Abstract
An Evaluation for certain Agricultural candidates against Tuta absoluta on Tomatoes was carried out during two seasons. The determination of the pesticide residues was, also carried out during the course of the study. The obtained results indicated that the traditional insecticides rating in the following order; Voliam flexi (Thiamethoxam
+ Chlorantraniliprole), Avaunt (Indoxacarb) and Coragen (Chlorantraniliprole), are more effective than Bio- insecticides; Proclaim (Emamectin benzoate) followed by Dipel (Bacillus thuringensis var korstaki) and then Achook (Azadirachtin), respectively.
Under open field conditions, the investigation on residual limits and dissipation behavior of some tested insecticides was conducted after the last application. Extraction was carried out using a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for multiclass, multiresidue analysis of pesticides in a variety of matrices. Meanwhile residue determination was performed using Liquid chromatography tandem mass spectrometry (LC.MS.MS). Recoveries were within acceptable levels. Dissipation rates followed the first order kinetics and half-life values for tested insecticides were ranged from 2.3 to 4.53 days and one day for bio- insecticides. According to the Maximum Residue Limits (MRLs) of European Union, the calculated Pre Harvest Intervals (PHIs) of ranged between 2.9 and 8 days for traditional insecticides and between 2.09 and 4.3 days for bio-insecticides.
