Abstract

Il est prévu un agent de contrôle pour maladies provoqués par des fongus filamenteux de plante, caractérisé en ce qu'un polyphénol végétal ayant une activité antimicrobienne contre les fongus filamenteux pathogènes de plante est contenu comme ingrédient actif. On peut ainsi éviter les poussières de récoltes conventionnelles extrêmement toxiques et obtenir un agent de contrôle tout à fait inoffensif pour les maladies provoquées par les fongus filamenteux de plante. En outre, on peut résoudre le problème du mildiou des végétaux par fongus filamenteux pathogènes de plantes.
