Defoliation of Snap Beans with Preharvest Treatments of 2-Chloroethylphosphonic Acid1

Year: 1970

Type: article

Abstract: 2-chloroethylphosphonic acid (Ethrel) applied to snap bean plants (cv. ‘Tenderette’) at 250-4000 ppm as a preharvest treatment caused considerable leaf abscission. A reduction in yield per plant resulted from yellowing and abscission of the pods. Much less damage occurred with the lower concentrations and/or by postponing the treatment close to the anticipated harvest time. The effectiveness of Ethrel as a leaf abscission promotor was greater in the summer than in the autumn season. The possible use of Ethrel as an aid for mechanical harvesting of snap beans is discussed.
