The efficiency of seed treatment with different fungicides and mixtures was evaluated for the control of Sclerotinia sclerotiorum and Alternaria spp. in sunflower seeds. Achenes of the hybrid Contissol infected with S. sclerotiorum were treated with the following fungicides: benomyl (Benlate 50 WP) 3.5g a.i./kg; carboxin (Vitavax 75 WP) 5.25g a.i./kg; thiabendazol (Tecto 10) 1.4g a.i./kg; thiabendazol 1.4g a.i./kg + carboxin 5.25g a.i./kg; thiabendazol 0.7g a.i./kg + carboxin 2.625g a.i./kg. The treatments were evaluated by the blotter test, PDA and emergence in greenhouse. High levels of S. sclerotiorum and Alternaria spp. were observed in the untreated seeds in PDA and blotter. Carboxin 5.25g a.i. drastically reduced Alternaria spp. but had no effect on S. erotiorum. Thiabendazol 1.4g and benomyl 3.5g efficiently controlled S. sclerotiorum, but did not affect Alternaria spp. The mixture thiabendazol 1.4g + carboxin 5.25g was very effective in controlling the pathogens, and resulted in the best seed emergence index in greenhouse. Half dosage treatments were not efficient in controlling the pathogens. Based on the results, seed treatment with the misture thiabendazol 1.4g + carboxin 5.25g is the most efficient way of reducing seed transmission and dissemination of those pathogens. |
