Allegro fungicide registered for apples, carrots

November 30, 1999  By Syngenta Canada

June 28, 2011, Guelph, Ont – Syngenta recently announced that Allegro®500F fungicide is now registered for use on apples, carrots and ginseng, in time for the 2011 Canadian growing season.

This newly expanded label for Allegro is in addition to its existing registration for disease control in crops including: potatoes, edible-podded legume vegetables (except peas), beans, dry beans, brassica leafy greens, bushberries (crop subgroup 13B) cabbage, broccoli and cauliflower.

Allegro, a broad-spectrum fungicide, contains the active ingredient fluazinam. The unique activity of this product allows for effective control of a broad range of diseases at low use rates making it an ideal rotational partner. Allegro is also the only available crop protection product from the pyridinamine class of chemistry (Group 29).


“Allegro stops fungus in two ways – by inhibiting its respiration and by reducing energy within the fungus – which prevents spore germination,” says Tara McCaughey, technical crop manager for Syngenta Canada.

In apples, Allegro provides effective control of the following diseases: apple scab (Venturia inaequalis); flyspeck (Schizothyrium pomi) and sooty blotch (Gloeodes pomigena). Plus, it’s registered for the suppression of mites.

Allegro also controls important diseases that afflict ginseng: rhizoctonia root rot (Rhizoctonia solani); alternaria blight (Alternaria panax); and botrytis blight (Botrytis cinerea). When applied to carrot crops, Allegro controls white mould (Sclerotinia sclerotiorum) and alternaria leaf blight (Alternaria dauci).
