August 31, 2009, Guelph, Ont. – Potato growers across Canada now have the option of applying Scala fungicide by air for control of early blight.

Scala is the only Group 9 fungicide registered to control early blight (Alternaria solani) in potatoes, and has been registered as a ground application since 2007.
 
Scala has a unique mode of action – different than strobilurins – and is registered as a tank mix with Bravo® to provide two modes of action for stronger resistance management. Scala protects potatoes through locally systemic activity and translaminar movement, and is best suited for a preventative treatment program.
 
“Large-scale potato growers, particularly in Alberta and Manitoba, will benefit from the convenience and efficiency of aerial early blight control,” says David Kikkert, portfolio manager of horticulture with Bayer CropScience. “Prevention is the best strategy for early blight, and the new aerial application means growers will have the option of choosing Scala to get an early start on protecting their potato crop.”
 
For aerial application, apply Scala only by rotary or fixed-wing aircraft when conditions are conducive to disease development and when meterological conditions allow for complete and even crop coverage. Repeat applications at seven to 14 day intervals, to a maximum of six applications per season, and alternate Scala applications with fungicides that have a different mode of action. Refer to the full product label for specific Scala aerial application instructions.
 
Scala is a critical component in a fungicide management program in potatoes. For potato-growing areas where reduced sensitivity to strobilurins has been identified, Scala provides excellent disease control and a smart rotational tool.
 
Scala is also registered for control of a variety of diseases in apples, pears, grapes and strawberries.
