Abstract

This two-year study targeted measuring the effect of three different fungicide formulations in order to control soybean rust (Phakopsora pachyrhizi). This study also measured the effect of controlling soybean rust by adding a fixed concentration, 1 % v/v of two adjuvants into the three fungicide formulations and then varying the concentration of the two adjuvants at 0.5, 1.0, and 1.5 % into a tebuconazole formulation only. The first year of the study was conducted in the field in two regions of the Paraná State (Southern region of Brazil). The second year of the study was conducted in a greenhouse and in the field.
