Abstract: Antitranspirant sprays of 5 film-forming materials were compared on mature Citrus sinensis (L.) Osbeck cv. Valencia trees for film persistence and reduction of fruit weight loss after harvest. These materials were also sprayed on young ‘Pineapple’ ( C. sinensis ) or ‘Valencia’ orange trees growing in 7.6 liter containers on which weight loss was subsequently measured for 48-hour periods after watering. Spray solutions of equal or known film-forming ingredients (solids content) of 1 to 4% (weight/weight) were applied and compared. Plantgard film did not significantly increase the leaf epicuticular coating nor did it reduce fruit weight loss or young tree water use. Mobileaf, Vapor Gard, Nu-Film-17, and Wilt Pruf NCF did result in heavier leaf coatings and less fruit weight loss than the controls. Mobileaf and Vapor Gard reduced potted tree water use. Some loss of effectiveness and coating thickness occurred 5 months after application, but only a small nonsignificant change in effectiveness occurred during the first 2 months after application. Mobileaf and Vapor Gard appeared to give the best antitranspirant protection for the initial 2 months and Vapor Gard for 5 months.
