| Abstract | ||||
| A field experiment was conducted in Assiut Governorate during the winter seasons of 2006/07 and 2007/08 to evaluate some natural compound (Vertemic 1.8, RM 131, Super-Misrona oil, Potassium solution and Micro-elements) in addition to fintera thion as a conventional acaricide for controlling sucking pests infesting faba bean. The obtained data revealed that all tested materials were significantly effective against A. craccivera and T. urticae compared to the untreated plots (control). In both seasons vertimec and super-misrona were the most potent compounds in reducing the population size of A. craccivera at the initial kill with reduction% of 85 and 84, respectively, followed by RM131 with reduction % of 75.5. Potassium and micro-nutrients were the least effective one (43 reduction %). The efficiency of sprayed materials (potassium or micro-nutrienta) increased as the time proceeds. Also, in both seasons, vertimec and super-misrona were the most potent compounds in reducing the population size of T. urticae at the initial kill with reduction % of almost 87.5 and 85 %, respectively, followed by RM131 with reduction % of almost 81.5 %. Potassium and micro-nutrients were the least effective one (almost 76 and 71.5% reduction, respectively). The used natural products were more effective in reducing the population number of T. urticae than that of A. craccivera. The residual effect % followed the previous trend and could be arranged in descending order of vertimec > super-misrona > RM131 > potassium > micro-nutrients. | ||||
