Abstract | ||||
Two type of surface active agents anionic and nonionic were prepared from locally raw materials: Fatty acids (Oleic and Stearic acid) reacted with PEG 400. 600 in case of preparation nonionic surfactants and fatty acids reacted with potassium hydroxide and calcium oxide in case of preparation anionic surfactants. Locally prepared nonionic surfactants were identified using lit and Mass spectroscopy. Physico-chemical properties were assessed such as solubility in different solvents, surface tension and pH value. Experiments were conducted to evaluate the pesticidal efficiency of those prepared surfactants to use it as alternatives instead of some conventional pesticides against sucking pierce pests infested common bean. Results obtained indicated that the prepared surfactants were effective at concentrations 1.0 and 1.5% in their initial and residual effect against: egg of whitefly and moving stages of spider mite. | ||||
