The stability of pyrethroid concentrates and pure esters


, : The stability of pyrethroid concentrates and pure esters. Pyrethrum Post. 9: 4, 17, 21

It is pointed out that the relative toxicities of pyrethrin I and pyrethrin II to Musca domestica L. reported by various workers show great differences, and it is inferred that these must be at least partly attributable to the instability of the compounds and inadvertent lack of care in handling them.
