Effciency of Abamectin, 1.8 % EC (Romactin) at different rates (120, 100, 80, 40 and 20 mI/feddan) and its combination with Natural and KZ oils against the leafminer fly (Me(anogromyza phaseoli) on bean plants (Phaseolus vulgans) was evaluated in the Nui plantation, 2003. The experiment was carried out at Etay El Baroud Agricultural Research Station, El-Behera Governorate, Egypt. The results revealed slight significant difference between the tested rates 120, 100 and 80 mI/fed., the efficiencies were 79.6, 69.8 and 66.6% for the three rates, respectively. So, ¡t can be recommended the natural product Romactin at the rate of 80 mI/fed, to control this pest. Regarding the toxicity of tested mixtures, the results indicated that there ¡s no need for adding any Natural oil or KZ oil, where they had no impact on the toxicity of such compound. This in turn minimizes both costs of spray and environmental pollution to protect mans health.
