    • This invention concerns sulfur-containing hydroxy pyrones corresponding to the formula ##SPC1##Wherein M is H or alkali metal, R is methyl, R' is hydrogen, alkyl, phenyl, halophenyl, nitrophenyl, loweralkylphenyl, benzyl, phenethyl, naphthylmethyl, halobenzyl, loweralkylbenzyl, nitrobenzyl, propargyl, allyl, cyclohexyl loweralkyl, (loweralkylthio)-loweralkyl or adamantyl and n is 0 to 2. The compounds are prepared by reacting the mono-alkali metal salt of 4-hydroxy-6-methyl-2-pyrone with an appropriate thiosulfonate, advantageously in the presence of an organic solvent. The compounds have utility as plant growth stunters and as antimicrobial agents.
