| 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 continuous use of pesticides protecting plants from diseases can result in several damages due the environmental pollution and food residues. Thus, it is necessary the search for new plant diseases control technology. The objective of this study was to evaluate the in vitro antimicrobial activity against Alternaria solani and Xanthomonas vesicatoria and the control of early blight and bacterial spot on tomato plants, using stable formulation, as soluble powder, from Pycnoporus sanguineus. To determine the shelf life, the soluble powder was kept at 40 oC during 0, 60, 120 and 180 days and assayed with five concentrations (0, 50, 100, 150 and 200 mg L-1). When the shelf life and the best concentrations were defined, it was evaluated the time-interval of... |

| In the scenario of renewable energy, Brazil has an important role, especially the biodiesel production chain that is growing, but its feasibility depends on the source material still adequate. An alternative source material is the crambe (Crambe abyssinica Hochst), but little is known about this culture. Thus was determined the survey of the diseases that may limit production in western Paraná. The disease survey was conducted by the sanity of two fonts of seeds and the field survey of diseased plants. In the two fonts of seed were evaluated incidence of fungi and bacteria, and in the commercial seed, bacteria were predominant in 20% of the seeds, and in seed obtained directly from the producer, there was highest incidence of fungi, predominantly... |

| In order to seek new measures to protect plants against diseases, alternative agriculture through the use of medicinal plants has been much studied. The objective of this study was to evaluate the effect of rosemary extract, cloves, cinnamon, garlic and guaco, under different sterilization methods (water bath at 65 ºC for 1 hour, water bath at 85 ºC for 1 hour; Autoclaving at 110 ° C for 20 minutes and autoclaving at 120 ° C for 20 minutes) in the mycelial growth of M. phaseolina. The AACCM was found for each form of sterilization in the extracts used. The extracts of rosemary, garlic and clove have an antifungal potential against M. phaseolina verified for the method of sterilization autoclaving at 120 ºC for 20 minutes, water bath at 65 ºC and 85 ºC for... |

| Nematodes, especially Meloidogyne sp., are hard to control due their aggressiveness and the lack of products registered for this purpose. Therefore, the objective of this work was to evaluate the in vitro nematicide / nematostatic potential of 1%, 5% and 10% of aqueous extract of Rosmarinus officinalis (rosemary) against M. incognita. The experiment was conducted in the Nematology Laboratory of Unioeste, Marechal Cândido Rondon, Paraná State. The experimental design was completely randomized, with four treatments, using three concentrations of aqueous extract of rosemary and water as control treatment, with five replicates each. Motility and mortality of second stage juveniles (J2) were evaluated after 24 and 48 h, respectively. The rosemary extract showed... |

| - 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... |

| New products for incorporation in the seeds have been available annually as bioactivators plant and rootinge reinforcers that are used to increase the productive potential of plants through changes in plant metabolism and nutritional supplementation. Therefore, the study sought to evaluate the effects of rooting reinforcers and biatovador in health, productivity and development of wheat. The study consisted of two experiments. The first was conducted in the field about a eutrophic Oxisol in a 4x2 factorial with four seed treatments (water, thiamethoxam, rooting reinforcers, rooting reinforcers+thiamethoxam) and two conditions of application of fungicides (with and without aerial spraying). The second trial occurred in a greenhouse measuring biometric data... |

| A cultura do feijoeiro tem uma grande importância econômica para o Brasil, maior produtor e consumidor mundial dessa leguminosa. Porém, a produção brasileira do feijão é afetada principalmente por dois patógenos (Pseudocercospora griseola e Xanthomonas axonopodis pv. Phaseoli), necessitando pesquisas voltadas a qualidade de sementes, utilizando extratos no controle de doenças. Diante do exposto, objetivou-se com o presente trabalho avaliar a germinação, desenvolvimento de plântula, teor de proteína e teor de minerais das sementes colhidas de plantas tratadas com extratos secos de alecrim e cúrcuma. O experimento foi realizado a campo, em delineamento experimental de blocos ao acaso, utilizando 1, 2 e 3 aplicações de cúrcuma e alecrim na concentração de 50... |

| The Mycosphaerella spot is one of the main foliar diseases of strawberry, degrating great leaf regions and reducing the photosynthetic area. Its control is mainly by the use of chemical fungicides, but, due the increasing demand for food free of pesticide, alternative control methods have been researched, such as biological control. This work aimed to evaluate the effect on strawberry plants, treated with the biological control agents Bacillus cereus, Saccharomyces boulardii and Saccharomyces cerevisiae, in the severity of Mycosphaerella fragariae, productivity and in the activity of β-1.3 glucanases, peroxidases and chitinases enzymes. It was verified that S. cerevisiae and B. cereus treatments were similar to fungicide for disease control. However, even... |
