| Abstract | ||||
| It well known that there is a clear relation between the Physico-chemical characteristics of used pesticides and their field performance. As a result, the international organizations (FAO and WHO) outlined the tests and specifications that each pesticide must be pass in laboratory before field application. In this study tests were conducted to improve the physico-chemical properties of the IGR atabron 5% EC that was imported, on the account of the Ministry of Agriculture in 2005 but it failed in laboratory tests. These treatments were carried out by using locally available additives as organic solvents and surface active agents. We found that emulsifier (Tween 80) or its mixture with the polar solvent DMF highly improved the Physico-chemical characteristics of the insecticide. Field performance evaluation was carried out for the reworked and non-reworked formulations in the season of 2007. The data obtained revealed that the selected two methods of treatment clearly improved the insecticidal activity under field conditions. | ||||
