2 - Residues of pirimiphos-methy and profenofos on green pepper and eggplant fruits and their effect on some quality properties
Abstract: The residue levels of two organophosphorus insecticides, pirimiphos-methyl and profenofos in fruits of green pepper and eggplant in relation to their effects on internal quality properties were studied. The results showed that waiting period of 10 and 14 days after application on green pepper and eggplant is enough to reduce the pirimiphos-methyl or profenofos residues, respectively, to below the maximum residue limits (MRL). However, profenofos appeared to have relatively longer persistence with t1/2 of 1.74 and 1.96 days than pirimiphos-methyl with 1.72 and 1.88 days on pepper and eggplant fruits, respectively. As for the internal quality parameters of green pepper, pirimiphos-methyl treated fruit exhibited a significant increase in the total soluble sugars, % dry matter, total protein and ß-carotene content. The profenofos treatment, significantly decreased the total soluble sugars, % dry matter and total protein and has no adverse effect on the % acidity, ascorbic acid and ß-carotene content. Both insecticide residues increased ascorbic acid content and decreased the total soluble sugars, % acidity, T.S.S. in eggplant fruit. Also, the results showed that there were effects of varying degree by both insecticide residues on the levels of fatty acids and amino acids in tested vegetable fruits.
