“…For example, the use of sodium bicarbonate incorporated into a wax coating with C. oleophila (2 Â 10 8 cfu/ ml) is a commercially acceptable alternative to chemicals for post-harvest control of anthracnose of papaya during storage (Gamagae et al, 2004). Biological control of post-harvest diseases of bananas with natural plant compounds (Anthony et al, 2004;Demerutis et al, in press;Ranasinghe et al, 2002Ranasinghe et al, , 2005Thangavelu et al, 2004), antioxidants (Khan et al, 2001), and inorganic salts alone (Alvindia et al, 2004) or in combination with surfactant (Alvindia and Natsuaki, 2007) has also been studied. The combination of such compounds with the yeast treatment could also enable an improvement of the biological control.…”

The antagonistic activity of two yeast strains (Pichia anomala (E.C. Hansen) Kurtzman, strain K and Candida oleophila Montrocher, strain O) against the parasitic complex responsible for banana crown rot was evaluated. The strains were applied at three different concentrations (10 6 , 10 7 , 10 8 cfu/ml) and their efficacy tested in vivo on three separate fungi (Colletotrichum musae (Berk. & Curt.) Arx, Fusarium moniliforme Sheldon, and Cephalosporium sp.) and on a parasitic complex formed by association of these three fungi. At the concentrations used C. musae appeared to be the most pathogenic. The complex showed intermediate aggressiveness between C. musae and both other fungi.Statistically significant antagonistic effects were observed on C. musae, F. moniliforme, and the fungal complex. The highest protection level (54.4%) was observed with strain O added at 10 8 cfu/ml on crowns previously inoculated with the fungal complex. The level was lower when the fungi were inoculated separately.Furthermore, the antagonistic effect was strongly reinforced when strain O at 10 8 cfu/ml was applied 24 h before fungal complex inoculation (59.9%), as compared to its application 15 min (24.3%) or 3 h (27.3%) after fungal complex inoculation. Bananas showed increased susceptibility to the fungal complex from March to June, and this influenced the level of protection by yeast, which decreased over the same period. A strict negative correlation (R 2 = 0.83) was highlighted between susceptibility of banana to crown rot and protection provided by yeast.

“…The Jatropha leaf extract was effective in controlling the fungal pathogens Sclerotium sp. and Colletotrichum musae which, causes azolla and anthracnose diseases, respectively (Thangavelu et al, 2004). Furthermore, the latex of Jatropha contains an alkaloid known as 'Jatrophine' which is used as a hemostatic and wound dressing (Esimone et al, 2009) and is said to be efficacious in treating scabies, wasp and bee stings, treat bleeding gums, toothache, anti-inflammation, eczema and ringworm (de-Feo, 1989;Van-den et al, 1995).…”

Abstract:The study on antibacterial and antifungal efficacy of leaf and seed extract and seed oil of Jatropha curcas reveals that the inhibition zones ranged from 7 to 22 mm for antibacterial and from 10 to 20 mm for antifungal activity. Among all extracts tested, seed extract showed significant activity while leaf extract showed intermediate activity against gram-positive bacteria. In case of gram-negative bacteria, seed extract and seed oil has shown some moderate activity whereas, no activity was observed in leaf extract. In case of fungal cultures, among all test extracts only seed extract showed significant activity against Mucor and Tilletia fungus, while in case of Rhizopus no activity was observed against all test extracts. These results indicated the possibility of using Jatropha extract and seed oil for medicinal uses and natural food preservation.

“…Therefore recent efforts have been directed towards plant extracts and the development of secondary metabolites as potentially useful products for commercial biomolecules with fungicidal properties 10–12. For example, Jatropha curcas extract was found to inhibit the mycelial growth of Colletotrichum musae , a fungus that causes anthracnose disease in bananas,13 and it was also effective in controlling the fungal pathogen Sclerotium sp., which causes Azolla disease 14. The essential oil, methanol extract and derived fractions of Metasequoia glyptostroboides showed great potential for antifungal activity against Fusarium oxysporum, Fusarium solani and other fungi 15, 16.…”
