What is "botrydial"

Botrydial is a phytotoxic sesquiterpene metabolite secreted by the fungus Botrytis cinerea. Botrydial was first isolated and described in 1974. Botrytis Cinerea is the causal agent of gray mold disease and is known to attack a wide range of plants (over 200 species) producing leaf-spot diseases and mildews on lettuces and tomatoes as well as rotting berries. For this reason, botrydial, as well as other Botrytis Cinerea originated sesquiterpene metabolites, represent an economically important disease for ornamental and agriculturally important crops. From all the metabolites produced by this fungus, Botrydial exhibits the highest phytotoxic activity.
