It was found that various organic materials are attracted into urea canal by hexanedioldiacrylate (HDDA) and long chain compounds. This means that materials which does not form complex byitself are induced in canal by (HDDA) and long chain compounds. To include with stability perfumes, insecticides,attractants and repellents in urea canal, leaf was used as model compound for guest molecules in thecanal. The leaf alcohol from the canal released gradually over many days and the release was inhibited for 15days by long chain compounds and for 30 days by polymerized HDDA after irradiation. After releasing, theleaf alcohol in the canal remained 25% stable for long chain compounds and 40% for polymerized HDDAThe dose required for stabilization of leaf alcohol in the urea canal by canal polymerization of HDDA was 30.
