Fusarium head blight (FHB) is an important disease of wheat and causes significant economic and yield losses. The principal pathogen associated with FHB in Manitoba is Gibberella zeae (Schwein.) Petch (anamorph = Fusarium graminearum Schwabe). Trichoderma harzianum Rifai is a well-known biocontrol agent of many plant pathogens. The extracts from 11 T. harzianum isolates and cellfree filtrates w...

The anaerobic decomposition of plant biomass is an important aspect of global organic carbon cycling. While the anaerobic metabolism of cellulose and hemicelluloses to methane and carbon dioxide are well-understood, evidence for the initial stages of lignin decomposition is fragmentary. The objective of this study was to look for evidence of chemical transformations of lignin in woody tissues [...

Aflatoxins (AFs) are cancerous secondary metabolites produced primarily by Aspergillus flavus and Aspergillus parasiticus in agricultural foodstuff such as peanuts, maize grains, cereals, and animal feeds. Food and Agricultural organization (FAO) estimated that as much as 25% of the world’s agricultural commodities are contaminated with mycotoxins, leading to significant economic losses. Moreov...

The objective of the study was to determine the quality and fatty acid profiles of mutton cuts purchased from rural and urban localities in South Africa. Five hundred and ten samples were collected in four seasons from both rural and urban shops and butcheries. Samples were immediately transported to the laboratory in cooler boxes with ice where the following physico-chemical characteristics of...

Wheat is one of the most important food staff in consumption pattern of each country. More than 50 percent of energy is provided by bread in the developing countries. The aim of this study was measuring wheat losses during pre-harvest and harvest stages in Chaharmahal and Bakhtiari province of Iran in year 2013. Wheat losses at harvest stages were measured to wheat varieties in 2 levels of Omid...

Food and beverage authentication is the process by which food or beverages are verified as complying with their label descriptions (Winterhalter, 2007). A common way to deal with an authentication process is to measure attributes, such as, groups of chemical compounds on samples of food, and then use these as input for a classification method. In many applications there may be several types of ...

Post-harvest diseases ,caused by Penicillium digitatum and Penicillium italicum, lead to considerable losses of citrus fruits. Several research studies have focused on biological properties and antimicrobial activity of essential oils (EO) extracted from the Medicinal and Aromatic Plants (MAP). The main objective of this paper is to study the antifungal effects of two essential oils of the fami...

Honeybee disappearance is one of the major environmental and economic challenges this century has to face. The ecto-parasitic mite Varroa destructor represents one of the main causes of the worldwide beehive losses. Although halting mite transmission among beehives is of primary importance to save honeybee colonies from further decline, the natural route used by mites to abandon a collapsing co...

Predictions of surface water exposure to "down-the-drain" chemicals are presented which employ grid-based spatially-referenced data on average monthly runoff, population density, country-specific per capita domestic water and substance use rates and sewage treatment provision. Water and chemical load are routed through the landscape using flow directions derived from digital elevation data, acc...

Pseudomonas savastanoi pv. savastanoi (Gardan et al., 1992) (hereafter Psv, according to Vivian & Mansfield (1993)) is the causal agent of olive knot disease. It is considered one of the most serious diseases affecting olive trees (Olea europaea L.) in most olive growing regions worldwide and mainly in Mediterranean countries, where this crop has been growing for centuries. The disease can lead...
