Abstract

AbstractThis innovative study was carried out to determine the presence of the mineral oil Arbofine in apple and soil at four locations. Arbofine kills the vast majority of dormant insects and mites (mite and asphid eggs, scales and psyllids) on fruit trees (cherry, apple, plum and peach) and thus reduces the plant diseases in summer. In this study, the mineral oil was sprayed at recommended doses of 2.0 and 0.75%, and the doses were doubled to 4.0 and 1.5% in dormant and summer seasons, respectively. The soil samples were taken for observation during the dormant season, whereas both soil and apple samples were taken during the summer season after treatment for 0, 1, 3 and 5 days. The recovery study of all the 11 paraffinic constituents (n‐pentane, n‐hexane, n‐heptane, n‐octane, n‐nonane, n‐decane, n‐undecane, n‐dodecane, n‐tridecane, n‐tetradecane and n‐pentadecane) in soil and apple samples which constitutes 60% of mineral oil in soil and apple was carried out at the fortification level of 1.0 μg/ml, which was found to be between 72.1% and 99.0%. No residue of all the 11 paraffinic compounds of Arbofine mineral oil was detected in soil and apple samples at day 0 after the recommended doses, and the recommended doses were doubled in both seasons at four locations. Therefore, mineral oil can be used on apples without any risk.
