Profenofos residues on and in moloukhia leaves and how to minimize these residues [electronic resource].

Includes references.

These studies were carried out to investigate the residual behaviour of profenofos insecticide on moloukhia leaves Chorchorus olitorius and how to minimize these residues. The initial deposits of profenofos on and in moloukhia leaves was 141.693 ppm, the 3 days following application is critical in the sense of sharply decreases to reach 73.25% from the initial deposit. Also the residue haIf life value (RLso) determined on moloukhia leaves was 38 hours. Washing and drying processes reduced significantlyprofenofos residues in moloukhia leaves. Washing with tap water induced 23.96 to 75.77% removal in total residues of profenofos in moloukhia leaves, whereas it was reached 57.22 to 76.13% with drying process.
