Nufarm receives registration for new apple fungicide

March 30, 2021  By Fruit and Vegetable

Nufarm, in partnership with Valent Canada, recently announced the registration of Excalia, their newest horticulture fungicide for control of scab and powdery mildew in apples and suppression of rhizoctonia crown and root rot in sugar beets.

To protect apples against scab and powdery mildew, Excalia delivers locally systemic and translaminar action for complete leaf tissue uptake and distribution across the entire leaf surface. This Group 7 SDHI (succinate dehydrogenase inhibitor) fungicide is a great early season product and features the active ingredient INDIFLIN.

“The key with most diseases is early season preventative treatment,” said Alicia Sebastian, horticulture sales specialist at Nufarm, in a press release. “For apple growers especially, Excalia is a new tool that helps them get a clean start to the season and minimize spreading of primary scab and powdery mildew.”

In apples, Excalia must be applied between green tip and petal fall. Excalia is highly active against the apple scab pathogen and works to inhibit spore production, spore germination and actively growing fungi. For powdery mildew protection, Excalia must be applied with a silicone surfactant; it tank-mixes well with other fungicides and foliar nutrients, providing flexibility in early season spraying.

Excalia is available for the 2021 season. Application timing is approaching and growers are encouraged to book product now. For additional information go to or call 1-800-868-5444.
