“…It was observed that changes that occurred in the ultrastructure of this pathogen corroborate findings by several researchers in other pathosystems, as reported in (ROZWALKA et al, 2010;RASOOLI et al 2006;TIAN et al, 2012;AVIS et al, 2009). Scanning and transmission electron microscopy examinations reveal ultrastructural alterations in several compartments of the cell, such as plasma membrane, cytoplasm (swelling, shrivelling, vacuolations, leakage) and nucleus (SOYLU et al, 2006;SANTORO et al, 2007;TYAGI;MALIK, 2010, DAN et al, 2010.…”

Pseudocercospora griseola, the etiologic agent of angular leaf spot of common bean (Phaseolus vulgaris), is an important disease in all bean-producing regions worldwide and may cause extremely high yield losses. The control of this disease is made more difficult by the pathogen's genetic variability and the inefficiency of fungicides. In this study, of 26 essential oils tested at different concentrations, 25 demonstrated efficiency in affecting the germination of strains 63-31 and 63-63 of the pathogen, reaching inhibition levels of between 80% and 100%. Cymbopogon citratus and Cymbopogon martinii inhibited conidia germination at all concentrations; Eugenia caryophyllata, Cinnamomum sp., Thymus vulgaris, Matricaria recutita, Cordia verbenacea, Origanum vulgare, Cymbopogon nardus, at 0.1 and 0.5%; and Zingiber officinale, Mentha arvensis, Chamaecyparis pisifera, Lavandula officinalis, Ocimum basilicum, Pimpinella anisum, Ocimum selloi, Baccharis dracunculifolia, Laurus nobilis, Citrus sinensis, Melaleuca alternifolia and Eucalyptus globulus, at 0.5%. The main constituents identified were cinnamaldehyde in Cinnamomum sp.; eugenol in E. caryophyllata; trans-β-farnesene in M. recutita; pulegone in C. verbenacea; thymol in T. vulgaris; geranial and neral in C. citratus, and geraniol in C. martini. Through transmission electron microscopy (TEM), it was verified that C. citratus, C. martini and E. caryophyllata presented direct fungitoxic action on P. griseola, causing severe damage to the cellular ultrastructure of the conidia, invalidating germination. These results indicated that essential oils are a promising alternative strategy for the control of angular leaf spot in bean, representing less risk to human health and the environment.

“…Previous studies have focused on the inhibitory effect of essential oils against fungal growth in vitro, and some have been tested in vivo to control postharvest diseases. 11,25 In this study, citronella oil was systematically investigated in vitro and in vivo on cherry tomato to demonstrate the antifungal inhibition activity against A. alternata. Citronella oil showed pronounced antifungal efficacy against A. alternata mycelial growth in vitro.…”

“…Furthermore, essential oils extracted from plants are considered to be non‐phytotoxic agents, suggesting that the majority of them are safe for consumers, and also have a low risk of pathogens developing resistance to them . Previous studies have proved the activities of certain essential oils against fungal pathogens to control postharvest diseases in vitro and in vivo . The antimicrobial properties of the oils were attributed to the presence of mono‐ and sesquiterpenes, mono‐ and sesquiterpene hydrocarbons and phenolic compounds such as thymol, carvarol, citral, trans ‐2‐decenal and p ‐cymene …”
