New in-furrow fungicide fights potato pink rot in Canada

Syngenta Canada Inc. is launching Orondis Gold Potato fungicide for suppression of pink rot and Pythium leak in potatoes

Pink rot is a soil-borne disease that thrives in wet, poorly drained soils and can survive in soil for up to seven years. Just a few infected potatoes entering the storage bin can result in substantial losses, infecting healthy tubers and compromising marketable yield.

Orondis is applied in-furrow as part of a preventative disease control program. It combines metalaxyl M (Group 4) with oxathiapiprolin (Group 49) – a new mode of action to suppress pink rot and help manage the development of resistance.

The product is crop safe, so it does not put undue stress on foliage, the company notes in a press release. It also provides suppression of Pythium leak, which enters tubers through wounds or bruises that occur during harvest and grading.

According to the label, Orondis Gold Potato should be applied at a rate of 3.2 mL/100 metre row of Orondis Gold A 200 C and 4 mL/100 metre row of Orondis Gold B 480 L. One case will treat 40 acres in 36 inch row spacing. To help manage resistance, the company advises growers using the product in furrow they cannot make any subsequent Orondis Ultra foliar fungicide applications.
