Fruit of apple (Malus domestica Borkh. cv. Golden Delicious) sprayed with triethanolamine salt of silvex [2-(2,4,5-trichlorophenoxy) propionic acid] (2,4,5-TP), a finely dispersed aluminum oxide (Sun Clear), and potassium salt of a fluorochemical carboxylic acid (L-4749) had better finish than controls. Fruit size and seed numbers were significantly reduced by higher rates of 2,4,5-TP. Sprays of a mixture of anion acrylic polymer binding agents (Acrylocoat), poly-l-p-methen-8-9 diyl (Vapor Guard), and a nonionic dimethyl polysiloxane (Dow Corning Silicone 24) increased russeting on ‘Golden Delicious’ apple fruit. Fruit enclosed in a paper bag 16 days after bloom gave a greater reduction in russet than any spray treatment.
Six stores in Southwest Virginia were each visited daily for two weeks in the spring of 1972 to determine rapidity of sale of apples from retail stores. An average of 6.8, 8.5, and 10.5 days were required to sell 95% of bagged, loose, and overwrapped apples, respectively.
