Abstract

Coating composition for applying to monocot plant structures from which roots and shoots are capable of growing, wherein the said coating composition comprises one or more organic materials having a melting point of ≧50° Centigrade and one or more additives, methods of making such compositions and coated monocot plant structures such as seeds of monocot plants.

Claims

1-24. -24. (canceled)

25. A coating composition in particulate form for a monocot plant structure, comprising:

i) at least one organic material selected from waxes having a melting point of ≧

50°

Centigrade, wherein the wax is in the form of particles having a volume mean diameter ≧

5 μ

m; and

ii) at least one additive for enhancing at least one of seedling vigour and seedling growth from monocot plant structures, wherein the at least one additive is selected from at least one of an inorganic additive and a live biological agent

26. A coating composition according to claim 25, wherein the particles have a volume mean diameter in the range of 10 to 200 μ

m.

27. The coating composition according to claim 25, wherein the organic material is selected from carnauba wax, beeswax, montan wax, Chinese wax, shellac wax, spermaceti wax, myricyl palmitate, cetyl palmitate, candelilla wax, castor wax, ouricury wax and rice bran wax or is a mixture of two or more thereof.

28. Use of an organic material in the form of particles of wax having a melting point of ≧

50°

Centigrade in the manufacture of a composition for coating monocot plant structures according to claim 25.

29. Use according to claim 28, wherein the wax is selected from carnauba wax, beeswax, montan wax, Chinese wax, shellac wax, spermaceti wax, candelilla wax, castor wax, ouricury wax and rice bran wax or is a mixture of two or more thereof.

30. A method of manufacturing a monocot plant structure coating composition according to claim 25 that comprises:

1) selecting a solid organic material, wherein the solid organic material is wax having a melting point of ≧

50°

Centigrade;

2) machining said organic material into particles of a volume mean diameter ≧

10 μ

m; and

3) adding at least one additive for enhancing at least one of seedling vigour and seedling growth from monocot plant structures, wherein the at least one additive is selected from at least one of an inorganic additive and a live biological agent.

31. The method according to claim 30, wherein the organic material is selected from carnauba wax, beeswax, montan wax, Chinese wax, shellac wax, spermaceti wax, candelilla wax, castor wax, ouricury wax, and rice bran wax;

or a mixture of two or more thereof.

32. The coating composition according to claim 25, wherein the monocot plant structure is selected from monocot plant seeds selected from Oryza spp., Triticum spp., Secale spp., Avena spp., Zea spp., Sorghum spp., Hordeum spp. and seeds of hybrid crosses of monotcotyledonous plants.

33. The coating composition according to claim 25, wherein the monocot plant structures are monocot plant seeds are selected from Oryza sativa, T. aestivum, Secale cereale, Avena sativa, Zea mays, Sorghum bicolor, Hordeum vulgare and x Triticosecale.

38. Monocot plant structures comprising a coating composition according to claim 25.

39. Monocot plant structures comprising a coating composition according to claim 25 that are selected from coated seeds and coated bulbs.

40. Monocot plant structures comprising a coating composition according to claim 25 that are monocot seeds.

41. Monocot plant structures according to claim 39 that are selected from monocot plant seeds selected from Oryza spp., Triticum spp., Secale spp., Avena spp., Zea spp., Sorghum spp., Hordeum spp. and seeds of hybrid crosses of monotcotyledonous plants.

42. Monocot plant structures according to claim 39 that are selected from monocot plant seeds selected from Oryza sativa, T. aestivum, Secale cereale, Avena sativa, Zea mays, Sorghum bicolor, Hordeum vulgare and x Triticosecale.

34. A method of coating monocot plant structures with a coating composition in dry particulate form that comprises at least one organic material selected from waxes having a melting point of ≧

50°

Centigrade, the method comprising;

i) providing particles of the organic material admixed with at least one additive for enhancing at least one of seedling vigour and seedling growth from monocot plant structures, the at least one additive being selected from at least one of an organic additive and a live biological agent and the particles being of a predetermined volume mean diameter; and

ii) applying the particles admixed with the at least one additive to monocot plant structures.

35. The method according to claim 34, wherein the organic material is selected from carnauba wax, beeswax, montan wax, Chinese wax, shellac wax, spermaceti wax, candelilla wax, castor wax, ouricury wax, and rice bran wax or is a mixture of two or more thereof.
