Endophytic entomopathogenic fungi are being explored for the management of phytophagous insect pests. The effects Beauveria bassiana (Hypocreales) inoculation grape plants on infestation level P. ficus, tissue nutrient contents, and growth volatile constituents potted were assessed. Grapevine individually inoculated with a suspension 1 × 108 conidia mL−1 B. by drenching before experimentally infesting each them thirty adult females ficus. At four weeks post-treatment, fungus was re-isolated...
Diabetes mellitus (DM) is one of the most dangerous metabolic diseases with a high rate mortality worldwide. It well known that insulin resistance and deficiency in production from pancreatic β-cells are main characteristics DM. Due to detrimental side effects current treatment, there considerable need develop new effective antidiabetic drugs, especially alpha-glucosidase alpha-amylase inhibitors lesser adverse effects. These be directly involved delay carbohydrate digestion, resulting...
Shortage in insulin secretion or degradation of produced is the principal characteristic metabolic disorder diabetes mellitus (DM). However, because current medications for treatment DM have many detrimental side effects, it necessary to develop more effective antidiabetic drugs with minimal effects. Alpha-glucosidase and alpha-amylase inhibitors are directly implicated delay carbohydrate digestion. Pharmacologically, these could be targeted reduction glucose absorption rate and,...
This study aimed to investigate the effect of entomopathogenic fungus Beauveria bassiana on growth and ability Tulbaghia violacea synthesise nanoparticles volatile compounds. was inoculated by drenching with different concentrations B. conidial (0 mL−1, 1 × 106 107, 108 conidia mL−1) colonization plant tissue in fungal treatments evaluated. A UV–VIS spectrometer (SPECTROstar nano) used determine presence while constituents plants were analysed chromatography-mass spectrometry. Polyphenols,...
In this study we examined the anti-tick properties of essential oil Tagetes minuta L. (Asteraceae: Asterales) against Hyalomma rufipes ticks. We obtained T. by hydro-distillation a combination fresh flowers, leaves and soft stems, analysed these using gas chromatography (GC) chromatography-linked mass spectrometry (GC-MS). The had high percentage monoterpenes major compounds identified were cis-ocimene (28.5%), beta-ocimene (16.83%) 3-methyl-2-(2-methyl-2-butenyl)-furan (11.94%). adults...
The endophytic plant-fungi symbiotic relationship can be explored to improve cultivation of targeted medicinal plant species. objective this study was assess the effects chive (Allium schoenoprasum) in growth medium inoculated with entomopathogenic fungus, Beauveria bassiana (Hypocreales). Twelve replicates seedlings were exposed B. inoculum formulated at concentrations 0, 1 × 105, 104 and 103 conidia mL-1 a completely randomized design. We assessed parameters, such as leaf number height...
Heavy metal toxicity is a major threat to the health of both humans and ecosystems. Toxic levels heavy metals in food crops, such as grapes, can have devastating effects on plant market value produce. Two important factors that may influence prevalence grapevines are seasonal change farming practices. The objectives this study were (i) conduct detailed pioneer screening soils grapevine leaf tissues selected wine farms (ii) season tissues. Soil samples collected from demarcated areas...
Endophytic entomopathogens have growth promoting, nutrient fortifying, and anti-insect properties that could improve the yield quality of lettuce (Lactuca sativa L.). Lactuca is a vegetable crop with high demand; however, it susceptible to aphid infestations. This study’s objectives were assess pathogenicity Beauveria bassiana (strain: SM3) (Bals.) Vuil. (Hypocreales) against Myzus persicae Sulzer, tissue colonization by conidia B. bassiana, as well effects fungal inoculation on growth,...
A consortium of microbial community was used for the treatment acid mine drainage wastewater laden with sulphate and heavy metals. The treated in an anaerobic continuously stirred tank bioreactor. activity increased pH from 5.6 to 6.5, improved removal up 85% initial concentration 8080 mg SO42−/L a continuous mode, following enrichment 21 d. maximum metal percentage observed Cd (98%), Al (97%), Mn (95%), Pb (94%), Sr (94%) Cu (91%). showed synergy between strictly facultative Firmicutes sp.,...
The wild population of Siphonochilus aethiopicus (Zingiberaceae) is being eroded due to several pharmacological benefits and the hidden economy credited its ethnobotanical uses in Southern Africa. This has called for adoption sustainable ways cultivating species without compromising bioactive constituents. In this study, compost tea was brewed applied at different dosages potted S. enhance growth quality, phytochemical content, elemental compositions. Treatments comprised 0.25, 0.50, 0.75...
Background: Traditional medicine plays a major role in the primary health care of many people living rural areas. South Africa is a
 home to over 30,000 species higher plants and 3,000 these have been found be used traditional across the
 country. African medicinal are decreasing at an alarming rate as result exploitation. Today plants
 face extinction but detailed information lacking. The purpose this paper was review current proposed cultivation strategies
 that could...
The overexploitation of wild plants for medicinal uses and conventional agricultural farming methods, which use high amounts water, fertilizers, pesticides, have had devastating environmental consequences. This study aimed to evaluate the prospects using aquaponics hydroponics as alternative approaches soil cultivation by comparing crop yields, secondary metabolite contents, antifungal activities ethanol extracts Helichrysum odoratissimum (L.) Sweet, a widely used plant species in Southern...
The submontane forests in the Congo Basin have not been studied sufficiently terms of floristic diversity, biomass, and geographic distribution. region's lack resources rugged terrain are among barriers to sampling biodiversity. This study focuses on two understudied forest areas, Bakossi National Park (BNP) Mt. Nlonako (MN), which form part continental Cameroon Mountains believed high species diversity endemism. However, significant gaps exist biodiversity data across Mountains. is first...
The toxic effects of the extracts Allium sativum (Garlic) were evaluated against adults Hyalomma marginatum rufipes and Rhipicephalus pulchellus using three types (Types A, B C) contact toxicity bioassays. A. bulbs extracted with acetone, ethanol dichloromethane (DCM) solvents. Among these solvents, it is DCM extract that appears to have anti-tick activity. In Type A bioassay, demonstrated a high acaricidal bioactivity H. m. 100% ticks killed in less than an hour, persisted second day. weak...
Optimization of the quality and quantity medicinal materials during cultivation could improve value plants. Light intensity water availability affect physiological processes growth Tulbaghia violacea L. (Alliaceae) bulbs leaves are widely used traditionally in southern Africa for treatments many ailments. The interactive effects light watering regime on plant growth, nutrient uptake antifungal activity T. were evaluated current study. Seedlings grown hydroponically under two shading levels...

Studying the mechanisms through which endophytic fungi confer protection to host plants against parasites will contribute toward elucidating fungi−plant−pathogen relationship. In this study, we evaluated effects of Beauveria bassiana on antioxidant activity, oxidative stress, and growth tomatoes infected with fusarium wilt pathogen, Fusarium oxysporum f. sp. lycopersici (FOL). Tomato seedlings were inoculated B. conidia then contaminated FOL experimentally. Four treatments (Control [T1],...
