Persistence of Lambda-cyhalothrin on Pea (Pisum sativum L.)

Thirty five and 70 g a.i. ha⁻¹ of lambda-cyhalothrin was applied to a pea crop, revealed a half life of 4 days. At harvest, the residues on pod cover were 0.10 and 0.25 mg kg⁻¹ from the normal and double the normal dose, respectively, and below detectable limit (<0.002 mg kg⁻¹) in grains.
