) slippery skin caused by Burkholderia gladioli pv. alliicola is one of the bacterial diseases that stand out in producing regions of the Brazilian Northeast. Given the importance and potential threat of this disease, and the absence of resistant varieties, the aim of this study was to evaluate the reaction of onion genotypes to slippery skin and to analyze the tolerance stability of the most promising genotypes to different strains of the bacteria. Nine strains of B. gladioli pv. alliicola were artificially inoculated in onion bulbs cv. Baia Periforme and the three most aggressive strains (CCRMBG39, CCRMBG172 and CCRMBG212) were selected to evaluate the tolerance to the disease. Fifty-eight onion genotypes were challenged with... |

| Avaliou-se o efeito de óleos essenciais e extratos vegetais no controle da podridão mole em alface, bem como, a influência desses produtos nas características físico-químicas desta hortaliça. Nos testes in vitro, discos de papel de filtro foram embebidos em 11 óleos essenciais e 20 extratos vegetais nas concentrações 0,0; 0,25; 0,50; 0,75 e 1% e 0,0; 10, 40, 70 e 100%, respectivamente, e depositados sobre meio de cultura contendo Pectobacterium carotovorum subsp. carotovorum (Pcc A1). Os halos de inibição foram mensurados após 24 e 48 h de incubação. Em casa de vegetação, plantas de alface cv. Veneranda foram tratadas com 11 óleos nas concentrações de 0,5 e 1%, 20 extratos na concentração de 10% e Mycoshield® (3 g L-1), sendo inoculadas com o isolado Pcc... |

| ABSTRACT Bacterial wilt limits tomato production and resistant rootstocks could be important for the integrated management of the disease. Since there is an interaction between local bacterial strains and tomato genotype, this study aimed to evaluate 14 tomato rootstocks to bacterial wilt in the Mata mesoregion of Pernambuco state, Brazil. The rootstocks reaction to two sequevars of Ralstonia solanacearum and two of R. pseudosolanacearum was evaluated in four experiments carried out in the greenhouse using the completely randomized experimental design, with four replications composed of four plants each. Seven genotypes were selected to evaluate the reaction to bacterial wilt as rootstocks grafting in tomato plants ‘Tomini F1’ in a production area with... |
