Efficient and well-planned phytosanitary management is essential to achieve high productivity in soybean cultivation. According to information from Mais Soja, fungal diseases are among the main factors that compromise crop yield, with a focus on Asian rust (Phakopsora pachyrhizi), target spot (Corynespora cassiicola), powdery mildew (Erysiphe diffusa), white mold (Sclerotinia sclerotiorum), grain rot (Diaporthe spp. and Fusarium spp.), and late-season diseases (Cercospora spp. and Septoria glycines). In extreme cases, these diseases can cause losses of up to 90%, making production unfeasible.
