Mode of action
Azoxystrobin inhibits spore germination at the early stages of fungal development, this confers excellent protection against invasion by fungal pathogens. It is also active against post-germination stages of the life cycle in a broad range of fungal species. Azoxystrobin also confers anti-sporulant activity against a wide range of diseases.
Difenoconazole is taken up by the plant and acts on the fungal pathogen during penetration and haustoria formation. It stops development of the fungi by interfering with the biosynthesis of sterols in cell membranes. Although the mode of action permits protective and curative use, it is recommended to apply the product early enough to avoid irreversible crop damage and build-up of the disease.
