Phthalocyanine displays high affinity towards various polysaccharides and bacterial exopolysaccharides. A 0.01‐0.02% aqueous solution caused immediate agglutination and loss of infectivity of mucoid strains of Clavibacter michiganensis subsp. sepedonicus. Non‐mucoid strains survive in the presence of phthalocyanine due to impaired exopolysaccharide production. Agglutination and killing of mucoid phenotypes offers a better opportunity for revealing the presence of non‐mucoid phenotypes, which can avoid detection due to slower growth rate and lack of the serologically recognizable epitopes on exopolysaccharides. Phthalocyanine can be used to identify C.m. sepedonicus among other phytopathogenic bacteria and to destroy ring‐rot bacteria on the surface of contaminated tubers or other objects.
