“…As reported by several authors, causal agents of FER include Fusarium species belonging to FFSC that are considered weak pathogens of maize but are also able to produce mycotoxins (Jardine & Leslie, ). Although the spread and severity of FER is usually low to moderate in northern Italy, due to differences in virulence of FFSC populations, fumonisin contamination of kernels can be very high (Berardo et al ., ; Torelli et al ., ).…”

“…Fumonisin B 1 contamination in maize grain is of concern because of its causal role in equine leukoencephalomalacia, porcine pulmonary oedema, liver and renal carcinogenicity in laboratory rodents and possibly even human carcinogenicity (Shephard et al ., ). Differences in levels of fumonisin B 1 detected in northern Italian‐grown maize can be due to several factors such as weather variables and specific cultural practices (Torelli et al ., ).…”

The influence of flavonoids in maize pericarp on fusarium ear rot symptoms and fumonisin accumulation under field conditions

et al. 2014

Breeding efforts have been undertaken to increase resistance of maize to fusarium ear rot (FER) and to fumonisin accumulation. Flavonoids in the pericarp of the kernels are considered particularly able to reduce the fumonisin accumulation. The aim of this 2-year field study was to assess the effect of flavonoids on FER symptoms and fumonisin contamination in maize kernels using two isogenic hybrids, one providing pigmentation in the pericarp (P1-rr) and the other without it (P1-wr). FER incidence (FERi), FER severity (FERs), the incidence of infections caused by Fusarium spp. in symptomless kernels (FF) and fumonisin contamination (FUM) were assessed in both hybrids. Significant differences between the two hybrids were detected mainly in 2012 trials where P1-rr showed lower FERi (P < 0Á01), FF (P < 0Á05) and FUM (P < 0Á1) than P1-wr. Site, characterized by local temperature and precipitation, played a relevant role in modelling all the measured variables, as its effect was highly significant in both years, whether they were considered individually or altogether. The interaction of hybrid with location was a significant (P < 0Á001) source of variation only for FF. FF, together with FERi, was also significantly (P < 0Á001) influenced by the interaction of hybrid with year. In general, FUM was more influenced by year and location parameters, such as temperatures during late ripening, than by flavonoid presence in kernel pericarp. The results indicate that flavonoid pigments alone may not be an important component in the resistance of maize to fumonisin accumulation.

“…high temperature during flowering) has been acknowledged, environmental and agricultural conditions may had different effects on F. verticillioides infection and fumonisin contamination in different crop areas depending on many other environmental conditions (local weather, insect species and pressure, amount of inoculum in the environment, geographical location, etc.) (Battilani et al, 2008;Maiorano et al, 2009a;Schjøth et al, 2009;Torelli et al, 2012). Therefore, recommended guidelines to reduce fumonisin contamination could be effective in a general way but might not have the same importance in all the environments.…”

In northwestern Spain, where weather is rainy and mild throughout the year, Fusarium verticillioides is the most prevalent fungus in kernels and a significant risk of fumonisin contamination has been exposed. In this study, detailed information about environmental and maize genotypic factors affecting F. verticillioides infection, fungal growth and fumonisin content in maize kernels was obtained in order to establish control points to reduce fumonisin contamination. Evaluations were conducted in a total of 36 environments and factorial regression analyses were performed to determine the contribution of each factor to variability among environments, genotypes, and genotype × environment interactions for F. verticillioides infection, fungal growth and fumonisin content. Flowering and kernel drying were the most critical periods throughout the growing season for F. verticillioides infection and fumonisin contamination. Around flowering, wetter and cooler conditions limited F. verticillioides infection and growth, and high temperatures increased fumonisin contents. During kernel drying, increased damaged kernels favored fungal growth, and higher ear damage by corn borers and hard rainfall favored fumonisin accumulation. Later planting dates and especially earlier harvest dates reduced the risk of fumonisin contamination, possibly due to reduced incidence of insects and accumulation of rainfall during the kernel drying period. The use of maize varieties resistant to Sitotroga cerealella, with good husk coverage and non-excessive pericarp thickness could also be useful to reduce fumonisin contamination of maize kernels.

“…Numerous studies have confirmed the presence of fumonisins in plant material contaminated with their producers, vast majority was focused on maize [16,17,18,19]. However, rice and sorghum are also often infected with Fusaria belonging to the Gibberella fujikuroi species complex: F. fujikuroi , F. proliferatum , F. verticillioides and F. andiyazi [20,21].…”

Fusarium proliferatum and F. verticillioides are considered as minor pathogens of pea (Pisum sativum L.). Both species can survive in seed material without visible disease symptoms, but still contaminating it with fumonisins. Two populations of pea-derived F. proliferatum and F. verticillioides strains were subjected to FUM1 sequence divergence analysis, forming a distinct group when compared to the collection strains originating from different host species. Furthermore, the mycotoxigenic abilities of those strains were evaluated on the basis of in planta and in vitro fumonisin biosynthesis. No differences were observed in fumonisin B (FB) levels measured in pea seeds (maximum level reached 1.5 μg g−1); however, in rice cultures, the majority of F. proliferatum genotypes produced higher amounts of FB1–FB3 than F. verticillioides strains.

The influence of local factors on the prediction of fumonisin contamination in maize

Abstract: This is the first time that an artificial neural network has been used to predict fumonisin accumulation in maize: the prediction has been shown to have the potential for the development of a new approach for the rapid cataloging of grain lots.
