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 chemical treatment evaluation in the field to control post-harvest fruit anthracnose (Colletotrichum gloeosporioides) requires a suitable disease incidence assessment on harvested papaya (Carica papaya) fruits. The minimum number of papaya fruit harvests was determined for valid treatment comparison in field trials for anthracnose chemical control. Repeatability analysis was done using previously published data. The coefficient determination (R2) estimate range, using four methods, and based on means of 12 assessment times, was 92.58 < R2 < 94.45%. The number of assessment times required for R2=90% varied from seven to nine. The R2 values of 85.1 < R2 < 91.3% estimated by ANOVA suggested that any seven successive assessment times were sufficient for treatment comparison.
Estudos de controle químico da antracnose (Colletotrichum gloeosporioides) em mamoeiro (Carica papaya), no campo, requerem avaliação da intensidade da doença em frutos após a colheita. Determinou-se o número mínimo de épocas de avaliação (colheitas) necessárias para comparação adequada de tratamentos. A análise de repetibilidade foi aplicada a dados previamente publicados. Estimativas usando quatro métodos resultaram em coeficientes de determinação (R2), baseados na média de 12 épocas de avaliações, de 92,58 < R2 < 94,45% e o número de épocas de avaliações requerido para obter R2 = 90%, variou de sete a nove. O R2 estimado por ANOVA indicou que quaisquer sete épocas de avaliação sucessivas foram suficientes para comparação entre tratamentos, apresentando 85,1 < R2 < 91,3%.
