Summary

Contamination of grain with Mycotoxins by Fusarium spp, Aspergillus spp. and Peni¬cillium spp. is a serious problem in conventional and organic cereal production. Based on a literature survey of in total 183 German and international papers (original articles, review articles, conference abstracts and contributions to textbooks) the following agronomical factors were judged to be of major importance for a possible contamina¬tion of cereals with mycotoxins: growing conditions, choice of variety, pre crop, soil tillage intensity, use of fungicides, weed control, intensity of fertilisation and storing conditions. Due to the fact that conventional compared to organic farming in general shows narrower crop rotations with a higher number of risky pre crops as well as a higher nitrogen fertilisation in combination with the use of growth regulators and a less intensive soil tillage, the authors judge the risk of a potential contamination of cereals with mycotoxins in Germany to be lower in organic than in conventional farming.
