A survey was carried out in Sardegna (IT) on residues in olive oil from olive treated against Spilocaea oleugina with several systemic fungicides at normal and double dose rate: benomyl, thiophanate‐methyl, bitertanol, penconazole and fenarimol, all currently not registered for this use in Italy. There was a rapid decrease in benomyl, thiophanate‐methyl, and bitertanol in the samples of oil from treated olives collected 0, 10, and 20 days after last treatment, but the degradation of fenarimol appeared slower. In contrast, the concentration of penconazole increased with time. It is suggested that registration of the first four compounds for use on olive would be justified.
