APTIVIS fungicide is now registered for the control of black spot and powdery mildew on apples and pears, and Alternaria leaf blotch on apples.
APTIVIS is a fourth generation SDHI fungicide (Group 7) from Syngenta and contains pydiflumetofen (ADEPIDYN technology), which controls infection of these significant diseases during a period, when flowers and foliage are highly vulnerable.
Paul Hassan, technical services lead for Syngenta New Zealand, explains: “APTIVIS powered by ADEPIDYN technology is a next generation SDHI fungicide, due to its unique molecular structure and versatility. It works by interfering with the energy production of the fungal cell, making it unable to grow and reproduce, so the pathogens that come in contact with it quickly die.”
After application, ADEPIDYN technology moves quickly from the leaf or floral bud surface into the deeper plant tissues and from there systemically translocates within the plant’s vascular system.
This reservoir of active ingredient protects the growing plant tissues over an extended period to deliver powerful and dependable disease control.
“Black spot, powdery mildew and Alternaria are diseases that pipfruit growers must always contend with during spring. APTIVIS has a great technical fit in pipfruit crop protection programmes against these diseases because they are highly sensitive to the potency of the active ingredient.”
“In New Zealand development trials, APTIVIS has consistently shown a high level of control against target diseases, when compared to older generation SDHI fungicides and we are very confident of its place in a fungicide programme,” says Hassan.
Syngenta has thoroughly tested APTIVIS with other products and it has shown excellent crop safety and compatibility when applied in tank mixture with a wide range of other fungicides, insecticides, plant growth regulators and foliar fertilisers.
As well as this, it is compatible with Integrated Pest Management (IPM)programmes ensuring the safety of beneficial insects, including Aphelinus mali, when applied according to label directions.
Syngenta has a proud history of providing high-quality fungicide solutions to the pipfruit market, including trusted products such as SCORE WG, CHORUS and SEGURIS Flexi.
APTIVIS should always be applied preventatively and according to the label. To comply with current SDHI resistance management guidelines, apply a maximum of four SDHI-containing products per season in alternation with an effective fungicide from a different mode of action group.
Additionally, always apply in mixture with a multi-site protectant fungicide that is not at risk from resistance at full label rate.
APTIVIS can be applied a maximum of three times and up to four times concentrate per season from tight cluster to 90 per cent petal-fall. This pre-harvest interval will ensure nil detectable residues at harvest.
APTIVIS is available in 1 and 5 litre containers. For more information about APTIVIS use in pipfruit, contact your local Syngenta territory sales manager.
