Abstract

The invention relates to a plant protection and/or plant growth promotion system, comprising at least one anchor peptide for increased binding to a plant part, a support function, which is indirectly or directly bound to the anchor peptide, and an active substance for protecting the plant and/or promoting plant growth and yield.

Claims

1. A plant protection and/or plant growth promotion system, comprising at least one anchor peptide for increased binding to a plant organ or a plant part, a support function, which is indirectly or directly bound to the anchor peptide, and an active substance for protecting the plant and/or promoting plant growth and/or yield.

2. The plant protection and/or plant growth promotion system according to claim 1, wherein the anchor peptide consists of 2 to 300 amino acids.

3. The plant protection and/or plant growth promotion system according to claim 1, wherein the active substance is selected from the group consisting of:

a pesticide,

an herbicide,

a bactericide,

a fungicide,

a safener

a beneficial organisms,

a means for promoting plant growth and/or colonization of beneficial organisms, and

a plant growth agents.

4. The plant protection and/or plant growth promotion system according to claim 1, wherein the support function is selected from the group consisting of a nanogel, a microgel, a polysome, a polymerosome, a synthosome, a poly-amino acid-spacer, a colloidosome and a cubosome.

5. The plant protection and/or plant growth promotion system according to claim 1, wherein the anchor peptide binds to a leaf, trunk, stem, root, fruit, seed, bud, blossom and/or tuber of a plant.

6. The plant protection and/or plant growth promotion system according to claim 1, wherein the support function is a nano- or microgel and configured such that the active substance either remains on the support function or is directly, time delayed, and/or stimulation dependently released.

7. The plant protection and/or plant growth promotion system according to claim 6, wherein the support function is stimulation dependently released and the stimulus is selected from the group consisting of pH, temperature, humidity, light (including UV light), duration of irradiation, electric pulses, magnetic pulses, elicitors, enzymatic reactions, microbe associated molecular patterns, pathogen associated molecular patterns, damage associated molecular patterns, and herbivore associated molecular patterns.

8. The plant protection and/or plant growth promotion system according to claim 1, wherein the system is a fusion protein.

9. The plant protection and/or plant growth promotion system according to claim 8, wherein the support function is a spacer of 2-100 amino acids.

11. A method for protecting plants and/or promoting plant growth, comprising the following steps:

a) providing a plant protection and/or plant growth promotion system according to claim 1, and

b) applying the plant protection and/or plant growth promotion system onto a plant.

12. The plant protection and/or plant growth promotion system according to claim 2, wherein the support function is selected from the group consisting of a nanogel, a microgel, a polysome, a polymerosome, a synthosome, a poly-amino acid-spacer, a colloidosome and a cubosome.

13. The plant protection and/or plant growth promotion system according to claim 3, wherein the support function is selected from the group consisting of a nanogel, a microgel, a polysome, a polymerosome, a synthosome, a poly-amino acid-spacer, a colloidosome and a cubosome.

14. The plant protection and/or plant growth promotion system according to claim 2, wherein the anchor peptide binds to a leaf, trunk, stem, root, fruit, seed, bud, blossom and/or tuber of a plant.

15. The plant protection and/or plant growth promotion system according to claim 3, wherein the anchor peptide binds to a leaf, trunk, stem, root, fruit, seed, bud, blossom and/or tuber of a plant.

16. The plant protection and/or plant growth promotion system according to claim 4, wherein the anchor peptide binds to a leaf, trunk, stem, root, fruit, seed, bud, blossom and/or tuber of a plant.

17. The plant protection and/or plant growth promotion system according to claim 2, wherein the system is a fusion protein.

18. The plant protection and/or plant growth promotion system according to claim 3, wherein the system is a fusion protein.

19. The plant protection and/or plant growth promotion system according to claim 4, wherein the system is a fusion protein.

20. The plant protection and/or plant growth promotion system according to claim 5, wherein the system is a fusion protein.

21. The plant protection and/or plant growth promotion system according to claim 20, wherein the support function is a spacer of 2-100 amino acids.
