Abstract: Ethephon at 200 mg per l plus 0.25 ml per l of Plus 50 wetting agent resulted in more than 90 percent of the crop dropping consistently within 14 days from Keauhou (246) and Kakea (508) trees. The response by Own Choice trees was more variable. Increasing the concentration of wetting agent to 0.5 ml per l enhanced the effectiveness of ethephon. The practice of applying 200 mg per l ethephon to achieve a single harvest with cultivars 246 and 508 is economically feasible although with Own Choice, because of the high concentration needed for effective drop, the economics are doubtful at this stage. Inexpensive additives which significantly increase the effectiveness of ethephon on Own Choice are required. Leaf drop was not excessive with any of the treatments. |
