Ear rots caused by different Fusarium spp. are one of the most dangerous food and feed safety challenges in maize production. At present, the majority of the inbreds and hybrids are susceptible. Gibberella and Fusarium ear rots (caused by Fusarium graminearum and Fusarium verticillioides, respectively) are the two main diseases, but more than 10 further Fusarium spp. cause ear rots. Natural infection is initiated by a mixture of the local Fusarium spp

“…Significant correlations were found between the severity of visual symptoms and toxin contamination; generally, they were of medium closeness or were somewhat stronger [ 45 , 46 , 47 , 48 ]. Bolduan et al [ 49 ] calculated an unusually close correlation between ear rot and DON (r = 0.94) with respect to Fusarium ear rot (FER); the conclusion was that toxin analysis may not be necessary.…”

Resistance to toxigenic fungi and their toxins in maize is a highly important research topic, as mean global losses are estimated at about 10% of the yield. Resistance and toxin data of the hybrids are mostly not given, so farmers are not informed about the food safety risks of their grown hybrids. According to the findings aflatoxin regularly occurs at preharvest in Hungary and possibly other countries in the region can be jeopardized. We tested, with an improved methodology (two isolates, three pathogens, and a toxin control), 18 commercial hybrids (2017–2020) for kernel resistance (%), and for toxin contamination separately by two–two isolates of F. graminearum, F. verticillioides (mg/kg), and A. flavus (μg/kg). The preharvest toxin contamination was measured in the controls. Highly significant kernel resistance and toxin content differences were identified between hybrids to the different fungi. Extreme high toxin production was found for each toxic species. Only about 10–15% of the hybrids showed higher resistance to the fungal species tested and lower contamination level of their toxins. The lacking correlations between resistance to different fungi and toxins suggest that resistance to different fungi and response to toxin contamination inherits independently, so a toxin analysis is necessary. For safety risk estimation, separated artificial and natural kernel infection and toxin data are needed against all pathogens. Higher resistance to A. flavus and F. verticillioides stabilizes or improves feed safety in hot and dry summers, balancing the harmful effect of climate changes. Resistance and toxin tests during variety registration is an utmost necessity. The exclusion of susceptible or highly susceptible hybrids from commercial production results in reduced toxin contamination.

“…In regions of moderate climate the infection of maize by Fusarium moulds occurs relatively often, particularly when high rainfall occurs near harvest. Fusarium graminearum and Fusarium culmorum are the most typical species occurring on infected ears (Pomeranz et al., 1990; Téren et al., 1990; Odiemah and Manninger, 1994; Perkowski et al., 1997). Both Fusarium ear rot and stalk rot occur under Hungarian conditions, but in the experiments described in this article, only ear rot was studied in detail.…”

“…Two groups of toxic metabolites, zearalenone and trichothecene derivatives, are present in kernels that are colonized by these species, (Atlin et al., 1983; Scott and King, 1984; Tanaka et al., 1988; Perkowski et al., 1997).…”

It has also been suggested that the possible resistance is connected both with genetic and agronomic factors.…”

Thirty maize hybrids grown in Hungary representing groups FAO 200–299, FAO 400–499 and FAO 500‐were studied in order to obtain information about genotypic resistance to Fusarium moulds. The plants were grown on an experimental farm and were inoculated using the toothpick method with Fusarium graminearum and Fusarium culmorum. In addition maize grain meals were also inoculated with isolates of moulds. Measurements were made of the mould‐covered surface area of the ears 9 weeks after inoculation and of the zearalenone and T2‐toxin content of the inoculated maize meals. Large differences among hybrids were observed for the mould‐covered area of the ear surface (2.00–38.88%), the zearalenone content (4.20–71.20 mg/kg) and the T2‐toxin content (1.60–122.50 mg/kg). Relatively poor correlation (r=0.489) was found between the area of mould covering the ear surface and mycotoxin content of maize. Bearing in mind that the user of feed grain is interested in obtaining a feed with the lowest mycotoxin content, a new method of evaluation of hybrids which uses a toxin–mould index (TMI) was introduced. This index is calculated on the basis of both growth rate of moulds and their toxin‐producing activity. Although a decreasing tendency in resistance of hybrids with a longer growing vegetation period could be observed, resistant genotypes were found in every FAO group, confirming the views that in addition to the influence of duration of the vegetation period on the resistance, genetic factors may also play a significant role.
