Syngenta’s Vibrance Ultra Potato seed treatment has been registered as a seed piece treatment, according to a company news release on Nov. 5, 2018.
It combines difenoconazole (Group 3), sedaxane (Group 7), and mandipropamid (Group 40) in a liquid pre-mix formulation to protect potato seed pieces and seedlings so the crop gets off to the best possible start.
Shaun Vey, seedcare and inoculants product lead with Syngenta Canada says “during the cutting and treating phase, it helps prevent the spread of seed‑borne late blight from infected seed to healthy seed. After planting, it moves within the plant, providing protection from diseases such as seed‑borne silver scurf, Fusarium dry rot, and seed-borne black scurf, stem, and stolon canker (Rhizoctonia), as well as suppression of pink rot.”
Vey says the registration of Vibrance Ultra Potato gives growers an excellent liquid fungicide-only option.
It also provides greater flexibility when treating seed pieces. The Vibrance Ultra Potato jug features a built‑in second container with a colourant, so growers can visually evaluate coverage of seed pieces and also consider additional pest protection by mixing it with colourless formulations, such as Fortenzainsecticide for control of Colorado potato beetle, if needed.
As per the label, Vibrance Ultra Potato should be applied at a rate of 32 mL/100 kg of seed. Each case contains 4 x 4.8 L + 4 x 0.8 L (colourant) jugs. One jug will treat 330.6 cwt.
