“…In Adamawa State, Benue State, Plateau State (Jos), and its surroundings, different fungal species are linked to the yam tuber rot illness. Seven fungal species, including Aspergillus flavus, Asperillus niger, Penicillium citrinum, Penicillium echinulatum, Penicillium purpurogenum, Trichoderma spp., and Trichophyton spp., were among the microorganisms that were isolated for this investigation (Table I) This is consistent with the findings of Shiriki et al (2015Shiriki et al ( , 2019 and Anwadike, 2019 who noted the presence of some of the above-mentioned species, including Aspergillus niger. Ajayi and Olorundare (2014) reported in their research that Aspergillus niger is the most prevalent fungal species with 50% occurrence.…”

This research on isolation and identification of yam rot pathogen fungi from North central Nigeria was carried out to investigate some fungal species associated with yam rot using white yams (Dioscorea rotundata) obtained from Adamawa State, Benue State and Plateau State (Jos) Nigeria. Seven fungi species which cause yam rot were isolated during this study, namely: Aspergillus flavus, Aspergillus niger, Penicillium citrinum, Penicillium echinulatum, Penicilum purpurogenum, Trichoderma spp and Trichophyton spp. Trichoderma yunnanense strain RCBBR_GA1 OP8008361 was identified molecularly. Pathogenicity test carried out confirmed these organisms as the pathological agent of the rot. A. niger statistically has the highest frequency of occurrence (100%). The least encountered fungal species were the P. citrinum (16.6%), P. purpurogenum (33.3%) and Trichophyton spp (33.3). Percentage growth inihibition of A. flavus, A. niger, P. citrinum, P. echinulatum, P. purpurogenum, Trichoderma spp and Trichophyton spp was carried out and they showed varying degree of inhibition. However, Trichopyton spp shows the highest growth of inhibition at 96 hours (41.4%) and 120 hours (73.7%). Trichoderma exhibited the highest control of the isolates (80 mm). Trichoderma inhibited mycelia extension growth of A. flavus (25 mm), A. niger (25 mm), P. citrinum (23 mm), P. echinulatum (23 mm), P. purpurogenum (24 mm) and Trichopyton spp (22 mm) at 96 hours. The result shows that Trichoderma was able to inhibit the growth of the pathogenic fungi, which are associated with yam rot. Fungal isolates from yam rot were examined morphologically and microscopically and the nature of rot was varied. It is recommended that enzymes from Trichoderma should be extracted and applied for reduction of microbial rot of yam tubers.

“…In this respect, the extracts of garlic and galls had the second and third ranks. However, plant extracts were efficiently used to control the growth of many pathogenic fungi by Kumar et al (2006), Chavada and Chaudhari (2015), Beena et al (2017), Devi andDevi (2017), Miya andShamim (2017), Sarkhosh et al (2018) and Shiriki et al (2019). Camila et al, 2018 tested a different aqueous plant extracts such as the clove extract, they found clove extract effects on the germination and initial development of lettuce seeds were observed, also the effect of clove extract affected on the mycelial growth of the fungus Cercospora longissima (isolated from lettuce plants) were evaluated.…”

Pestalotiopsis mangiferae the causal organism of Mango fruits black spot, was highly isolated from three governorates in Egypt. Plant extracts of Clove, Camphor, Oleander, Gall, and Garlic, also some essential oils such as clove, mint, garlic, and camphor were tested on the inhibition, growth, and sporulation of Pestalotiopsis mangifera both under laboratory and field conditions. Under laboratory condition, clove plant extracts suppressed the growth of Pestalotiopsis mangiferae at all tested concentration (10, 15 and 20%). The extracts of garlic and galls had the second and third ranks, in this respect. All tested plant oils reduced the growth of Pestalotiopsis mangiferae significantly in comparison with control. Mint oil followed by camphor on had the best efficiency in reducing the fungal growth. Under field condition application of either galls and/or clove oil and clove extracts (5%) gave the best result. Moreover, the average number of healthy fruits per tree recorded 35 and 34, respectively, in response to the application of galls and clove plant extracts. Also, the Shelf-life period of mango fruit; both artificially inoculated with Pestalotiopsis mangiferae or not; was increased in response to the application of either plant extracts and/or plant oil; significantly.

Plant-based (Green) synthesis of Copper nanoparticles is of much interest to researchers currently because of its important applications in various fields of biotechnology. In this study, the production of copper nanoparticles (CuNPs) utilizing an ethanolic extract of Catharanthus roseus (L.) and Abutilon indicum (L.) leaves extract (CALE) and assess the therapeutical use of these nanoparticles. Preliminary phytochemical analysis was done by using this ethanolic crude extract of the combined plant. The phytochemical tests showed positive results for the phytochemicals alkaloids, phenols, tannins, terpenoids, and phytosterols. The leaf extract was used for the synthesis of copper nanoparticles and in the reduction and capping of the combined leaf extract CuNPs, it was discovered that the bioactive phytoconstituents condensed tannins, played a crucial role by the reduction of copper ions was identified by the change in color from blue to light green. SEM image showed the morphology and size of the nanoparticles and their binding ability with the combined leaf extracts. The spherical biogenic combined leaf extracts of CuNP’s were measured to have a size between 5 and 25 nm by Scanning Electron Microscopy (SEM) examination, Ultraviolet-Visible spectroscopy (UV-Vis) showed maximum wavelength at 224nm and XRD showed three strong peaks for its crystallinity and maximum was observed at 2063.0. From their characterization of synthesized CuNPs anti-microbial and anti-inflammatory methods were assessed. The samples showed different diameters of zone of inhibition at different concentrations by using Ampicillin as positive control. The synthesized nanoparticles showed a concentration-dependent anti-inflammatory activity, and the protection percentage increased with an increase in the concentration of the samples.
