| Sclerotinia sclerotiorum, the causal agent of white mold, is a polyphagous pathogen with a large number of plant hosts, and that can survival for many years in the soil. Alternative methods are necessary to its control, such as homeopathy. This work aimed to verify the antimicrobial activity of homeopathic drugs against S. sclerotiorum. Two assays were conducted: the first one using Nosode of S. sclerotiorum, and the second with Sulphur, both at 0, 6, 12, 24, 36 and 48 CH (hahnemanian centesimal dilution), and distillated water as control treatment. The dilution 0 CH was the hydro alcoholic solution with ethanol 30%. The number of sclerotia and the mycelial growth were evaluated in vitro. None of the drugs reduced the mycelial growth of S. sclerotiorum,... |

| - Female root-knot nematode can present compounds able to activate defense mechanisms in the vegetable. With this end, the chromatographic technique is based on the purification of molecules such as proteins, glycoproteins, nucleic acids and polysaccharides, which may present eliciting characteristics. The aim of this paper was to determine the elicitors purification methodology, from phytopathogenic nematodes, by gel filtration chromatography (GFC). Nematodes females of Meloidogyne incognita and Meloidogyne javanica were extracted, macerated, and subsequently subjected to gel filtration chromatography. For the M. incognita five protein peaks and seven glucosidic peaks, with molecular masses ranging from 8.80 to 285.95 KDa and from 65.09 to 7.47 µg glucose... |

| Charcoal Rot is a disease that occurs in a large number of plant species and besides not being economically controlled by fungicides no genetic resistance has been found. Associated with this controlling problem, there is also a growing awareness of the proper handling of pesticides or of the search for new and environmentally safer technologies for handling of plant diseases. Therefore this study aimed to examine in vitro the potential of different isolates of Trichoderma sp for biological control of Macrophomina phaseolina. Seventeen different isolates of Trichoderma sp. were used, in two different tests: direct confrontation with the pathogen and production of volatile compounds by the antagonist. In the experimental conditions the different isolates of... |

| The induced resistance eficiency in the control of phytopathogens is recognized, however little is known about its interference on non-target microrganisms. The present study aims to verify the induction of peroxidase activity by the use of acibenzolar-S-methyl (ASM), mannanoligosaccharide (MOS) and Bacillus cereus inductor in the control of spot blotch wheat disease and its interference on the non-target microrganism A. brasilense. The experiment was conduced under green house growing. The experimental design was made in randomized block design in a factorial schema 4 x 2 x 2, with 4 replications. The first factor "Resistance Inductors" was constituted by ASM, MOS, B. cereus inductors and water (control). The second factor "Pathogen" was constituted by... |

| The identification of molecules present in plants by chromatographic techniques such as HPLC, can bring promising alternative to the control of plant diseases, since brassicas have glucosinolates, which act in plant defense. The objective of this work was to verify the presence of allyl isothiocyanate by HPLC (High Performance Liquid Chromatography Reverse Phase), using different methods of extraction. The plant material was leaves of Crambe abyssinica, dried at 45 °C for 48 h. The extraction methods used consisted of 200 mg L-1 of plant material for each method: infusion, aqueous solution, and cetonic, hydroalcoholic, methanol, hexane and chloroform solutions. The identification and quantification were by HPLC on C18 column UV at 244 nm. The experiment... |

| The aim of the work was to evaluate the growth and productivity of lettuce cultivars cultivated in greenhouse with and without thermo-reflective screens. The experiment was conducted in greenhouse in Assis Chateaubriand, Paraná State. The experimental design was in a randomized block design with six replications and treatments arranged in a 2 x 4 factorial. The first factor consisted of culture environments (with and without thermo-reflective screens 50%) and the second of four cultivars of lettuce (Itapuã, Paola, Vera and Verônica). Five samples were performed weekly for evaluation of dry matter and leaf area used to obtain the absolute and relative growth rates, net assimilation rates, leaf area ratio and specific leaf area. At the last evaluation were... |

| The objective of this work was to evaluate the effect of environment on the productive performance of arugula in different row spacings and plant spacing. The experiment was conducted in the spring, summer 2011 and in the autumn and winter 2012. The experiment design was a randomized complete block design with four replications in a 3x2 factorial design. The first factor consisted to the row spacings (0.20; 0.25 and 0.30 m) and the second to the plant spacings (0.05 and 0.10 m). The plant height and diameter, leaf number, leaf area and total leaf fresh matter and productivity were evaluated. The data were subjected to variance analysis and the average were compared by Tukey test (p<0.05). In the spring and in the plant spacing of 0.05m were verified... |
