Terpene-containing compositions and methods of making and using them
View Patent ↗The present invention relates to compositions comprising terpenes and hollow glucan particles or cell wall particles and methods for preparing such compositions. The compositions increase terpene stability and activity and provide a suitable carrier for the terpenes. The invention also relates to methods of using such compositions in the medical, veterinary and agricultural fields.
1. A method of killing mites, said method consisting of:
administering to mites an effective dose a composition consisting of hollow glucan particles or cell wall particles encapsulating a terpene component, wherein the mites infest plants;
wherein the terpene component is thymol; and
wherein the lipid content of the particles is about 5% w/w or greater.
2. The method of claim 1 in which the mites are two-spotted spider mites.
3. The method of claim 1 in which the composition is administered by spraying or otherwise spreading the composition onto the mites.
4. The method of claim 1 in which the composition is administered by spraying or otherwise spreading onto a plant leaf which may then be ingested by the mites.
5. The method of claim 1 in which the composition is administered to an object by immersing the object infested with the mites in the composition.
6. The method of claim 1 in which the composition is administered in the form of a shampoo or the like.
7. The method of claim 1 in which the composition is administered to a fabric infested with mites.
8. The method of claim 7 in which the composition is administered during washing of the fabric.
9. A method of treating or preventing infestation of a plant by mites, said method consisting of:
administering an effective dose of a composition consisting of hollow glucan particles or cell wall particles encapsulating a terpene component to the plant infested by mites or to soil in proximity to the plant,
wherein the terpene component is thymol; and
wherein the lipid content of the particles is about 5% w/w or greater.
10. The method of claim 9 in which the mite is an herbivorous mite.
11. The method of claim 10 in which the herbivorous mite is a two-spotted spider mite.
12. The method of claim 9 in which the composition is administered shortly before harvest of the plant.
13. The method of claim 12 in which the composition is administered 21 days or less prior to harvest.
14. The method of claim 9 in which the composition is administered regularly as a prophylactic measure.
15. The method of claim 9 in which the composition is administered by spraying.
16. A method of killing mites, said method consisting of:
administering to mites an effective dose a composition comprising hollow glucan particles or cell wall particles encapsulating a terpene component,
wherein the mites infest plants;
wherein the terpene component comprises thymol; and
wherein the lipid content of the particles is about 5% w/w or greater.
17. The method of claim 16 , wherein the composition is an acaricide.
18. The method of claim 1 in which the lipid content of the particles is about 10% w/w or greater.
19. The method of claim 9 in which the lipid content of the particles is about 10% w/w or greater.
20. The method of claim 17 in which the lipid content of the particles is about 10% w/w or greater.
21. The method of claim 16 in which the mite is an herbivorous mite.
22. The method of claim 21 in which the herbivorous mite is a two-spotted spider mite.
23. The method of claim 16 in which the composition is administered 21 days or less prior to harvest.
24. The method of claim 16 in which the composition is administered by spraying the mites or by spreading the composition onto the mites.
25. The method of claim 16 in which the composition is administered to a fabric infested with mites.
26. The method of claim 16 in which the composition is administered in the form of a shampoo or the like.
27. The method of claim 16 in which the composition is administered regularly as a prophylactic measure.
28. The method of claim 16 in which the composition is administered to an object by immersing the object infested with the mites in the composition.
29. The method of claim 16 in which the lipid content of the particles is about 10% w/w or greater.
