Amoéba: publication of a scientific article concerning the efficacy of its biocontrol products to fight potato late blight 

Chassieu (France), October 18 2022 – 5.45 pm – AMOÉBA (FR0011051598 – ALMIB), producer of a biological biocide capable of eliminating the risk in water and human wounds, and of a biocontrol product for plant protection, still in the testing phase, announces the publication of a second scientific article on its biocontrol application ( in the special issue « Plant Bioprotection » de Plants, journal of the MDPI Group, peer-reviewed. 

This paper presents, for the first time to the international scientific community, the efficacy of the biocontrol products based on the lysate of the amoeba Willaertia magna C2c Maky on potato late blight. Scientific data demonstrating the dual mode of action of the lysate to control potato late blight are presented: 

– the indirect effect via the stimulation of the plant’s natural defences 

– the direct anti-germinative effect against the pathogen, Phytophtora infestans, responsible for potato late blight. 

The data, collected in trials carried out by independent service providers, that have demonstrated efficiency in greenhouses and in the field (2020 and 2021 seasons), are also published. They show that lysate of the amoeba Willaertia magna C2c Maky, a product of natural origin, protects plant without additional treatment up to 77% when the disease was low (28% of the surface of the untreated plants affected) and up to 49% when the untreated plants were destroyed at 100%. A yield increase was also obtained with up to 30% more tubers. 

« This second scientific paper in the frame of plant protection area, dealing with the efficacy of our biocontrol solution against potato late blight, is part of an ongoing effort to increase scientific knowledge on the amoeba Willaertia magna C2c Maky. It confirms its strong potential as a plant protection agent. We are continuing R&D operations and tests on other crops, the results of which will also be the subject of new publications,” says Dr Sandrine Troussieux, chief scientific officer at Amoéba.
