Systemic induced resistance (SIR) in a plant enhances disease resistance to a broad spectrum of pathogens. Under climate chamber conditions, oxalic acid’s ability to elicit SIR in tomato (Lycopersicon esculentum Mill.) against wilt caused by Fusarium oxysporum f.sp. lycopersici (Fol) was tested with a susceptible cultivar (Danish Export). Oxalic ac...
A series of laboratory experiments were performed to screen the presence of gram negative
bacteria (coliform group) in drinking water to determine its suitability for human consumption and in
clinical, pathological, and ophthalmology purpose. A new medium (Makka medium) with methylene blue
as an indicator which inhibit Gram positive bacteria was de...
A comparative study of water chemistry and phytoplankton composition of four water samples at Suluq Lake was made seasonally during the period from 2005 to 2006. During most of the study period, the water samples were characterized by relatively low values of total alkalinity and total suspended matter, in addition to low nitrogen, phosphorus, sili...
Interaction with animals provide necessary companionship and helps people to live better life by reducing risk of many health problems, improved fitness and act as a source of social enjoyment. In modern society there is a substantial increase in the number of dogs adopted as pet which also raises the concerns regarding the transmission of infectio...
The fungal flora with special attention to Trichoderma in 23 soil samples collected from Al-Jabal Al-Akhdar Region, Libya was studied using different culture media. Trichoderma Selective Medium (TSM), Martin's medium (MT) and Potato Dextrose Agar (PDA) were the superior media for isolating Trichoderma. Martin's medium (MT) and Malt Extract medium (...
Viruses are one of the main hazards for both humans and animals. They enter in the living body and redirect body’s metabolism to produce large copies of their genome and proteins. Diseases caused by these viruses are difficult to tackle with the help of currently available antiviral drugs. So the aim of this study was to explore the plants with rep...
Recently, there has been increasing interest in Ficus deltoidea (Moracea) due to its chemical composition and the potential health benefits. The leaves of the plant have been suggested to have potential antidiabetic effects. Inhibition of carbohydrate-hydrolysing enzymes, such as -glucosidase and -amylase is one of the therapeutic approaches to con...
Bark extracts of Bauhinia purpurea were phytochemically analyzed and evaluated for antimicrobial and antioxidant activities. The phytochemical analysis of the bark extracts revealed the presence of alkaloids, flavonoids, steroids, saponins, triterpenes and carbohydrates. While most of them were present in methanolic and aqueous extracts, one or a f...
Medicinal herbs were the primary health care agent over the many centuries before development of modern medicine. The fact that herbal medicines have been employed for such a long time does not guarantee their efficacy and safety. On that basis, an attempt was made on efficacy and safety studies of a well known medicinal herb in Malaysia, Ficus del...
The capacity of a non-pathogenic strain of Fusarium oxysporum (IMI 386351) to control fusarium wilt of a susceptible tomato (Lycopersicon esculentum Mill.) cultivar Danish Export caused by Fusarium oxysporum f. sp. lycopersici was examined along with the biology of that strain, including its phylogenetics. Based on the morphological and the molecul...
Conidia of two isolates of Trichoderma harzianum (T7 and T8) (Rifai) were formulated to make alginate pellets with or without xylan or CMC as a food-base material. The formulations were compared for their ability of in vitro carboxymethycellulase and xylanase production with free fungal spore suspensions. Conidia entrapped in alginate with or witho...
The effect of Aluminium (80µM) on seedlings of two rice cultivars varying in their sensitivity to aluminium was investigated with different pH conditions ranging from 7 to 4 and with different age groups from 4 to 28 days. With decrease in pH of the culture solution below 5, Aluminium caused reduction in plant growth, high level of aluminium accumu...
Shoot tips of finger millet (Eleusine coracana) were inoculated on to Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of auxins [(2,4-D, NAA), cytokinins (KN, BAP) and other growth promoters (Proline, Tiyptophan, casein enzyme hydrozylate(CEH)]. The higher degree of embryogenic callus formation observed w...
Isolation and identification of fungi associated with food grains were carried out on 20 food grains
including cereals: wheat, barley, corn, sorghum, fenugreek, millet; legumes: pea, peanut, chickpea, faba bean,
kidney bean, cowpea, red and green lentil; oil-producing seeds, walnut, almond, hazelnut, sesame, pistachio
and two animal feeds: diet and...
Under climate chamber conditions, suppression of tomato wilt disease caused by Fusarium oxysporum f. sp. lycopersici (FOL) was obtained by spraying a suspension of Phytophthora cryptogea (Pc) zoospores on the green parts of two tomato cultivars, Danish Export (susceptible) and Elin F1 (moderately resistant). Direct competitive or antagonistic inter...
Two pathogenic special forms (f. sp.) of the Fusarium oxysporum species complex f. sp. lycopersici (Fol) and f. sp. radicis-lycopersici (Forl) are morphologically indistinguishable. Although they are pathogenic to the same host genus Lycopersicon (tomato), and infect the same tomato cultivar, they form distinct diseases; Fol causes wilt and Forl ca...
Summary. In a search of bacterial biological control agents, 50 bacterial isolates collected from roots of wild plants
in northern Sweden were tested in vivo for suppression of wilt of tomato caused by Fusarium oxysporum f. sp.
lycopersici. Tomato plants were sown in 10-cm-diam. pots and after 21 d 7 ml of bacterial suspension (ca. 2x109 cfu ml-1)...
A Fusarium species (Fsp) non-pathogenic to tomato (Lycopersicon esculentum Mill.) was shown, using in vitro experiments, to be an effective inhibitor of the tomato wilt pathogen Fusarium oxysporum f. sp. lycopersici (FOL). Induction of resistance to FOL in tomato plants was performed with Fsp, salicylic acid (Sa) and Phytophthora cryptogea (Pc) und...
