A fungicide to control late blight in potatoes, among other vegetable crop diseases, has been launched in a co-pack to also attack early blight in potato crops.
Syngenta Crop Protection Canada on Wednesday announced its Group 40 mandipropamid fungicide Revus will join difenoconazole, a Group 3 triazole fungicide, in a co-pack dubbed Revus Top.
“Revus should play a part of potato growers’ spray program, applied at critical periods to control late blight,” Tara McCaughey, technical crop manager for Guelph-based Syngenta, said in a release.
Growers who also see early blight pressure in their potato plots will find Revus Top a “valuable option” to protect against that disease as well, she said.

Bargain buying and short covering lifted U.S. corn futures on Monday after the market slid to contract lows on expectations for strong U.S. output, traders said.
Once applied, the translaminar movement of difenoconazole provides for both contact and residual disease control, the company said, adding that the chemical’s movement also contributes to the fungicide’s effectiveness at low use rates.
In the Revus Top co-pack, difenoconazole will be available in a liquid formulation at 250 grams per litre of emulsifiable concentrate, the company said. Revus itself is sold as a suspension, also at 250 g/L.
Syngenta already markets difenoconazole as one of the active fungicides in its seed treatments Dividend XL RTA, Helix XTra and Cruiser Maxx Cereals.
