The phytotoxic pigment PKZh-1 that causes the characteristic symptoms of wilt in tests on cotton-plant shoots in a concentration of 100–150 µg/ml, has been isolated from the culture liquid of the fungusVerticillium dahliae Kleb.

On the basis of qualitative reaction, spectral characteristics, and a study of hydrolysis products, PKZh-1 has been assigned to the peptide group. A red substance identified as 3,6,8-trihydroxy-1,4-naphthaquinone has been isolated from an acid hydrolyzate of PKZh-1.
