PYRETHRINS JMPR 1974
The 1974 Meeting of the Codex Committee on Pesticide Residues
adopted a temporary tolerance of 3 mg/kg for pyrethrins on peanuts
although no proposal from JMPR was available. It was assumed that this
was an omission as pyrethrins and piperonyl butoxide are usually used
in combination and JMPR had proposed a tolerance for piperonyl
The proposed temporary tolerance for piperonyl butoxide dates
from the 1966 JMPR (FAO/WHO, 1967). In the chapter on piperonyl
butoxide the expression "peanuts and other oil seeds" is used,
resulting in a tolerance proposal of 8 mg/kg for piperonyl butoxide in
these crops. As the post-harvest use of pyrethrins on peanuts is
important and involves the application of 1 mg/kg of pyrethrins, for
which specific analytical methods are now available, the Meeting
recommends a specific tolerance of 1 mg/kg in peanuts. It is further
recommended that the previously proposed temporary tolerances should
be converted to tolerances.
Previously recommended temporary tolerances for pyrethrins should
be confirmed as full tolerances and the following additional tolerance
should be established.
