Abstract
6 surfactants used as additives to pesticide sprays, were applied in aq. sol. to the roots of sorghum plants. After a few h of exposure to the surfactant sol., ions and amino acids leaked from the roots into the ambient sol., presumably due to a loss of membrane integrity. After 2-3 days, the plants wilted and, at high conc. of surfactants, they died. Toxic effects varied with the surfactant and its conc., but no clear relationship was found between the physical effect of lowering the surface tension, the release of solutes by the roots, and the injury caused to the plant. The results are of significance because of the proposed use of sewage effluents, known to contain detergents, for irrigation purposes in Israel.ADDITIONAL ABSTRACT:Six surfactants, used as additives to pesticide sprays, were applied in aq. sol. to the roots of sorghum plants.
