The selectivity of benzimidazole-fungicides: consequences for post-harvest fruit decay control

Richter K., . (1996) The selectivity of benzimidazole-fungicides: consequences for post-harvest fruit decay control. [Proceedings Paper]

Benzimidazole compounds have been reported to control numerous plant diseases but were nontoxic to certain taxonomic groups including such important pathogens as Altemaria Geotrichum and species of Phycomycetes. In our research an increasing share of pathogens insensitive to this compounds mainly Altemaria and Geotrichum could be measured on the German market. Tests with Benzimidazole-fungicides in vitro and in vivo have demonstrated mycelial growth in media containing up to 7 000 ppm a.i. the selection of insensitive pathogens from an mixed inoculum and stimulating effects on sporulation as well as disease incidence. Because these fungi are responsible for diseases on fruits from different host families and known as producers of mycotoxins and causes of diseases in humans and animals the consequences of the selective effects of Benzimidazoles for postharvest technology and the requirements for an effective control strategy are discussed from the viewpoint of Germany as an importer of tropical fruits.

Abstract

Benzimidazole compounds have been reported to control numerous plant diseases but were nontoxic to certain taxonomic groups including such important pathogens as Altemaria Geotrichum and species of Phycomycetes. In our research an increasing share of pathogens insensitive to this compounds mainly Altemaria and Geotrichum could be measured on the German market. Tests with Benzimidazole-fungicides in vitro and in vivo have demonstrated mycelial growth in media containing up to 7 000 ppm a.i. the selection of insensitive pathogens from an mixed inoculum and stimulating effects on sporulation as well as disease incidence. Because these fungi are responsible for diseases on fruits from different host families and known as producers of mycotoxins and causes of diseases in humans and animals the consequences of the selective effects of Benzimidazoles for postharvest technology and the requirements for an effective control strategy are discussed from the viewpoint of Germany as an importer of tropical fruits.
