MG BioFormula™ No.3 (Cankers) is a multi-strain microbial inoculant for treating tree canker diseases such as Phytophthora palmivora in durian. Plants have the ability to recognize the microbial activities induced by such multi-strain microbial inoculants and trigger an immune response. This phenomenon is called systemic acquired resistance or SAR. SAR helps plants resist diseases or recover from diseases such as cankers once infected.
