Dissipation and Persistence of Certain Insecticides on/in Cowpea Pods (Var. C. 152)

Key Points

• Residual levels of certain foliar insecticides were measured, revealing varied dissipation rates across types.
• Terminal residues of carbofuran and phorate were found at 0.2 ppm and 0.3 ppm respectively, indicating potential health concerns.
• The study focused on various insecticides like endosulfan and chlorpyriphos, with dissipation halflife values ranging from 1.41 to 2.98 days.
• These findings emphasize the need for monitoring insecticide residues on agricultural products to ensure food safety.
