Abstract: Novel compounds of the general composition I, Lactate (1), Glycine (1), Valine (4), Isoleucine (1), pipecolic acid (1), Aspartic acid (1), Tyrosine (1), wherein each amino acid residue independently may occur in L- or D- form, and wherein the number in parenthesis indicates the number of occurrences of each moiety, and derivatives thereof are disclosed. The compounds are producible by aerobic cultivation on suitable nutrient media under suitable conditions of a strain of the fungus Curvularia sp., subsequent recovery of the active component from the fermentation medium, and optionally modifying the active compound to obtain a compound of the desired general composition. Disclosed are also microorganisms capable of producing said compounds, compositions containing said compounds, and the use of such compositions for controlling fungi in crops, and in the preservation of wood, paints, cosmetics, and edible products.

Abstract: Fungicidal compositions comprising compounds of the general formula III ##STR1## cyclo-[Pec-MeAsp-MeVal-Val-MeVal-MeIle-Gly-MeVal-TyrOMe-D-Lact] (III) wherein each amino acid residue and the lactate residue independently may occur in L- or D-form, and derivatives thereof in combination with other biocidal agents are disclosed. Said compositions may be used for controlling fungi in crops and in the preservation of wood, paints, cosmetics, and edible products.

Abstract: The invention is directed to compounds having general formula (I) or general formula (II). Compounds of formulae (I) or (II) have interesting antifungal activities and may, accordingly, be used as active ingredients in fungicidal compositions.
