Syngenta New Zealand launched Proclaim Opti, a new and enhanced formulation of emamectin (Group 6 insecticide), to both markets last year.
It is approved in the Zespri Crop Protection Standard with a 42-day pre-harvest interval.
Syngenta customer marketing lead Raeleen Watherston says Peptite granule technology means superior handling with less dust, and applicators have been impressed with how easily the water dispersible granules dissolve in water.
Proclaim Opti is a fast-acting selective insecticide that has both direct contact activity on leafrollers as well as ingestion activity on feeding larvae.
Larvae exposed to the active stop feeding within one to two hours, which prevents further crop damage, Watherston says.
However, it can take several days for them to disappear from the canopy.
Because it’s a translaminar insecticide, the active ingredient emamectin is quickly absorbed into the plant tissue
“This provides excellent efficacy and residual activity but also limits the impact on key beneficial species.”
The product was initially launched to apple and pear growers in 2020.
The active ingredient emamectin is also formulated with a photo-protectant coating. This helps block the UV radiation from sunlight and therefore delays the on-set of degradation, allowing the product to remain active on the plant surface for longer.
This feature increases the foliar uptake of the active ingredient and improves control by ingestion, resulting in the addition of a codling moth control claim to the label along with leafrollers. It is now a solid, late season control option for both these pests.
This season Syngenta has introduced a new smaller 80 gram pack for smaller orchards.
This is in addition to the 400 g packs launched last season.
