Syngenta's Allegro fungicide now registered for apples, carrots and ginseng

Syngenta is pleased to announce 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. “This multi-site mode of action provides a significant advantage, making development of resistant disease strains extremely unlikely. Activity against spores also successfully isolates the disease lesions and prevents fungal spread.”

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.

Steve Gomme, Syngenta Customer Marketing Manager for Horticulture, adds that the availability of Allegro is particularly welcome news for Canadian apple growers. “Allegro provides control, or suppression, of most apple foliar and fruit diseases. Another unique benefit of Allegro is that, unlike other apple fungicides, it provides control of some of the major mites that infest apple orchards.”

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).
