Resumen
Soybean crop has a great social and economic importance worldwide, but its production has been limited by diseases that affect the crop. The cost and the reduced efficiency of existing fungicides on the market causes new disease control alternatives to be studied. The aim of this study was to evaluate the efficiency of different commercial sources of phosphite and acibenzolar-S-methyl (ASM) applied in isolation and in combination with fungicides in the disease severity, yield components and soybean productivity. The study was conducted in the experimental area of the Universidade Tecnológica Federal do Paraná, campus Dois Vizinhos in the 2015/2016 crop. The experimental design was in randomized blocks, composed of twelve treatments involving three resistance inducers: phosphite Manganese (Ultra Mn10 [marca registrada]) Phosphite Copper (Cubo700 [marca registrada]) Phosphite Potassium (Ultra K10 [marca registrada]) and acibenzolar-S methyl (Bion [marca registrada]) and two fungicides Azoxystrobin + Cyproconazole (Priori Xtra) and Azoxystrobin + Benzovindiflupir (Elatus [marca registrada]) with three repetitions. There was a synergistic effect between the association of phosphite and acibenzolar-S-methyl sources with the fungicides molecules, resulting in a lower severity of diseases and consequently an increase in crop yield.
