Residue behaviour of fenvalerate, tau-fluvialinate, lambda-cyhalothrin and monocrotophos in eggplant (Solanum melongena L.) fruits
1992
Mukherjee, I. | Gopal, M.
The persistence patterns of three synthetic pyrethroids-fenvalerate, tau-fluvalinate, lambda-cyhalothrin-- and an organophosphorus insecticide, monocrotophos, on eggplant (Solanum melongena L.) have been evaluated. The extractable residues ranged from 0.05 to 0.45, 0.01 to 0.40, 0.003 to 0.09 and 0.09 to 0.32 microgram g-1 for fenvalerate, tau-fluvalinate, lambda-cyhalothrin and monocrotophos, respectively. Fenvalerate was the most persistent among the four, followed by monocrotophos. lambda-cyhalothrin and tau-fluvalinate. The Maximum Residue Limit (MRL) of these pesticides on S. melongena has not yet been documented. The present data may be useful for establishing MRL and assessing the amount of pesticide residues in this vegetable.
