Studies based on microbial ecology and antagonistic interactions play an important role in the development of new alternative strategies in controlling plant pathogens and are relevant to further biotechnological applications. Antagonistic interactions between the yeasts Candida krusei and Kloeckera apis isolated from rotten pineapple fruits, and two isolates of the pathogenic filamentous fungus Fusarium guttiforme (Syn.: Fusarium subglutinans f. sp. ananas) resistant and susceptible to fungicide benzimidazole were studied in broth culture, and on plate assays. The yeasts significantly reduced Fusarium conidial germination after 24 h of cocultivation in broth culture, and also mycelial growth on plate assays. Slide coculture appeared to show attachment of yeasts to the hyphal surface and also slight morphological abnormalities caused by C. krusei. Filtrates of cocultures of fungi and yeasts inhibited fungal growth, but filtrates of the yeast cultures alone did not, suggesting that the antagonistic action of the yeasts is inducible.
The F. guttiforme isolate sensitive to benzimidazole was most affected by both yeasts in pineapple juice, reaching a maximum of 36.5 % germ tube inhibition. This isolate was also inhibited by yeasts in mycocinogenic plate assay. These results demonstrated that C. krusei and K. apis are effective in inhibiting F. guttiforme growth and that the mode of action is associated with hyperparasitism and mycocinogenic activity. |

The objective of this work was to evaluate the fungi incidence and their control on the seeds of Coffea canephora cv. 'Apoatã' and 'Robusta Tropical-EMCAPER 8151'. The seeds were packed in transparent polyethylene bags and stored for 12 months under refrigeration (4±3°C). A completely randomized experimental design with four replication, using the method of filter paper in Petri dishes. The seed treatments were made by Captan solution, Ridomil solution, Thiabendazole plus Thiram blend and control (no treated seed). The incidence of fungi was measured weekly and after 28 days of incubation, carried out the identification of microorganisms through a microscope. Fusarium sp. and Aspergillus spp. were the two genera of fungi identified infestation of robusta coffee seeds of two cultivars in the storage period of 12 months. The treatment with Thiabendazole+Thiram blend was the most effective for reducing the infestation in seed of cv. 'Apoatã' and 'Robusta Tropical-EMCAPER 8151'.

As sementes foram acondicionadas em sacos transparentes de polietileno e armazenadas por 12 meses sob refrigeração (4±3°C). O delineamento experimental foi inteiramente casualizado, com quatro repetições, utilizando o método do papel filtro em placas de Petri. Os tratamentos de sementes foram feitos com solução de Captan, solução de Ridomil, mistura de Thiabendazol mais Thiram e controle (sem sementes tratadas). A incidência de fungos foi medida semanalmente e após 28 dias de incubação, realizada a identificação dos microrganismos através de microscópio. Fusarium sp. e Aspergillus spp. foram os dois gêneros de fungos identificados infestação de sementes de café robusta de duas cultivares no perÃodo de armazenamento de 12 meses.
