The effectiveness of a number of film-forming chemicals was evaluted in three field experiments for protecting fruit and landscape trees against salt spray injury and in reducing Na and Cl ion buildup in the twigs. In separate experiments, Folicote, Joncryl 1938, RD 1725, RD 1726, and Siliconate 51T were evaluated on peach trees and red pine. The spray treatments reduced peach twig injury to a limited degree and reduce Ca ion accumulation by 18-30%. Covering the tree branches with burlap resulted in the least injury and salt accumulation. In the pine trees, the spray treatments resulted in small reductions in injury to the red pine twigs. Except for the Siliconate 51T treatment, all spray treatments reduced salt accumulation as compared to untreatment twigs. In an additional study, Foliconate, RD 1725, RD 2033, RD 2035, and RD 2036 were evaluated on whole peach trees that were sprayed four times during the winter of 1987 with 2% rock salt solution. RD 2033 treated twigs had the least injury and accumulated moderately less Cl ion than untreated twigs. All other treatments were ineffective in reducing injury and salt buildup. (Author/TRRL)
