The invention relates to fungicidal plant protecting composition comprising 3-90% by weight of a fungicidal active ingredient in admixture with 1-90% by weight of cyclodextrin and optionally with usual auxiliary agents. The advantage of the synergistic composition of the present invention is that identical fungicidal effect can be achieved with a significantly lower active ingredient dosage and this decreases the costs involved with the active ingredient and reduces the risks of environmental pollution as well.

Process for enhancing the activity of plant protecting agents by using

The invention relates to new phenanthrene derivatives wherein R stand for C.sub.1-10 alkylamino; C.sub.1-10 alkylthio; C.sub.1-5 alkoxy; or phenyl or phenylamino, the two latter groups being optionally substituted on the phenyl ring by one or more identical or different C.sub.1-4 alkyl, C.sub.1-4 alkoxy, nitro, amino, cyano and/or halogen substituent(s) . The compounds of the present invention possess valuable fungicidal properties and may be used in agriculture, horticulture and therapy as active ingredient of fungicidal or antifungal compositions. The compounds of the general Formula I ##STR1## may be prepared by acylating 9,10-phenanthrene-dione-9-oxime or an alkali or alkali earth metal salt thereof.
