Objectives

Objectives

Develop cropping systems to prevent and reduce the occurrence of toxigenic fungal species and mycotoxins in maize and small-grain cereals.
Specific objectives are:

  1. Establishment of AFLA EUROPE, AFLA CHINA and AFLA AFRICA preventive systems: select native Aspergillus flavus atoxigenic strains from Europe and China to identify the best candidate biocontrol agents in each country, and to evaluate in Ghana a candidate biocontrol agent containing a mixture of selected strains (Task 4.1);
  2. Development of FUSA_prev: determine in different cropping systems (integrated, conventional and organic) a combination of agronomic practices, e.g. crop rotation, choice of variety, tillage, undersown/cover crops, to reduce Fusarium spp. inoculum and mycotoxins in barley and wheat (Task 4.2);
  3. Advancement of FUSA_bio: select and formulate (an) efficacious fungal and bacterial antagonistic strain(s) to apply onto the preceding crop (endophytic growth and/or crop residues) before maize and wheat to reduce Fusarium inoculum (Task 4.3);
  4. Development of FUSA_res: breed maize for resistance to Fusarium ear rot (FER) and wheat for resistance to Fusarium head blight (FHB) (Task 4.4).
Tasks

Tasks

  • Task 4.1 Biocontrol of Aspergillus flavus to prevent aflatoxin production (UCSC, ZJU, IITA, CNR, IBA, FA, CAAS).
  • Task 4.2 Reduction of Fusarium inoculum and mycotoxins in barley, wheat and maize through agronomic measures (WBF, UGENT, IBA, FA, IPP-CAAS, HAAS, LAAS).
  • Task 4.3 Biological control of F. graminearum with fungal and bacterial antagonists on preceding crop residues (Fusa_bio) (WBF, UGENT, CNR, IBA, FA, HAAS, ZJU)
  • Task 4.4 Breeding for resistance (Fusa_res) (UCSC, CNR, LAAS, IBA, SYNGENTA IT, IPP CAAS, ZJU)
