1960 I. A. M. Cruickshank & D. R. Perrin in Nature 27 Aug. 800/1 We propose that the trivial name of this compound should be ‘pisatin’ after the host plant from which it was originally isolated.

1972 S. A. J. Tarr Princ. Plant Pathol. xiv. 268 Pisatin..is formed when dilute solutions of certain metallic salts..are placed on pea pod endocarp tissue.

2001 Fungal Genetics & Biol. 33 37 Many fungi that are pathogenic on pea have the ability to demethylate and thus detoxify the pea phytoalexin pisatin.
