Certis gains licence to SAR bacterium
Mitsui & Co’s US biopesticide subsidiary, Certis USA (Columbia, Maryland), has reached a global licensing deal with Montana State University (MSU - Bozeman) and Montana BioAgriculture to develop and commercialise plant disease control technologies based on Bacillus mycoides isolate Bmj. The non-pathogenic bacterium triggers plant defence responses to fungi, bacteria and viruses resulting in systemic acquired resistance (SAR). It acts similarly to chemical SAR activators but with lower risk of phytotoxicity, Certis notes. MSU has demonstrated efficacy against leaf spot on sugar beet ( Cercospora beticola), white mould ( Sclerotinia sclerotiorium) and early blight ( Alternaria solani) on potatoes and other diseases.
