Fluorescence diagnostics and photodynamic therapy of grain crops pathogenic fungi

The studies show the dynamics of photosensitizers accumulation in various grain areas during germination and their photodynamic activity against pathogenic microflora (Fusarium, Bipolaris, Alternaria). Four photosensitizers (methylene blue, Chlorin E6, aluminum phthalocyanine in molecular- and nanoform) were used in the work. The accumulation level of methylene blue and aluminum phthalocyanine in molecular form in infected by Alternaria and Fusarium fungi grains was 4-5 times higher than in control on the 4th day. The possibility of pathogenic microflora inactivation using aluminum phthalocyanine was shown.
