RBF film is a variety of organic and inorganic compounds from the screening and after repeated preparation of a protective and bactericidal properties of the film. After spraying, the tree surface layer can form a layer of film. Tree rot disease effect up to six months or more.Field trial three years of continuous control efficiency of 89%, control the incidence of less than 5% after spraying the film on the growth and development of trees without any adverse effects.
