Sanitary quality of maize (corn) & Mycotoxins

Research Programmes

Growing maize (corn)

In the field, attack on maize (corn) by a strain of toxigenic Fusarium is a necessary but insufficient condition for the production of mycotoxins.

Many factors interact with one another, such as environmental conditions, the nature of the fungal strain, genetic characteristics and the condition of the plant.

To complement programmes carried out since 2001 with the aim of creating Fusarium-tolerant hybrids Maïsadour Semences has been carrying out extensive research in real conditions on the agronomical criteria influencing the development of fusariosis and the production of Fusarium toxins.

The many references obtained and accurate analysis of these enables practical recommandations to be drawn up for corn-growing practice.


An extensive network of farmers' plots

Each year, the network of the "traceability" study includes over 400 farmers' plots carefully chosen to represent a wide variety of situations:


Observations carried out

Each plot is described in precise detail and numerous abservations carried out:


Fusariosis readings and analysis of harvested grains

When harvested, the ears are subjected to a visual appraisal of their sanitary condition (Ear Visual). A sample of grains is taken in order to carry out microbiological analyses (taking into account the number of fusarium-infected grains) and dosage of mycotoxins (Fumonisins B1, B2 and B3, deoxynivalenol or DON, and Zearalenone or ZON).

Organisation of the research programmes

The programmes are organised around criteria governing the sanitary conditions in the field

Which fungi are likely to synthesize mycotoxins in maize (corn) grains and which toxins are they likely to produce? Are there answers to these questions? Please consult the introductory section:
