‘Royal Gala’, ‘Ultra Gold’, and ‘Blushing Golden’ on M7A were treated two years with Wilthin (monocarbamide dihydrogensulfate) at 0 ml•l -1, 5 ml•l -1, 10 Ml•l -1and 15 ml•l -1when trees were at 70 to 80 percent bloom. Wilthin at 5 ml•l -1and 15 ml•l -1resulted in satisfactory thinning of all cultivars. Yield was not affected as a result of thinning with Wilthin. Fruit weight and size were increased, firmness and individual sugars were increased, acidity was reduced, and juice pH was increased as a result of thinning with Wilthin.
