(WO2016181399) CLAIMS 1. A composition comprising at least one polymer characterized by a surface energy having a value that ranges from 20 mJ/m2to 60 mJ/m2, and an active agent. 2. The composition of claim 1, wherein said active agent is a plant hormone. 3. The composition of any one of claims 1 and 2, wherein said active agent is at a concentration that ranges from 3 mg/L to 30 mg/L. 4. The composition of any one of claims 1 to 3, wherein said polymer is selected from polyvinyl acetate (PVAc), polyvinyl alcohol (PVA), hydroxypropyl cellulose (HPC), hydroxy ethyl cellulose (HEC), and polyvinyl pyrrolidone (PVP), polyethylene, and glycol (PEG), or any combination thereof. 5. The composition of any one of claims 1 to 4, wherein said polymer is HPC. 6. The composition of any one of claims 1 to 4, wherein said polymer is polyvinyl chloride (PVC). 7. The composition of any one of claims 1 to 6, further comprising a plasticizer. 8. The composition of claim 7, wherein said plasticizer is in the range of 30% to 50%, by weight. 9. The composition of any one of claims 7 and 8, wherein said plasticizer is a polymer having a molecular weight (MW) of less than 1000 gr/mole. 10. The composition of claim 9, wherein said plasticizer is PEG. 11. The composition of any one of claims 7 and 8, wherein the plasticizer is glycerin. 12. The composition of any one of claims 7 and 8, wherein said polymer is HPC and the plasticizer is glycerin. 13. The composition of any one of claims 7 and 8, wherein said polymer is PVC and the plasticizer is PEG. 14. An article comprising the composition of any one of claims 1 to 13. 15. The article of claim 14, being a delivery device. 16. The article of claim 15, wherein said device is adapted for installation on a part of a plant, thereby enabling the application of said composition to said plant. 17. The article of any one of claims 15 and 16, wherein the delivery device is configured to wrap the part of the plant. 18. The article of any one of claims 15 to 17, wherein the delivery device has a cylindrical form, a tube form, a ring form or a clamp form. 19. The article of any one of claims 15 to 18, wherein said delivery device is made of a rigid, semi-rigid or a flexible material, or any combinations thereof. 20. The article of any one of claims 15 to 19, wherein the delivery device is made of a biodegradable polymer, composed of pure or blends of bio-plastics. 21. The article of claim 20, wherein the biodegradable polymer comprises or is produced from corn starch, potato starch, agar, gelatin, PLA (polylactic acid) or PLGA (poly(lactic-co- glycolic acid)). 22. The article of any one of claims 16 to 21, wherein the part of the plant is the stem, the bud, the root stock, the trunk, the stalk, or any part of the shoot of said plant. 23. The article of any one of claims 14 to 22, wherein the active agent is a plant hormone being a compound of formula I:  I, wherein: A is an aromatic or non-aromatic 5, 6, or 7 carbon atom membered ring; X is CH¾ H, or NR'; Y is CH2or O; Z is CO or -(4-methyl-5-oxo-2,5-dihydrofuran-2-yloxy)-methylene; Z' is CO or -(4-methyl-5-oxo-2,5-dihydrofuran-2-yloxy)-methylene; R is aryl, heteroaryl, NH2, HR', NR'2, or alkyl; R' is aromatic or heteroaromatic ring or alkyl; or pharmaceutically acceptable salts thereof. The article of claim 23, wherein the plant hormone is a compound of formula II:  II, wherein X is CH2, NH, or NR'; Y is CH2or O; Z is CO or -(4-methyl-5-oxo-2,5-dihydrofuran-2-yloxy)-methylene; Z' is CO or -(4-methyl-5-oxo-2,5-dihydrofuran-2-yloxy)-methylene; R is aryl, heteroaryl, NH¾ NHR', NR'2, or alkyl; R' is aromatic or heteroaromatic ring or alkyl; or pharmaceutically acceptable salts thereof. 25. The article of any one of claims 23 and 24, wherein the compound of formula I is selected from Strigol, Strigyl acetate, Sorgolactone, Orobanchol, Orobanchyl acetate, 5 -Deoxy strigol, 2'-Epiorobanchol, Sorgomol, 7-Oxoorobanchol, Solanacol, Fabacyl acetate, Alectrol, 7- Hydroxyorobanchol, 7-Oxoorobanchyl acetate, and 7 -Hydroxy orobanchyl acetate. 26. The article of any one of claims 23 and 24, wherein the plant hormone is a strigolactone analog, selected from EGO 10, GR24, and ST362. 27. The article of any one of claims 23 to 24, wherein the plant hormone is EGO10, the medium compound is HPC and the plasticizing agent is glycerin. 28. A method for applying a plant hormone to a plant, comprising providing a composition comprising a polymer and a plant hormone formulation or a delivery device adapted to contain said composition, and installing said composition or said delivery device on a part of the plant. 29. The method of claim 28, wherein said plant hormone is provided prior to and/or after the installation of the device. 30. The method according to any one of claims 28 and 29, wherein the plant hormone formulation is provided by filling the device. 31. The method according to any one of claims 28 to 30, further comprising sealing the delivery device containing the plant hormone formulation. 32. The method according to any one of claims 28 to 31, wherein the part of the plant is the stem, the bud, the root stock, the trunk, the stalk, or any part of the shoot of said plant. 33. A composition comprising a natural strigolactone or a strigolactone analog, a polymeric compound, and a plasticizer, for use in decreasing or preventing axillary bud growth in a plant. 34.
