Abstract

Two different experiments were carried out to evaluate the pesti­cidal efficiency of some inorganic salts contained toxic moiety in its molecules against sucking pests infesting Phaseolous vulgaris. The first experiment was done in pots at salt concentrations 0.05, 0.2 and 0.8%, while the second experiment was carried out in open field at 0.2% of each salt. The tested salts were: ammonium floride. barium nitrate, sodi­um phosphite and potassium bromate. Results obtained Indicated that concentration of 0.2% of each salt was suitable for controlling spider mite: Tetranychus urticae, aphis: Aphis gossypit and jasside: Empoasca lybica without any phytotoxic effect against Phaseolous vulgaris seed­lings.
