Le cultivateur est d\u00e9barrass\u00e9 du pythium en un rien de temps.<\/em><\/p>\n

Tholen - Les \u00e9metteurs \u00e0 ultrasons de l'USAF sont excellents pour lutter contre les algues, un ph\u00e9nom\u00e8ne visible \u00e0 l'\u0153il nu. Cependant, cela ne s'applique pas aux champignons, et m\u00eame les tests PCR effectu\u00e9s sur des \u00e9chantillons d'eau ne montrent que la pr\u00e9sence de l'ADN d'un champignon, et non pas si le champignon est vital ou non. Pour savoir avec certitude si un champignon peut affecter une culture, un examen microscopique est n\u00e9cessaire.<\/p>\n

Suite \u00e0 un contr\u00f4le p\u00e9riodique, une forte contamination par Pythium spp. a \u00e9t\u00e9 d\u00e9tect\u00e9e par Eurofins dans un silo de m\u00e9lange de 250m3. Le silo en question contient de l'eau fra\u00eeche et de l'eau de drainage.<\/p>\n

<\/p>\n

Du rapport d'Eurofins qui indiquait la pr\u00e9sence d'ADN fongique.<\/em><\/p>\n

Pour trouver un moyen de contourner ce probl\u00e8me, des transmetteurs \u00e0 ultrasons de l'USAF ont \u00e9t\u00e9 install\u00e9s dans le silo de m\u00e9lange. Cela a tu\u00e9 les champignons Pythium, mais logiquement le cultivateur voulait \u00eatre s\u00fbr. L'examen microscopique effectu\u00e9 par Eurofins a en effet montr\u00e9 que la contamination par Pythium pr\u00e9sente avait \u00e9t\u00e9 rendue totalement inoffensive, l'ADN du champignon trouv\u00e9 n'\u00e9tant plus vital.<\/p>\n

<\/p>\n

Au total, le test est rest\u00e9 \u00e0 Eurofins du 2 au 24 ao\u00fbt et pendant cette p\u00e9riode, aucune trace d'un autre champignon potentiellement dangereux n'est apparue non plus. Seules 2 petites colonies fongiques ont \u00e9t\u00e9 localis\u00e9es sur les plaques (voir image ci-dessus). Dans les deux cas, apr\u00e8s un nouveau test ADN, il s'agissait du champignon Trichoderma spp, - asperellum et - hamatum. Ce champignon est plus fr\u00e9quemment d\u00e9tect\u00e9 lors du placage et il est probable qu'il s'agissait d'un champignon a\u00e9rien. De plus, il s'agit d'un champignon inoffensif.<\/p>\n

Robert de Hoo, propri\u00e9taire d'Ultramins, est satisfait de ces r\u00e9sultats. \"C'est \u00e9videmment un excellent r\u00e9sultat et une preuve irr\u00e9futable que nos \u00e9metteurs \u00e0 ultrasons USAF\u2122 fonctionnent tr\u00e8s efficacement. Une forte concentration d'un champignon tr\u00e8s nuisible peut avoir des cons\u00e9quences d\u00e9sastreuses pour un cultivateur. Nos \u00e9metteurs contr\u00f4lent non seulement le Pythium, mais bien s\u00fbr tous les types de champignons. Nous offrons une alternative durable aux produits chimiques et autres \u00e9quipements de contr\u00f4le m\u00e9canique. Notre contr\u00f4le ultrasonique fonctionne 24 heures sur 24, 7 jours sur 7, 365 jours par an, ne n\u00e9cessite aucun entretien et fournit une eau optimale. S'il y a un probl\u00e8me de micro-organismes dans l'eau de culture, nous sommes heureux de prendre contact avec vous, et la plupart du temps, nous r\u00e9solvons le probl\u00e8me sur la base du principe \"no cure no pay\".<\/p>\n
