An experiment was carried out in Ponta Grossa, Paraná State, Brazil, to evaluate the advantage of the addition of the fungicide trifloxystrobin to tebuconazole, to control the garlic rust (Puccinia porri). The experimental design was of complete randomized blocks with six treatments and four replications. The treatments consisted of tebuconazol in the rate of 200 g ha-1 (1,00 L ha-1 of Folicur 200 CE); and of the formulated mixtures of trifloxystrobin and tebuconazol in the rates of 50 and 100 e 75 and 150 g ha-1 (0.50 and 0.75 L ha-1 of Nativo SC); trifloxystrobin and tebuconazol in the rates of 50 and 100 e 75 and 150 g ha-1 (0.20 and 0.30 kg ha-1 of Nativo WG) and non sprayed control. Three applications of the fungicides were carried out at 85, 96, and 103 days after the plant emergence, cultivar Caçador. Disease was assessed at 11, 18 and 27 days after the first application of fungicides. Under Puccinia porri high severity observed in the experiment, the mixture of the trifloxystrobin and tebuconazol in the rate of 75 and 150 g ha-1 of SC and WG, showed similar control of the garlic rust as compared to tebuconazol, fungicide recommended for the rust control and for not causing visible damages in the culture.
