You are here

Lyon, 4th Mai 2018 - AMOEBA announces today the first greenhouse test results conducted with the microorganism, Willaertia magna C2c Maky, used as a biocontrol agent for the control of mildew on grapevine.

 The results of the first greenhouse trials show very clear dose-responses of Willaertia magna C2c Maky in a formulated product. The efficacy of more than 90% of the formulated product on mildew has to be compared to the usual efficacy of biocontrol agents of around 50% observed in greenhouses. A new series of tests is scheduled in 2018 in preparation of the field trials planned in 2019. 

These first greenhouse tests, which confirm the previous in vitro trials (see our press release dated November 22, 2017), are a fundamental milestone to validate the potential use of Willaertia magna C2c Maky as an alternative to traditional chemical products. These tests were carried out by CONIDIA, an independent recognized expert in fungi and their resistance to fungicides.

This milestone will enable the Company to start working on the regulatory dossier and to accelerate the discussions with the key market players in view of a potential partnership.

«We consider the results of those first greenhouse tests as very promising on the basis of the efficacy usually reached with some biocontrol products of around 50% », states Sébastien VACHER, Global Manager de CONIDIA. « Those results were obtained in robust trial conditions, in line with the good practices for trials conducted for plant protection products. », added Sébastien VACHER.

« As mentioned by the French Institute for vine and grapevine (Institut Français de la Vigne et du Vin), the most effective biocontrol product only brings a rate of 20 to 30% efficacity in field trials. Our level of efficacy reaches 90% in greenhouses which would allow us, after validation of field trials, to offer a real alternative solution meeting the essential market needs. This is a key turning point for the global players to enable them to come forward as potential co-developer or partner with Amoéba. Thnaks to this success, we are now targeting other crop diseases on crops (such as tomatoes, beetroots, potatoes,..) in order to broaden our portfolio », states Fabrice PLASSON, CEO of AMOEBA.
