Abstract: Control efficacy of 400 g/L Tebuconazole稰rochloraz emulsion in water (EW) on controlling banana black spot were studied in field at three dosages (1000, 1500 and 2000 times liquid). The results showed that all treatments with three dosages showed a certain disease controlling function on banana black spot, the control efficiency of both 1000 and 1500 times liquid of Tebuconazole稰rochloraz EW reached more than 78% after 7 days of the third treatment, but it was lower in 2000 times liquid. Therefore, the 1000-1500 times liquid of Tebuconazole稰rochloraz EW was recommended to apply in prodiction practice.
