Popis:	A new HD-1 standard, HD-1-S-1980, has replaced HD-1-S-1971, whose supply has been exhausted. In comparative bioassays by five laboratories, using HD-1-S-1971 and E-61 as standards, the potency of HD-1-S-1980 was determined to be 16,000 IU/mg. Unlike HD-1-S-1971, HD-1-S-1980 is homologous with normal HD-1's in respect to its relative activity towards Trichoplusia ni (Hubner) and Heliothis virescens (F.) larvae.
