Genetic variation for resistance to ear rots and mycotoxins contamination in early European maize inbred lines
Ear rots caused by Fusarium spp. are a major concern in many maize (Zea mays L.)–growing regions of the world. Our objectives were (i) to evaluate a set of European maize inbreds for resistance to ear rots and mycotoxin concentrations, (ii) to estimate variance components and heritabilities, and (iii) to compute correlations among resistance traits. Forty-two inbreds were evaluated for resistance ...

The impact of using GM insect resistant maize in Europe since 1998
Genetically Modified (GM) insect resistant (Bt) maize crops have been grown commercially in the European Union (EU) since 1998, and in 2006, there were plantings in seven EU member states. This paper reviews the specific economic impacts on yield and farm income as well as the environmental impact in respect of insecticide usage (where data exists). The analysis shows that there have been ...

An analysis of Bt corn's benefits and risks for national and regional policymakers considering Bt corn adoption
This paper examines important factors for policymakers to consider when making a decision to adopt Bt corn planting and commercialisation, by analysing the market, environmental, and health benefits and risks of Bt corn as well as current regulatory policies that may affect trade. Bt corn, genetically modified to produce a pesticidal protein, has benefits that include improved yield, decreased ...

Evaluation of maize inbred lines for resistance to aspergillus and fusarium ear rot and mycotoxin accumulation
Mycotoxin contamination in corn (Zea mays L.) grain is a worldwide threat to safety of both human food and animal feed. A select group of inbred corn lines was evaluated in field trials for ear rot caused by Aspergillus flavus and Fusarium verticillioides and mycotoxin accumulation in grain. Our goal was to identify lines resistant to both fungi. In separate tests, 20 inbred lines were inoculated ...

Multi-residue mycotoxin analysis of dry distillers grains
Distillers grains (DG) are the still residues after the ethanol has been collected. Approximately 90% of US production is used in domestic animal feed. Any Mycotoxins present in the fresh corn can be concentrated by a factor of three. Contamination can also occur during storage. This raises concern about the potential animal and human health hazards from the use of Mycotoxincontaminated ...

How to store feed pellet
During the rainy season, the air humidity is relatively high. If the feed is not stored properly, it is easy to become moldy and deteriorate. Various nutrients in the moldy feed are destroyed, the nutritional quality of the feed decreases, and even its utilization value is completely lost. After livestock and poultry eat moldy and rotten feed, toxins will accumulate in the animal's body, causing ...

What are the most common forms of Cannabis testing?
With cannabis now legal, either for medicinal or recreational use, in a number of countries around the world, the scientific community is increasingly focussing on its quality control and ensuring it is safe for use. There isn't just one form of testing which can be carried out to determine the 'quality' of cannabis to indicate if it is safe for human use. Everything from pesticides to heavy ...

Analysis of Aflatoxin B1, B2, G1, and G2 in Corn Meal, Wheat Meal, and Raw Peanut Paste Matrices
The Supel Tox AflaZea SPE cartridge was used to demonstrate the cleanup of corn meal, wheat meal, and raw peanut paste matrices prior to the analysis of Aflatoxin B1, B2, G1, and G2. In the procedure, corn meal, wheat meal, and raw peanut paste extracts were spiked with Aflatoxin Standard Mix (Product No. 34036) and run through the Supel Tox AflaZea SPE cartridges. The eluate was collected and ...

Multi-residue mycotoxin analysis single run analysis of deoxynivalenol, aflatoxins, ochratoxin a, zearalenone and fumonisin by HPLC and post-column derivatization
Although Aspergillus (Aflatoxins, Ochratoxin A) are generally associated with peanuts and Fusarium (Deoxynivalenol , Zearalenone) with wheat, these fungi and those that produce other toxins are not host selective and so can cross plant species. This situation is complicated by the fact that the microscopic mold may not be visible to the naked eye. Also, when infected grains are processed, any ...
