The present study wascarried out at a private farm cultivated with garden\ bean (Phaseolus vulgaris) var.

Nepraska during the subsequent Neely seasons of 2014, 2015 and 2016 to control the leafminer, liromyza trifolii Burg at El-Nahada region, Alexandria Governorate, Egypt.

In the first season of 2014, Chlorantraniliprole and Abamectin were the most effective treatments against the leafminer, liromyza trifolii Burg corresponding to percent reduction of 90.98 and 64.04, followed by Acetampride 55.60% and Thiamethoxam- 48.30%.

The least effective agrochemicals were Lambda cyhalothrin- 27.96%, Azadirachtin- 25.55% and Detergent- 12.58%.

On 2015 season, the data comfirmed that the most efficient Chlorantraniliprole 77.07% and Abamectin 64.13% followed by Acetampride and Thiamethoxam 48.56% and 38.94%, in successively.

The least effective agrochemicals were Azadirachtin 29.18%, Lambda cyhalothrin 24.71% and Detergent 9.32%, respectively.

On 2016 season, the IPM model showed that the best treatment was abamectin followed by acetamprid, chlorantraniliprole and thiamethoxam while the least treatments were lambda cyhalothrin, azadirachtin and detergent.
