How it is made

Hardegger, nikles, helv chim acta 39, 505 (1956)...

Large quantities of fusaric acid were produced by fusarium species grown on a modified richards medium containing 2 molar, but not 0.05 molar glucose.

Antibiotic (wilting agent) first isolated from the fungus fusarium heterosporium, nees: yabuta et al, j agr chem soc japan 10, 1059 (1934). Isolation from other fusarium species & from gibberella fujikuroi & synthesis: plattner et al, helv chim acta 37, 1379 (1954).
