I have used Alliette in compost to prevent Phytophthora cinnamomi in woody plants for some years. It has been withdrawn. Has anybody experience with Prestop (Registered by Verdera Oy in Finland, supplied by Fargro in UK) containing Gliocladium catenulatum? It is said to control Pythium, Phytophthora, Rhizoctonia and Fusarium when used in growing media, and Didymella and Botrrytis when used as a foliar spray.
Are there any other suggestions?
