Plasmopara viticola, the oomycete responsible for downy mildew, is considered to be the most devastating grape pathogen to be known in North America and Europe. This disease was originally observed in the United States in 1834 and has been most abundantly found in the northern and midwestern areas of the United States. Shortly after, the pathogen was introduced in European countries where it played a devastating role in the yield and production of their grapes, and consequently their wine. In 1878, the first cases of downy mildew were observed in France in the region of Lyon and also in Swizerland and Italy. Depending on the year, production of grapes in France has been estimated to be at a loss of 50% or more. Because of numbers and results like these, downy mildew has been considered the most devastating disease of a filamentous pathogen to affect European vineyards. In the past few months (June 2015) there has been another violent attack of mildew on the grapevines in the Aquitaine region. Up to 60% of wine grapes have been infected on certain parcels and the vice president of the agriculture chamber, Patrick Vasseur, hasn't been underestimating the economic significance this could have since the wine production will evidently be affected. He calls the situation "exceptional" since "even the main branches are affected" Serge Audubert, head of 3 castles in the region and owning a total of 24 ha, has been watching the effects on his land. On his 17 ha of château-laborde grapevines, in Saint-Médard-de-Guizières, 2 ha are severly touched. « the leaves, the branches, the grapes, everything is affected. We are going to loose at least 50% of the grapes on these 2 ha. »
On the first of may, this vinyard observed a spot on a branch, nothing severe especially since the « Bulletin de santé du végétal » which came out a few days before clearly states that the conditions dont allow contaminations. As a precaution, Serge Audubert starts his preventive treatments on the 7th of may. On the 15th of May, the outburst starts, shicking the entire region: « I have been living here since 1987. I have never seen something like this. Informatics models were supposed to alert us when mildew evolution becomes dangerous. » to be continued ...

A warm, moist, and humid environment is required. Studies in Sicily have shown optimum time for oospore germination is between the end of February and the middle of March. With this understanding, if fungicides are used just before these conditions occur, and have proven to be efficient measures. Other methods include proper watering, and a good location where the plant can receive continual sunlight.

Contacting vinyards
To try to see the effect that mildew has on wine producers iGEM Bordeaux contacted numerous castles in the region and attended the two biggest wine assemblies in Bordeaux: La foire au vin and Vinexpo. This allowed us to speak to the roducers on how much their production is threatened by oomycetes such as mildew and to see if thy would eventually be interested in an alternative preventive solution that would be eco-friendly. At the same time, this allowed us to search for sponsors in the region to raise money for our labwork
