APVMA - Public Release Summary on the evaluation of the new active famoxadone in the product Zorvec Encantia Fungicide

The APVMA is considering an application for the registration of Corteva Agriscience's product Zorvec Encantia Fungicide, containing 300 g/L famoxadone and 30 g/L oxathiapiprolin, as a suspension concentrate (SC) formulation. The product is intended for the control of downy mildew caused by Peronospora spp. in spinach and rocket.

The active constituent famoxadone acts via inhibition of fungal mitochondrial respiration (at complex III), resulting in decreased ATP production. It is active against zoospore germination and mycelial growth. 

The active constituent oxathiapiprolin acts via inhibition of an oxysterol binding protein (OSBP) in fungal cells, which inhibits zoospore release and motility and sporangia germination.

The formulated product Zorvec Encantia Fungicide is intended for the control of certain fungal diseases in spinach and rocket.

Products containing oxathiapiprolin are currently registered as a fungicide for control of downy mildew in bulb, brassica, cucurbit and leafy vegetables, and oilseed poppies.

The product will be applied by ground boom, with label restraints restricting application by aircraft and equipment carried on the back of the user or by other manual application methods (e.g., handwand/handgun).

The APVMA invites comment from 1 October 2024 to 29 October 2024 on whether registration of the product should be granted.

The APVMA is able to consider comments relating to the legislative grounds, including:

• occupational health and safety

• public health

• chemistry and manufacture

• residues in food

• environmental safety

• trade

• efficacy and target crop safety.
