| Eight substrates were evaluated for ex-vitro establishment of Phalaenopsis amabilis seedlings. They were: Fibraflor® (commercial substrate), Turfa Fértil FG2® (commercial substrate), vermiculite, coconut fiber from the pericarp, decomposed pine bark, organic compost, sphagnum and shredded xaxim, in the establishment of seedlings of Phalaenopsis amabilis L., in combination, with and without immersion of the seedlings, after they were removed from the growth flasks, in Manzate 800 at a dosage of 1 g L1. The evaluated parameters were: the sum of the lengths of the two largest leaves, the sum of the lengths of the three largest roots and the percentage of surviving seedlings, evaluated at 190 days after planting. It was observed that there were... |

| Two biological control agents, Bacillus subtilis AP-01 (LarminarTM) and Trichoderma harzianum AP-001 (TrisanTM) alone or/in combination were investigated in controlling three tobacco diseases, including bacterial wilt (Ralstonia solanacearum), damping-off (Pythium aphanidermatum), and frogeye leaf spot (Cercospora nicotiana). Tests were performed in greenhouse by soil sterilization prior to inoculation of the pathogens. Bacterial-wilt and damping off pathogens were drenched first and followed with the biological control agents and for comparison purposes, two chemical fungicides. But for frogeye leaf spot, which is an airborne fungus, a spraying procedure for every treatment including a chemical fungicide was applied instead of drenching. Results showed... |

| ABSTRACT The intensive cultivation of melon, mainly in the Northeast of Brazil, has favored the occurrence of root diseases such as rhizoctonia, caused by the fungus Rhizoctonia solani Kuhn. The use of resistant cultivars is one of the most efficient strategic measures for integrated management of diseases in this crop. It is necessary to use an efficient inoculation method to evaluate rhizoctonia in melon germplasm with the aim of identifying sources of resistance. The objective of this study was to develop an efficient method to inoculate the pathogen to proceed in selection of R. solani resistant melon germplasm. Five experiments were conducted under greenhouse conditions to define the adequate container, growth environment, substrate for inoculum... |

| O condicionamento osmótico e o tratamento de sementes com fungicidas têm apresentado bons resultados na melhoria do vigor e proteção das plântulas contra patógenos associados às sementes e de solo, garantindo assim bom estabelecimento do estande. Objetivou-se com este trabalho, avaliar o efeito do condicionamento osmótico e do tratamento com fungicidas sobre a qualidade fisiológica de sementes de beterraba (Beta vulgaris L.). As sementes foram condicionadas em água, KNO³ (0,34 M) e PEG 6000 (-0,8 MPa). Os tratamentos com fungicidas foram: testemunha (sementes tratadas pela empresa produtora de sementes com Thiran a 0,15%), metalaxil (0,004%), procimidone (0,1%) e metalaxil + procimidone (0,004 + 0,1%). Avaliaram-se as seguintes características: primeira... |
