MODE OF ACTION

Uster Top 32.5% SC contains two active ingredients;

Azoxystrobin 200 g/L + Difenoconazole 125 g/L

• Azoxystrobin belongs to Strobilurin chemical group. It acts by inhibiting spore germination during early stages of fungal growth. Azoxystrobin interferes with mito-chondria respiration by disrupting the energy within the fungus and interrupting the biosynthensis of ergosterol. This disrupts the fungal life cycle mainly during spore germination, infection and hyphen growth.
• Difenoconazole belongs to Triazole chemical group. It is absorbed by the plant and works on the fungal pathogens by interfering with biosynthesis of sterols in cell membranes during penetration and haustoria formation. It has protective and cura-tive properties and it is recommended during early stages of diseases cycle to minimise on fungal pathogen build up as well as irreversible damage to the crop.
