“…A diagrammatic scale, with scores from one to seven, was used to evaluate SCO (Reid et al, 2009). For PER, the proportion of ears with ER symptoms was considered concerning the total number of ears of the plot.…”

“…Recently, the incidence and severity of these ER diseases have increased in Brazil, especially those caused by the fungi Diplodia maydis and Fusarium verticillioides, which can lead to losses of around 50% in grain yield due to a considerable reduction in ear weight (Reid et al, 2009). Besides, these diseases hurt grain quality because of the production of mycotoxins, substances that are highly noxious to birds and mammals.…”

ABSTRACT. Plant breeding strategies are constantly refined to increase efficiency during the selection process. Consequently, the aims of this study were to examine genetic control and efficiency of selection based on the per se performance of maize lines and based on hybrid performance in reaction to white spot, common rust, and ear rot diseases in maize breeding programs. We also aimed to examine the relationship between the per se performance of the lines and the single hybrids for resistance to these diseases. To do so, we evaluated the reaction to these diseases in 106 lines and 661 hybrids in different locations in Brazil. Subsequently, the relative importance of the additive and non-additive genetic effects on expression of these traits, the association between the parameters considered upon carrying out the selection in these generations, and gain from selection were estimated. The results indicated that additive effects predominate for resistance to white spot and ear rot diseases, whereas for common rust, dominance effects predominate. However, evaluating the hybrids through diallel analysis was effective in selection for resistance to these diseases. The diseases and the generations evaluated were interrelated; the increase in the level of resistance had a more significant correlated response when selection was directed by the reaction to white spot, and there was a greater genetic similarity between the parameters considered in selection directed by hybrid performance.

“…However, these pathogens should not be neglected since the resistance of a species cannot be extended to the others. That is, resistance to an isolated pure from one species can not result in cross-resistance to a Fusarium population in commercial corn fields (Reid et al, 2009). The conditions for fungal growth and therefore mycotoxin production depends on environmental factors and erroneous parameters, such as agricultural production without technical and preventive measures, inadequate drying, handling, packaging, storage, and transport conditions that may promote fungal growth .…”

In the animal feed industry, an ever growing increase in quality has been observed, but the main feature of a food is related to its security because the contamination poses a risk to animal health. The problems caused by fungal colonization is the significant loss of food quality, because even those who do not produce mycotoxins cause losses in the nutritional quality. Researches show that the most important Fumonisins are the mycotoxins found in corn, particularly when cultivated in warmer regions, produced by the fungi Fusarium verticillioides and F. proliferatum. Equine leukoencephalomalacia is a disease caused by ingestion of mycotoxin produced by the fungus F. verticillioides. Those infective mycotoxins are fumonisin (B1, B2, A1 and A2), having the B1 type as the most common and the most severe. The animals contamination occurs by ingestion of corn and its by-products in food that are contaminated by the fungus. This review addresses the importance of fungal contamination of the genus Fusarium by the production of fumonisin in horse feed and its relation to leukoencephalomalacia.

“…One of the early inbreds (Reid et al, 2003) is a common resistant check in many programmes. Some of these inbreds have resistance to multiple diseases (Reid et al, 2009). The availability of these inbreds has allowed researchers to explore QTLs, underlying mechanisms and inheritance of resistance (Mesterhazy et al, 2012).…”

This paper summarises workshop discussions at the 5 th international MYCORED meeting in Ottawa, Canada ( June 2012) with over 200 participants representing academics, government and industry scientists, government officials and farming organisations (present in roughly equal proportions) from 27 countries. Workshops centred on how mycotoxins in food and feed affect value chains and trade in the region covered by the North American Free Trade Agreement. Crops are contaminated by one or more of five important mycotoxins in parts of Canada and the United States every year, and when contaminated food and feed are consumed in amounts above tolerable limits, human and animal health are at risk. Economic loss from such contamination includes reduced crop yield, grain quality, animal productivity and loss of domestic and export markets. A systematic effort by grain producers, primary, transfer, and terminal elevators, millers and food and feed processers is required to manage these contaminants along the value chain. Workshops discussed lessons learned from investments in plant genetics, fungal genomics, toxicology, analytical and sampling science, management strategies along the food and feed value chains and methods to ameliorate the effects of toxins in grain on animal production and on reducing the impact of mycotoxins on population health in developing countries. These discussions were used to develop a set of priorities and recommendations.
