PREPARATION OF SOME SURFACE ACTIVE AGENTS AND EVALUATION OF IT'S PESTTCIDAL EFICIENCY AGAINST SUCKING PIERCE PESTS INFESTING COMMON BEAN
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.
