Features of Ortiva Top

• Package size: 500mL.
• Formulation: Suspension Concentrate (SC).
• Active substance: 200 g/L azoxystrobin, 125 g/L difenoconazole.

 

Mode of action

Azoxystrobin:

• It inhibits spore germination at the early stages of fungal development. This confers excellent protection against invasion by fungal pathogens.
• It acts as an inhibitor of mitochondrial respiration, blocking the energy cycle of the pathogen.
• Mainly occurs in the biological cycle of the fungus, during spore germination, and during the initiation of penetration into the tissues of the plant.
• Gradual uptake and systemic local activity in leaves.

Difenoconazole:

• Blocks steroid biosynthesis in cell membranes of fungi.
• It offers preventive and curative action.
• Local systemic action and easy acropetal translocation.
