Considering the potential of Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, to reduce soybean yield, different control strategies need to be used. This study investigated the potential of using a phosphite (30 and 20% of phosphorus and potassium, respectively) combined with L-α-free amino acids (Optimus®, Bioiberica, Spain) to reduce ASR symptoms and helping the plants to have a better photosynthetic performance during the fungal infection process.
