摘要
Root application of certain quaternary ammonium salts, most notably tri‐n‐butyl‐and tri‐n‐pentyl‐4‐chlorobenzylammonium bromides, to wheat seedings grown in water culture enhanced their resistance to powdery mildew Erysiphe graminis but not to brown rust (Puccinia recondita). Anti‐mildew activity was much less apparent if the compounds were applied to sand‐ or soil‐grown seedlings. Systemic activity is considered in relation to the fungitoxicity, phytotoxicity and growth‐retardant activity of these compounds. Copyright © 1979, Wiley Blackwell. All rights reserved
