There is disclosed method of killing nematodes comprising the step of applying an effective amount of a nematicidal composition comprising a terpene component and compositions suitable for use in the method. The terpene component is preferably in association with water, either as a solution or a suspension. An excipient may also be included, which is suitably hollow glucan particles which encapsulate the terpene component.

1. A method of killing plant parasitic nematodes, said method comprising applying an effective amount of a nematicidal composition comprising hollow glucan particles, wherein the hollow glucan particles encapsulate a terpene component comprising a combination of thymol and geraniol, wherein the hollow glucan particles have a lipid content greater than 5% w/w, and wherein the nematicidal composition kills plant parasitic nematodes and wherein the composition comprises a surfactant which holds the terpene component in solution. 2. The method according to claim 1 wherein the nematicidal composition further comprises an excipient. 3. The method according to claim 1 wherein the hollow glucan particles are yeast cell walls or hollow whole glucan particles. 4. The method according to claim 3 wherein the yeast cell walls are derived from Baker's yeast cells. 5. The method according to claim 3 wherein the hollow glucan particles are obtained from the insoluble waste stream of a yeast extract manufacturing process. 6. The method according to claim 3 wherein the glucan particles are alkali extracted. 7. The method according to claim 3 wherein the glucan particles are acid extracted. 8. The method according to claim 1 wherein the hollow glucan particles have a lipid content greater than 10% w/w. 9. The method according to claim 1 wherein the surfactant is selected from the group consisting of sodium lauryl sulphate, polysorbate 20, polysorbate 80, polysorbate 40, polysorbate 60, polyglyceryl ester, polyglyceryl monooleate, decaglyceryl monocaprylate, propylene glycol dicaprilate, triglycerol monostearate, polyoxyethylenesorbitan monooleate, sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan monooleate, polyoxyethylene (4) lauryl ether and mixtures thereof. 10. A method of preparing a composition for killing plant parasitic nematodes, the composition comprising hollow glucan particles encapsulating a terpene component and wherein the terpene component comprises a combination of thymol and geraniol, said method comprising; a) providing the terpene component and a surfactant which holds the terpene component in solution in water;b) providing hollow glucan particles;c) incubating the terpene component with the glucan particles under suitable conditions for terpene encapsulation; andd) recovering the glucan particles encapsulating the terpene component. 11. The method according to claim 10 further comprising the step of drying the glucan particles encapsulating the terpene component. 12. The method according to claim 11 wherein the drying is achieved by freeze drying, fluidized bed drying, drum drying or spray drying. 13. The method according to claim 10 wherein in step a) the terpene component is provided as a suspension in an aqueous solvent. 14. The method according to claim 10 wherein the solvent is water. 15. The method according to claim 10 wherein the surfactant is present at a concentration of 0.1 to 10% by volume of the nematicidal composition. 16. The method according to claim 10 wherein the terpene component is provided as a true solution in water. 17. The method according to claim 10 wherein in step b), the hollow glucan particles are provided as a suspension in a solvent. 18. The method according to claim 17 wherein the suspension comprises 1 to 1000 mg glucan particles per ml. 19. The method according to claim 18 wherein the suspension comprises 200 to 400 mg glucan particles per ml. 20. The method according to claim 10 wherein the hollow glucan particles are provided as a dry powder and added to the terpene-surfactant suspension. 21. The method according to claim 10 wherein the glucan particles are provided in between the hydrodynamic volume and 1.5 times the hydrodynamic volume of water. 22. The method according to claim 11 wherein the conditions of step c) are atmospheric pressure and a temperature of 20 to 37° C. 23. A method of killing plant parasitic nematodes, said method comprising applying an effective amount of a nematicidal composition comprising hollow glucan particles, wherein the hollow glucan particles encapsulate a terpene component and wherein the terpene component comprises a combination of thymol and geraniol, wherein the hollow glucan particles have a lipid content greater than 5% w/w, and wherein the nematicidal composition kills plant parasitic nematodes. 24. A method of killing plant parasitic nematodes, said method comprising: applying an effective amount of a nematicidal composition comprising hollow glucan particles, wherein the hollow glucan particles encapsulate a terpene component comprising a combination of thymol and geraniol, wherein the hollow glucan particles have a lipid content greater than 5% w/w, and wherein the nematicidal composition kills plant parasitic nematodes.
