1. Antifungal potential of essential oils from two varieties of Citrus sinensis (lima orange and bahia navel orange) in postharvest control of Rhizopus stolonifer (Ehrenb.: Fr.) Vuill.
Abstract Brazil, the world’s largest citros producer, yields around 19 million tons per year and exports most part of its production as orange juice. Essential oils (EOs) extracted from leaves, fruit and flowers of many species of the genus Citrus have been widely used as the result of their promising bioactivities. The fungus Rhizopus stolonifer (Ehrenb.)

2. Óleos essenciais no controle de Botrytis cinerea: influência na qualidade pós-colheita de uvas ‘Rubi’
Resumo Para que ocorra o controle de doenças na pós-colheita de uvas, são utilizados agroquímicos que, apesar de eficientes, podem causar problemas à saúde humana. Neste sentido, o presente trabalho tem o objetivo de verificar o potencial dos compostos voláteis presentes no óleo essencial de pitanga (OEP), guaçatonga (OEG) e melaleuca (OEM) no contr

3. Detection and epidemiological progress of quiescent avocado diseases
RESUMO: Um dos grandes problemas na comercialização de abacates é a incidência de doenças pós-colheita, principalmente a antracnose (Colletotrichum spp.) e as podridões pedunculares (Lasiodiplodia theobromae, Fusicoccum aesculi e Neofusicoccum spp.). Em função da carência de informações epidemiológicas sobre esses patossistemas, objetivou-se es

4. Post-harvest characterization of ‘Prata’ banana cultivar grown under different nitrogen and potassium fertilization
Resumo Existem diversas cultivares de banana resistentes à Sigatoka-negra e Fusariose da bananeira; porém, pela falta de informações referentes às características de pós-colheita, muitas são rejeitadas no mercado. A adubação nitrogenada e potássica poderia auxiliar na melhoria das características sensoriais da banana madura; no entanto, pouco se

5. Identificação e seleção de espécies de Trichoderma spp. endofíticos de bromélias de restingas como agentes de biocontrole da fusariose em frutos de abacaxi
RESUMO Uma das doenças fúngicas de grande importância que ataca a cultura do abacaxizeiro é a fusariose, causado pelo fungo Fusarium guttiforme. A utilização do Trichoderma spp, que são fungos habitantes do solo e de ocorrência natural na forma endofítica em bromélias, ainda não foi estudada visando o biocontrole da gomose do abacaxizeiro. O traba

6. Production and Optimization of Killer Toxin in Debaryomyces hansenii Strains
ABSTRACT Postharvest diseases of fruits and vegetables result in critical losses of production in worldwide. The losses often are caused by fungi and nowadays, most fungal pathogens are controlled by several strategies such as the use of fungicides. However, most of the fungicides are chemical-based compounds and are dangerous to human health and the nature.

7. Conyza canadensis: Green Extraction Method of Bioactive Compounds and Evaluation of Their Antifungal Activity
Synthetic fungicides are a common treatment for post-harvest diseases in fruits, although demand is increasing for alternatives such as biopesticides. The aim of this work was to investigate the presence of naturally occurring antifungal compounds in Brazilian specimens of the weed Conyza canadensis. Two compounds [(4Z)-lachnophyllum lactone and (4Z,8Z)-matr

8. Temporal progress and spatial patterns of quiescent diseases in guava influenced by sanitation practices
ABSTRACT: Postharvest diseases are a major problem in guava crops as the symptoms normally appear during fruit ripening. This study aimed to detect and characterize the temporal dynamics and spatial patterns of the most important guava diseases in orchards with and without removal of crop residues as a sanitation practice. The experiment was conducted in an

9. Effects of the protective, curative, and eradicative applications of chitosan against Penicillium expansum in apples
Abstract Apple is one of the most important temperate fruit to Brazil economy, and the use of synthetic chemicals has been the main method for reducing postharvest diseases, such as the blue mold, caused by Penicillium expansum. This work intends to evaluate the practical utilization of chitosan for blue mold control. For this purpose, fruits were treated in

11. Incidence of postharvest diseases on 'Kumagai' and 'Pedro Sato' guavas at wholesale markets in Brazil
The time after harvest is characterized by physiological changes in the fruit that favor the occurrence of postharvest diseases, which are often observed only after sale. As a result, the damage resulting from the action of quiescent pathogens can be underestimated. From November to April of the years 2009/2010 and 2010/2011, a survey was conducted to quanti

12. Postharvest rot and mummification of strawberry fruits caused by Neofusicoccum parvum and N. kwambonambiense in Brazil
In addition to the rots that are commonly found on strawberries, a new disease was found in 7% of stored fruits during a survey of strawberry diseases at the postharvest stage. Koch's postulates were satisfied, and the fungi were identified as Neofusicoccum kwambonambiense and N. parvum based on morphology and phylogenetic analysis of the internal transcribe
