Chemical Regulation of Fruit Ripening of Field-Grown Tomatoes with (2-Chloroethyl)phosphonic Acid1

Year: 1971

Type: article

Abstract: Total yield and percentage of ripe tomato fruit were significantly increased following single foliar applications of 0.84 lb. per acre (2-chloroethyl)phosphonic acid (ethephon). Maximum responses were noted at 14 days after treatment. Three tomato cultivars seeded on 3 dates responded similarly. Seventeen days after ethephon application at the 15 percent ripe fruit stage, useable ripe fruit yield was increased to more than 90 percent of the total fruit yield, compared to 59 percent useable ripe fruit for the control. The application of ethephon advanced harvest by 12 to 14 days, with an increase in useable ripe fruit yield of 5 to 10 tons per acre over the optimum potential of the normal ripening rate for single-harvest culture.
