remaining in/on chili peppers were concentrated by usual
drying process for pepper powder. The reduction factors
reflecting net loss of pesticide residues during drying were
0.50–0.98 for field 1 and 0.44–0.98 for field 2. Drying
caused a large reduction (37–49 %) in clothianidin, diethofencarb,
imidacloprid, and tetraconazole; moderate
reductions (16 and 22 %) in methomyl and methoxyfenozide;
while did not affect the levels of chlorfenapyr,
folpet, and indoxacarb (using conservative higher reduction
factors from the two field trials).
