Abstract
Novel compounds of formula I ##STR1## wherein R.sup.1 is independently hydrogen, hydroxy, alkyl with 1 to 6 carbon atoms, acyloxy groups with 1 to 6 carbon atoms, alkyloxy with 1 to 6 carbon atoms or from 1 to 5 sugar moleties; and R.sup.2 is independently hydrogen, or alkyl with 1 to 6 carbon atoms. The compounds are producible by aerobic cultivation on suitable nutrient media under suitable conditions of a strain of the fungus Ascochyta sp., subsequent recovery of the active component from the fermentation medium, and optionally modifying the active compound to obtain a compound of the desired formula I. Disclosed is also microorganisms capable of producing said compounds, compositions containing said compounds, and the use of such compositions for controlling fungi in valuable crops, animals, including birds and mammals, and in the preservation of wood, paints and edible products.
