Abstract Soybean is frequently affected by pathogenic fungi, which are usually managed chemicals. Foliar sprays with biological agents have been introduced as new allies to reduce plant diseases. This study verified foliar of Bacillus subtilis‐ based product applied for three consecutive cropping seasons associated or not chemical fungicides control Asian rust ( Phakopsora pachyrhizi ) and the effect B. subtilis ‐produced metabolites against fungi on soybean growth. Field treatments were follows: (i) application ‐based product, followed sprays; (ii) management alone; (iii) alone, (iv) treatment water sprays. In years, alone chemicals reduced at least 75% severity, similar management. Moreover, grain yield increased when was Cell‐free filtrates volatile organic compounds (VOCs) from isolate formulated bioproduct tested pathogens Fusarium cf. incarnatum / equiseti Macrophomina phaseolina . All VOCs emission more than 40% mycelial growth both fungi. Also, stimulated a rate bioproduct, indicating potential promote Therefore, showed satisfactory protection increment antagonized
