Lead
AgroSustain développe et met sur le marché des solutions naturelles pour arrêter et prévenir le développement de moisissures sur les fruits et légumes frais.
Lay summary

USD 60 milliards de pertes de fruits et légumes en post-récolte sont causés par des champignons pathogènes qui, en outre, peuvent produire des métabolites toxiques pour l'homme, par exemple l'aflatoxine - cancérigène toxique produit par les espèces du genre Aspergillus. A ce jour, il n'existe sur le marché aucun traitement efficace, économique et naturel contre les moisissures.

 

AgroSustain est une spin-off de l'Université de Lausanne qui a identifié un grand nombre de composés antifongiques d'origine végétale. AgroShelf+, le premier produit en cours de développement, est un traitement efficace, inspiré des plantes, contre une large gamme d'agents pathogènes fongiques d'importance agronomique (plus de 20 espèces de champignons pathogènes). L'objectif d'AgroShelf+ est de prolonger d'au moins une semaine la durée de conservation des cultures infectées par des moisissures.

 

L'application du produit AgroShelf+ générera les avantages suivants pour les détaillants et distributeurs en alimentation :

1.  Réduction des pertes alimentaires après récolte de 80%

2.  Haute qualité alimentaire sans résidus chimiques

3.  Satisfaction des consommateurs

Abstract

Fatty acids (FA) are known to be one of the major storage forms of carbon in living organisms, which are precursors for some plant hormones such as jasmonate (JA) and major building compounds of the membrane bilayer. During my PHD, I identified a new role of fatty acids in induction of plant resistance to B. cinerea. It is a nectrotrophic fungal pathogen that affects a broad range of cultivated and ornamental plants and causes serious agricultural loss each year (Jarwis, 1977). In this work, I will develop a new biofungicide based on the fungitoxic molecule identified from the Arabidopsis plants deficient in fatty acids. Two cultivars of Vitis vinifera (wine grape), Fragaria × ananassa (strawberry) and Solanum lycopersicum (tomato), displaying different susceptibility to B. cinerea will be used as model plants for biofungicide optimisations. Product concentration will be based on the results of fungicide sensitivity assays. Pre-formulation trials will be assessed against the two other major fungal pathogens of grapevine, i.e. the ectophytic powdery mildew (Erysiphe necator) and downy mildew (Plasmopora viticola). The second part of this project will be to identify other potential fungitoxic compounds from the plants that were shown to have B. cinerea resistance and bringing them to the market by developing efficient and low energy cost biological fungicides for farmers needs. The outcome of this project will be development of the new environmental friendly fungicide that potentially can lead to strong reduction in yield lost due to B. cinerea that could be applied in the agricultural fields and launching a start up “AgroSustain” at the end of Bridge funding.
