ABSTRACT Tomato (Solanum lycopersicum L.) is an economically and nutritionally important crop in Rwanda. However, its production is threatened by the invasive tomato leaf miner (Tuta absoluta Meyrick) since 2015. Options for integrated pest management (IPM) for its control under Rwandan conditions have not been developed. The main objective of this study was to contribute to enhanced tomato productivity and fruit quality in Rwanda through evaluation of entomopathogens and plant extracts as o...
ABSTRACT The present study was conducted in the Laboratory of Plant Pathology at the College of Agricultural Studies.Sudan University of Science and Technology- Shambat. To study the effect of water solvent extracts of Root, Brak and Leave of Mesquite tree ( Prosopis juliflora) and Fungicide REVUS top® on Wilt Branch disease , which is considerate one of most important disease that infectous Mango trees (Mangifera indica), and caausing significant reduction in yield. In present study the pa...
Abstract: Pectinase is a heterogeneous group of enzyme which hydrolyzes pectin. Fungi and actinomycetes have ability to produce a large amount of industrial enzymes. Therefore the present study was undertaken production of pectinolytic enzymes from barley (Hordeum vulgare Von. Bothmer) and wheat (Triticum turgidum L.Von) locally called (Garbu or Qamadi) hulls. Wheat and Barley Hulls samples were collected from homes. Isolation of the fungal species was done on czapek-dox-agar media. Fungal i...
ABSTRACT Current soil management strategies are mainly dependent on inorganic chemical-based fertilizers, which caused a serious threat to human health and environment. The exploitation of beneficial microbes as a biofertilizer has become paramount importance in agriculture sector for their potential role in food safety and sustainable crop production. The eco-friendly approaches inspire a wide range of application of plant growth promoting rhizobacteria (PGPRs), endo- and ectomycorrhizal f...
ABSTRACT Background: A growing population contributes to increasing demand for water. Windhoek’s water supply is based on the use of surface and groundwater. However, all potable water resources within a radius of 500 km have been fully exploited. The rainfall is uncertain and long spells of severe droughts are frequently encountered. There are four main sources of water supply to the central area of Windhoek: surface water obtained from the Von Bach, Swakoppoort and Omatako dams; groundwa...
ABSTRACT Application of Hazard Analysis and Critical Control Point (ITJCCP) of seven species of smoke fish at various locations around Shiroro Lake were evaluated. A Traditional Smoking Kiln and an Improved Traditional Smoking Kiln (control experiment),. This experiment was carried out for a period of sixteen weeks, using six hundred and seventy two(672)samples, sensory evaluation, proximate analysis, microbial identification, heavy metals and and Poly Aromatic Hydrocarbon in thesmoked seven...
Abstract: Soil and water conservation practices in Tigray, northern highlands of Ethiopia are given special emphasis for the restoration of degraded lands. However, information on the effect of SWC practices on the dynamics of soil biota is limited. This study was conducted with the objective of evaluating the effect of two decades long community-based soil and water conservation (CBSWC) practices, viz, stone terraces, exclosure with and without stone terraces which were evaluated against no...
Abstract: Cellulases are complex hydrolytic enzymes working synergistically on the hydrolysis of cellulose to produce smaller sugar components including glucose units. These enzymes have tremendous environmental, industrial and agricultural applications including enhancement of the degradability of lignocellulosic materials. In this research fungal isolates were isolated from forest and compost soil samples and allowed to produce cellulases; and the extent to which the cellulases enhance the...
Abstract: The typical dry bean, Phaseolus vulgaris, is the essential food legume for direct human consumption. They play a significant role in food security and nutrition. Despite their nutritional importance, its production growth rates have declined in Kenya due to diseases, insect pests, plant nutritional deficiencies, and drought. Therefore, this study's main objective was to determine whether there are differences in bean varieties' tolerance to whitefly transmitted viral diseases. The ...
ABSTRACT The basic idea of healthcare facilities which is to make people well is on the verge of being defeated as a result of patients contracting infections while in healthcare settings. Nosocomial infections are infections acquired by patients or healthcare workers while they are in healthcare facilities, including, hospitals, dental offices, nursing homes and doctors’ waiting rooms. Infectious diseases are diseases caused by pathogenic microorganisms such as bacteria, viruses, parasi...
ABSTRACT.In order to access the prevalence and sensitivity pattern of urinary pathogens, 60 midstream urine samples from students of Caritas University were investigated using cultural methods. Samples were examined microscopically and cultured in blood agar and Macckonkey agar. Disk diffusion method was used for antibiotic testing. Of the 60 urine samples 48 yielded significant growth with a prevalence rate of 80%. It was observed that females were more infected than the males with a prevale...
Abstract A study was conducted at the Crop Science Department, University of Ghana, Legon, to isolate,identify and test pathogenecity of fungal isolates causing the reported black sigatoka disease of plantain in Ghana and compare the isolate with that isolated from local tall banana having leaf spots. Field symptoms of plantain and banana were compared and found to be similar. Initial specks indicating infection were minute, reddish-brown and were conspicuous only on the abaxial leaf surfaces...
ABSTRACT This research study is designed to determine the microbial count of Chicken Droppings and Ground Palm kernel shell in which the chicken droppings is used as inoculum on Ground Palm Kernel Shell at Ratio 2: l in which the inoculum size is half of the Ground Palm Kernel Shell. Pollution of the environment due to oil production can be reduced through this study because is aimed at examining the microorganism responsible for the biodegradation that can be achieved in Palm kernel she...
Abstract: Metarhizium anisopliae isolate ICIPE69 is a highly virulent fungal pathogen against several thrips species such as western flower thrips (Frankliniella occidentalis), bean flower thrips (Megalurothrips sjostedti), onion thrips (Thrips tabaci) and others infesting key vegetable crops in Africa. Recently the isolate has been commercialized for pest control under the trade name, Campaign ®. The efficacy of the entomopathogenic fungi is known to be influenced by the prevailing climati...
Abstract: Medicinal plants have been used for centuries to treat diseases. Differences in antimicrobial activities may affected by geographical area and other conditions.This study was carried out to screen the phytochemical composition and antimicrobial activities of leaf,friut and root extracts of U.dioca against pathogenic bacteria and fungus.
