Bean growers in Canada, who until now have only had one approved product for use against white mold in dry bean crops, have been granted an alternative.
Syngenta Crop Protection Canada on Tuesday announced it has picked up a minor-use registration for its fluazinam (Group 29) fungicide Allegro 500F as a treatment to control white mold in dry beans.
In an integrated pest management (IPM) program, Allegro “offers sustainable white mold management with little risk of resistance,” the company said in a release.
Syngenta brand manager Andrea McConnell described Allegro as “a new and more effective alternative” to the lone product otherwise available to dry bean growers against white mold (Sclerotinia sclerotiorum).

Alberta Crop Report: Rains in the south, dryness in the north
Rain fell onto the southern half of Alberta last week, while hot and dry conditions persisted in the northern half, according to the province’s crop report released on July 18.
The company didn’t name names, but one of its own brands, the cyprodinil/fludioxonil (Group 9/12) combination fungicide Switch 62.5 WG, is also registered for control of white mold in dry beans in Canada.
Allegro, previously approved for control of late blight in potatoes, is also billed as the only crop protection product available from the pyridinamine class of chemicals, and as a protectant non-systemic fungicide with “multi-site mode of action.”
The company cited three consecutive years of field trials at the Huron Research Station at Guelph, in which average yield increases of 27 per cent with Allegro and 37 per cent with an Allegro/Quadris tank mix were reported, compared to the untreated check.
Allegro was developed and first registered by ISK Biosciences, the U.S. wing of Japanese chemical firm ISK. Syngenta distributes it both in Canada and in the U.S., where it’s sold under the brand name Omega 500F.
