Evaluation of Syngenta and competitor seed treatments for control of seed-borne cereal pathogens.

This study evaluated the effect of seed treatments for suppression of seed-borne pathogens on naturally-infested wheat seeds in a plate test and on seed germination in a blotter paper assay. Canada Prairie Spring cultivars, “Hanley” and “Pasteur”, were tested with the following seed treatments: Vibrance® Quattro, a premix of difenoconazole, sedaxane, fludioxonil and metalaxyl-M, and Vibrance XL plus Proseed®, a premix of difenoconazole, sedaxane and metalaxyl-M combined with fludioxinil (Syngenta Canada Inc.), Insure® Cereal (pyraclostrobin, triticonazole and metalaxyl) (BASF Canada Inc.), Raxil® Pro (tebuconazole, prothioconazole and metalaxyl) (Bayer CropScience Inc.), Rancona® Apex (ipconazole) and Vitaflo® (carbathiin and thiram) (Chemtura Canada Co.). Vibrance Quattro and Vibrance XL plus Proseed seed treatments had less total pathogen incidence (%) and area of colonization (%) on both cultivars relative to untreated controls and other treatments. Also, the Syngenta seed treatments had better suppression of Fusarium graminearum Schwabe (teleomorph Gibberella zeae (Schwein.) Petch) and Alternaria sp. on “Hanley” and Alternaria sp. on “Pasteur” compared to other seed treatments. Incidence of Aspergillus sp., Cladosporium sp., Epicoccum sp., other Fusarium spp. and Penicillum sp. were also assessed. Germination was higher in all seed treatments compared to untreated control in “Hanley”; only Vibrance Quattro and Vibrance XL plus Proseed had higher germination than the untreated control in “Pasteur”. All of the treatments were equally effective for germination in both cultivars. Syngenta’s seed treatments improved germination of infested wheat seeds over untreated seeds, and suppressed total incidence and area of colonization of seed-borne pathogens better than competitor seed treatments.
