Investigations carried out for several years have shown that the treatment of rye and wheat crops with an amine salt of 2,4-dichlorophenoxyacetic acid and dialene produces sometimes a decrease in the grain thiamine content of these cereals. Feeding of rye and wheat grains grown with the use of the amine salt of 2,4-dichlorophenoxyacetic acid to growing ratlings has demonstrated that the thiamine content in the liver of ratlings is directly proportional to thiamine supply to their body with food.

The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Spain and co-rapporteur Member State Germany for the pesticide active substance phosphine are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012. The conclusions were reached on the basis of the evaluation of the representative uses of phosphine as a post-harvest indoor insecticide to control insects infesting stored grains (barley, oat, rye, wheat), cacao and coffee beans, tree nuts and oilseeds and dried fruit via gassing application (gas-tight rooms/container).

The variability of the snow mold pathocomplex (the quantitative composition of snow mold fungi) has not been evaluated across different crops or different agrocenoses, and no microbial taxa have been predicted at the whole-microbiome level as potential effective snow mold control agents. Our study aimed to assess the variability of the snow mold pathocomplex in different winter cereal crops (rye, wheat, and triticale) in different agrocenoses following the peak disease progression and to arrange a hierarchical list of microbial taxa predicted to be the main candidates to prevent or, conversely, stimulate the development of snow mold pathogens.

Gluten-free products must not contain more than 20 mg/kg of gluten to be safe for consumption by celiac disease patients. Almost all analytical methods are calibrated to wheat, wheat gluten or gliadin, and there is no rye-specific reference material available. The aim of this study was to assess the effect of the harvest year on rye gluten composition and to generate distinct rye isolates to serve as calibration standards.

Managing deoxynivalenol (DON) risks is crucial for the sustainability of small grain farms. One approach involves profitable utilization of contaminated grain resources, addressing potential losses from food safety concerns. This study explored distillation as a high-value alternative for utilizing DON-contaminated grain.

Background: Fusarium head blight (FHB) is a major disease affecting cereal crops including wheat, barley, rye, oats and maize. Its predominant causal agent is the ascomycete fungus Fusarium graminearum, which infects the spikes and thereby reduces grain yield and quality. The frequency and severity of FHB epidemics has increased in recent years, threatening global food security.
