One of the main diseases occurring in clonal nurseries of Eucalyptus spp. is powdery mildew caused by the fungus Oidium eucalypti. This work evaluated the efficiency of biological products based on Trichoderma spp. and Bacillus spp. applied as preventive and curative treatments for the control of Oidium eucalypti in clonal seedlings of E. benthamii Maiden et Cambage. Treatments were: Trichoderma harzianum (THP), T. atroviride (TAI), T. harzianum (THE), Trichoderma spp. (TTA), Bacillus spp. (BNE), Sulfur (KUM), Difenoconazol (SCO) and distilled water (AD). Treatments were applied preventively by spraying seven days before inoculation of the pathogen, and in curatively, ten days after inoculation. Weekly evaluations of the incidence and severity of the disease were done. The analyzed variables were: Disease Index (ID) and Incidence (I), calculating the area under the disease curve (AUDPC) for each treatment. The results pointed BNE (Bacillus spp.) and TAI (isolate T. atroviride) as effective preventive treatments and BNE (Bacillus spp.), applied curatively for the control of O. eucalypti in E. benthamii seedlings, proving that treatments based on biological products may be effective for controlling eucalyptus powdery mildew in clonal nurseries.

The present study investigated the effects of exposure of bamboo–plastic composites to three aggressive fungi species on mass loss values. Polyvinyl chloride was used as the synthetic matrix of the composite. Three mixing combinations were used for bamboo–polymer composites, namely 40/60, 50/50, and 60/40. The injection-molded process was employed to produce the composites. Specimens were prepared according to modified European standard specifications (EN-113) to be exposed to white-, brown-, and soft-rot fungi each month for 4 months. The results indicated that the soft-rot fungus ( Chaetomium globosum) generally caused higher mass losses in all bamboo/plastic combination ratios. Brown- and soft-rot fungi demonstrated different mass losses on different combination ratios. However, the white-rot fungus ( Trametes versicolor) caused nearly the same mass losses on all three combination ratios. Moreover, T. versicolor was highly significant with respect to mass loss and moisture content. It can therefore be concluded that the T. versicolor has a different decay metabolism when compared to the brown- and soft-rot fungus used in this study.

Diseases caused by fungi associated with adverse weather conditions are one of the main causes of decreases in sugarcane production. This study aimed to develop a protocol for a fast identification of Phaeocytostroma sacchari, which is the causal agent of bark rot in sugarcane. The reference sequences of three DNA regions of P. sacchari, namely internal transcribed spacer, ribosomal large subunit and translation elongation factor 1-alpha (TEFl-α), were analyzed with specific primers design. The specific primers generated that aligned in their entirety with P. sacchari were selected and synthesized. Polymerase chain reaction (PCR) assays were performed to confirm the primer specificity, using P. sacchari isolates and 10 species of other genera. Two sets of primers that amplify the TEF-1α region (PsFl/Psfl and PsF2/PsR2) showed a high specificity and sensitivity in detecting P. sacchari using conventional PCR, what will allow large-scale surveys of this pathogen in sugarcane crops.
