Summary. Several alkylphenol ethylene oxide ether non-ionic surfactants were tested in aqueous foliar sprays with dalapon, amitrole and paraquat for (heir enhancement of phytocidal activity against Zea mays L. With three homologous series of surfactants studied (octyl-, nonyl- and laurylphenol types), the herbicide, the surfactant concentration and the hydrophilic constitution (ethylene oxide content) of the surfactant molecule all markedly influenced maximum toxicity. Smaller apparent differences in effectiveness were also attributable to the hydrophobic (alkylphenol) portion of the surfactant. The results arc discussed in relation to possible cuticle-spray solution interactions and their influence on herbicide penetration.Relations entre la structure et l'activite de produits tensio-actifs non ionigues, a base d'éther d'oxyde éthylénique et d'alkylphénol, en présence de trois herbicides hydrosolubles
