  • Method of protecting an object against the attack of destructive fungi employing perdeuteriated N-hendecanoic acid or 2,2-dideutero-N-hendecanoic acid
    Patent number: 4473585
    Abstract: A carboxylic acid, its salts, esters and derivatives, in which the hydrogen atoms have been replaced, partly or entirely, by deuterium has an antimycotic effect, probably because the fungi cannot metabolize the deuteriated substance. The deuteriated substances can be used for treating living plants, seeds and wood against the attack of destructive fungi, and for curing pathogenic infections of fungi in humans and animals.
