Potato growers will have two more crop protection options next year.

Two pesticides, a joint fungicide-insecticide seed-piece treatment dubbed Emesto Complete and a fungicide-nematicide called Velum Rise, passed Canada’s regulatory bar in late September.

Both come from Bayer Crop Science and are based on previous products. The company announced the Canadian registrations Sept. 19.

Who pays for plant breeding? A renewed push for farmer levies

With fed support on the decline, grain sector faces tough choice: pay more out-of-pocket or fall behind global competitors.

The broad-spectrum seed treatment bases its insect control on clothianidin (Group 4), while its defence against fungal disease is drawn from prothioconazole (Group 3) and penflufen (Group 7), according to its registration.

The company has earmarked the product against Colorado potato beetle, aphids, flea beetles, potato leafhopper and black scurf, stem and stolon canker.

The product is also meant to be effective against pesticide resistant strains of fusarium dry rot, according to Bayer.

The application capacity of the product is estimated at one jug per 425 hundredweight of seed potatoes.

Bayer has pitched the pesticide as an “all-in-one seed-piece treatment,” read a statement from the company’s fruit and vegetable campaign marketing manager, Meghann Garlough.

She said the new product will require low water volumes and can work at low doses.

The other new offering from the company is a Group 7 product based on fluopyram and penflufen. The in-furrow pesticide is registered for control against black scurf, stem and stolon canker and to reduce early blight, black dot and nematode-driven disease, the company said.
