Farmers stock peanuts containing either 0% loose-shelled kernels (LSK) and 0% foreign material (FM), 5% LSK-10% FM, or 10% LSK-20 FM were sprayed with 20% PPM pirimiphos-methyl. Peanut samples were analyzed for insecticide residues during a 1-year storage period. Significantly lower residues were found on in-shell peanuts with 0% LSK-FM than on either of the 2 LSK-FM combinations. Insecticide residues accumulated in the FM and to a lesser extent in the LSK. Negligible residues were found on sound mature kernels from solid pods.
