A method for estimating leaf compartmentalization of pesticides in citrus


, : A method for estimating leaf compartmentalization of pesticides in citrus. Journal of Agricultural & Food Chemistry 29(4): 750-756

A method for estimating surface, wax and cellular pesticide residues of the citrus leaf is presented. EM showed little alcohol penetration of the cell in a short surface strip. Methanol compared with the dislodgeable surface strip as a wax solvent. Chloroform was the most efficient wax solvent, penetrated to the cell, but left the cell membrane intact. Parathion in methanol did not partition into leaf wax or cell, whereas 27% leaf partitioning occurred with the dislodgeable solvent. Low percentages of systemic acephate were removed with a methanol surface strip or a chloroform wax strip. The final method consists of a 1-min methanol surface strip, a 1-min chloroform wax strip and a final analysis of penetrated residues.
