“…Similar to this is the findings of Okigbo R. N. and Ogbonnaya who reported the efficacy of A. melegueta extract in the control A. niger, F. oxysporum and Botrydiplodia theobromae causing rot in yam [22]. The effectiveness of methanol extracts of the two plants over the aqueous extracts supported the report of Adejumo, that methanolic extracts of botanicals possess high antimicrobial properties [23]. This is likely to be due to the solubility of the active compounds in methanol.…”

An investigation was carried out to examine the effect of some seed borne fungi on seed germination and seedling emergence of soybean. A total of five fungi species comprising four genera namely Aspergillus flavus, Aspergillus niger, Fusarium oxysporum. Penicillium chrysogenum and Colletotrichum sp were isolated from the tested seeds. The effects of the mycelial suspension of the isolated fungi on percentage seed germination and seedling emergence was studied. Ten seeds were soaked in mycelial suspension of each fungus for 1hour before placing on Petri-dishes and sowing in bags containing 3 kg sterilized soil in triplicates. It was observed from the study that Penicillium chrysogenum had the highest inhibitory effect on seed germination while Aspergillus niger had no effect on seed germination. Also, the result showed that all the isolated fungi had a significant effect (p<0.05) on length of radicle with A. flavus recording the least length of radicle (2.10 cm) as compared with the control (4.75 cm). Fusarium oxysporum, Penicillium chrysogenum and A. flavus significantly reduced shoot length. While all the isolated fungi had significant differences at p<0.05 on root length with P. chrysogenum recording the least root length (5.15 cm) as compared with 10.13 cm observed on the control. The efficacy of both the aqueous and methanol extracts of Aframomum melegueta and Petiveria alliacea was assessed against the mycelial growth of the isolated fungi at 10, 20 and 30% concentration. The methanol extract of both plants most especially that of Aframomum melegueta performed better in inhibiting the radial growth of Aspergillus flavus, Aspergillus niger, Fusarium oxysporum and Colletotrichum sp.

“…These two fungi produce ochratoxin A and fumonisin mycotoxins (Bui-klimke and Wu, 2015; Adejumo and Langenkämper, 2012), and have been associated with pathologies such as nephrotoxicity, hepatotoxicity and renal tumors in a variety of animals (Buitimea et al, 2013). In addition, according to recently reported data, the economic losses of food production due to mycotoxins are estimated between hundreds of millions and billions of pesos annually (Pinotti et al, 2016).…”

The present study aimed to identify the phytochemicals of methanolic extract from Baccharis glutinosa (chilca) roots (MEBg) and to evaluate its antifungal activity on two major fungal pathogens of agricultural importance. The antifungal activity was evaluated by inhibition halo, minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC) and % sporulation against A. ochraceus and F. moniliforme. As-1 a preliminary test, inhibition halo was tested using 1, 10, 100 and 270 mg ml of MEBg. Different concentrations of MEBg were applied for MIC and MFC tests. Ketoconazole was used as positive control. The treatments were applied in triplicate. The phytochemical compounds of MEBg were determined by GC-MS analysis. The MEBg produced an inhibition zone of 2 to 4 mm in the inhibition halo test, with concentrations-1 of 100 and 270 mg ml for A. ochraceus and F. moniliforme, respectively. Reduction in % sporulation above-1 50 was shown in concentrations over 8 mg ml. MEBg were reported to exhibit antifungal activities against A.-1 ochraceus and F. moniliforme with the MIC values ranging from 2 to 5.6 mg•ml and the MFC from 12 to 15-1 mg ml. GC-MS analysis of Chilca extracts revealed that the most abundant metabolites were furfural compounds and organic acids. The most abundant furfural compounds were 5-(hydroxymethyl) furan-2carbaldehyde (38.59%), furan-2-carbaldehyde (4.103%) and 5-methylfuran-2-carbaldehyde (2.1%). The MEBg revealed efficient antifungal activity, likely due to the presence of bioactive compounds, which could be used as an alternative for biological control of pathogenic fungi in maize and coffee crops.

“…A. melegueta (Aligator pepper) is another plant popularly used as a food spices and as a traditional medicine for treating various ailments in Nigeria and other parts of the world. There are a lot of scientific work on the activities of A. melegueta such as antinociceptive www.gjournals.org 211 (Oloke, 1992;Okigbo and Ogbonnaya, 2006;Umukoro and Ashorobi, 2007), antifungal activity (Ejechietal., 1997;Adejumo and Langenkämper, 2011), for controlling insect pests (Ewete et al, 1996;Ejechi et al, 1997;Oparaeke et al, 2005;Ukeh et al, 2009) and as a flavouring agent in food (Ajaiyeoba and Ekundayo, 1999). Piper guineense commonly referred to as African black pepper or Ashanti pepper belongs to the family Piperaceae and is known with different vernacular names in Nigeria which include 'Uziza' in Igbo, and 'Iyere' in Yoruba.…”

Laboratory study was conducted to determine the efficacy of six plant extracts Gmelina arborea Roxb (Verbenaceae) leaf, Aframomum melegueta [Roskoe] K. Schum. Zingiber officinale Rosc., Morinda lucida (L.) (Rubiaceae), Moringa oleifera Lam. (Moringaceae) (seed and leaf) and Garcinia kola Heckel (Guttiferae) on the management of African wood termite under ambient temperature and relative humidity (30 0 c and 72%). Twenty termites were introduced into a covered container and treated with three levels (0.0 g, 0.5 g, 1.0 g) of the various plant extracts. The experiment was laid out in a completely randomised design (CRD) and replicated four times with factorial arrangement of treatments. Mortality was recorded at 12, 24, 36, 48, 60, 72, 84 and 96 hours exposure periods respectively. A. melegueta and G. kola were effective at 60 hours of exposure for 0.5g rate of application recoding 95% mortality while Z. officinale, M. oleifera recorded 100% mortality after 84 hours of exposure. At 1.0 g rate of application, M. oleifera seed and A. melegueta were efficacious after 12 hours, however, M. oleifera recorded 95% mortality after 60 hours and 100 % at 72 hours while A. melegueta and M. lucida recorded 95 and 75 % mortality at 48 hours of exposures respectively. No mortality was recorded untreated experiment. Conclusively, A. melegueta, M. lucida and M. oleifera seed and leaf can be used in the control of wood termite due to higher mortality recorded on application and as a substitute for synthetic insecticides.
