Abstract: (2-Chloroethyl)phosphonic acid (ethephon) was applied to Red Kidney beans ( Phaseolus vulgaris L. cv. California Light Red) at rates of 0.14 to 0.56 kg/ha to determine its effectiveness in defoliating the plants and conditioning them for harvest, without a reduction in yield. Ethephon (0.14 kg/ha) reduced yield of beans 25% when applied 18 days before the normal harvest date, but when applied 7 days before the normal harvest date no yield reduction occurred even at high rates; and low rates produced 90% defoliation. When temperatures were 10°C or below, poor defoliation occurred even at high rates of ethephon. Surfactants with ethephon did not affect defoliation or yield.
