Elucidation of the distribution of airborne fungi in some plastic greenhouses for agriculture and their outsides

-We paid attention to existence of the fungicide-tolerant Botrytis spp. in the Asahikawa area-

Abstract

To explain the fungal contamination in the agricultural area of Asahikawa suburbs, we explained airborne fungal flora in three plastic greenhouses for hydroponic culture of vegetables and in the neighborhood area by use of an air sampler from February in 2007 to January in 2009. Furthermore, antifungal effects of sterilizer for several kinds of agriculture on 73 isolates of Botrytis spp. collected from airborne fungi and the vegetables were studied. As a result, it was revealed that 26 strains of 73 strains (36%) showed tolerance to Thiophanate-methyl (TM) / Iprodione (Ro) water dispersible powder agents.

ANCT-06001 of the multidrug-tolerant strain was accepted as Botrytis sp. NBRC 114508 in June, 2020.
