Endophytic colonization of five Trichoderma species and their effects on growth of a Eucalyptus hybrid.

The study aimed to evaluate the effectiveness of endophytic colonization via leaf and root inoculation of five Trichoderma species in a Eucalyptus hybrid, as well as the effects of inoculation on plant growth. The experimental design was completely randomized in a 6 × 2 factorial scheme. Plant growth was evaluated during the experimental period at three different times: 20 days after inoculation (d.

Aromatic compounds from the endophytic fungus and their allelochemical property using OSMAC strategy.

Endophytic fungi are biodiverse and alternative source of bioactive compounds, due their different abilities of genetic expression and alteration of biosynthetic pathway when submitted to different culture conditions. The metabolic profile of three different crude extracts (A, B and C), obtained from the endophytic fungus , were evaluated by HPLC and H NMR. Antioxidant and allelochemical activity were also evaluated.

Essential Oil of Cymbopogon citratus on the Control of the Curvularia Leaf Spot Disease on Maize.

The Leaf Spot is becoming more common due to the culture expansion and the low resistance of the cultivated genotypes in tropical regions. Thus, the objective was to evaluate the fungitoxicity of the essential oil of upon the phytopathogen , causative agent of the Leaf Spot. There was realized pathogenicity tests of in maize plants, phytotoxicity of the essential oil of and gas chromatography attached, germination tests of the conidia, and of in vitro inhibition of .
