Abstract

Formulations containing anthraquinone derivatives with increased effectiveness as pesticides are provided. These formulations may comprise (a) a preparation comprising one or more anthraquinone derivatives having activity against plant pests; (b) one or more C2-C7 alcohols, or glycols or lactones; and (c) one or more surfactants selected from the group consisting of a sulfate, ethoxylated fatty acid esters wherein said alcohols and surfactants are present in amounts effective to stability said preparation. Also provided are methods of using these formulations as pesticides.

First claim

What is claimed is:

1. A formulation comprising
(a) a preparation comprising 0.01% to 45% by weight of a root extract derived from a root of Reynoutria sachalinensis , wherein said root extract comprises physcion, chrysophanol, and emodin in amounts effective to induce plant resistance to phytopathogens;
(b) 0.1% to 15% anti-microbial agent; and
(c) 0.1% to 50% by weight of one or more surfactants selected from a sulfate and ethoxylated fatty acid ester to stabilize said preparation.

2. The formulation according to claim 1 , wherein said anti-microbial agent is 2% to 10% by weight and said surfactant is 0.01% to 15% by weight sodium lauryl sulfate, 0.1% to 35% by weight 2-[2-[3,4-bis(2-methoxyethoxy)oxolan-2-yl]-2-(2-methoxyethoxy)ethoxy]ethyl hexadecanoate or both.

3. The formulation according to claim 1 , further comprising an alcohol or diol comprising 2-7 carbons wherein said alcohol or diol is selected from ethanol, isopropanol, butanol, hexanol, ethylene glycol and propylene glycol.

4. The formulation according to claim 1 , further comprising 0.1% to 8% by weight propylene glycol.

5. The formulation according to claim 1 , wherein
said root extract is 1% to 30% by weight;
said anti-microbial agent is 2% to 10% by weight;
said surfactant is 0.01% to 15% by weight sodium lauryl sulfate; and
10% to 40% by weight 2-[2-[3,4-bis(2-methoxyethoxy)oxolan-2-yl]-2-(2-methoxyethoxy)ethoxy]ethyl hexadecanoate.

6. The formulation of claim 1 , further comprising at least one of (i) an antifreeze, (ii) a carrier or (iii) an antimicrobial agent having at least one of: fungicidal or insecticidal activity.

7. The formulation of claim 1 , further comprising 2% to 10% by weight of an antimicrobial agent and 1% to 8% by weight of an anti-freeze selected from propylene glycol.

8. The formulation of claim 1 , wherein the surfactant is 2-[2-[3,4-bis(2-methoxyethoxy)oxolan-2-yl]-2-(2-methoxyethoxy)ethoxy]ethyl hexadecanoate and sodium lauryl sulfate.

9. The formulation of claim 1 , wherein the formulation is a liquid formulation.

10. The formulation of claim 1 , wherein said preparation comprises
1% to 30% by weight said root extract of Reynoutria sachalinensis;
said one or more surfactants are 0.01% to 15% by weight sodium lauryl sulfate and 0.1% to 35% by weight 2-[2-[3,4-bis(2-methoxyethoxy)oxolan-2-yl]-2-(2-methoxyethoxy)ethoxy]ethyl hexadecanoate; and
said anti-microbial agent is 2% to 10% by weight; and
further comprises 1% to 8% by weight propylene glycol.

11. The formulation of claim 1 , wherein the formulation is a micro emulsion.

12. The formulation of claim 11 ,
further comprising hexanol in the amount of 0.1% to 10% by weight.

13. The formulation of claim 1 , further comprising an anti-freeze agent in an amount of 2% to 8% by weight.

14. A formulation comprising:
a preparation comprising 1% to 30% by weight of a root extract derived from a root of Reynoutria sachalinensis that induces a plant resistance to powdery mildew, wherein said plant root extract comprises physcion, chrysophanol, and emodin;
0.1% to 15% by weight of an antifreeze having 2 to 7 carbons;
0.1% to 15% by weight of sorbate salt; and
10% to 40% by weight of one or more surfactants in amounts effective to stabilize said preparation selected from a sulfate and ethoxylated fatty acid ester.

15. The formulation of claim 14 , wherein said antifreeze is propylene glycol.

16. The formulation of claim 15 , further comprising an antifoaming agent, a carrier and an antimicrobial agent wherein said antimicrobial agent is selected from the group consisting of a chemical pesticide, biopesticide or natural or oil-product having fungicidal activity.

17. A formulation that induces a plant resistance to phytopathogens comprising
a preparation comprising
1% to 30% by weight of a root extract comprising physcion, chrysophanol, and emodin that induces a plant resistance to phytopathogens derived from a root of Reynoutria sachalinensis;
0.1% to 8% by weight of propylene glycol;
0.1% to 15% by weight of sorbate salt;
0.01% to 15% by weight sodium lauryl sulfate;
0.1% to 35% by weight 2-[2-[3,4-bis(2-methoxyethoxy)oxolan-2-yl]-2-(2-methoxyethoxy)ethoxy]ethyl hexadecanoate; and

an antifoaming agent; and
disposed in a carrier.

18. The formulation of claim 17 , further comprising an antimicrobial agent wherein said antimicrobial agent is selected from the group consisting of a chemical pesticide, biopesticide or natural or oil-product having fungicidal activity.

19. A formulation comprising
(a) a preparation comprising 0.01% to 45% by weight of a root extract derived from Reynoutria sachalinensis , wherein said root extract comprises physcion, chrysophanol, and emodin in amounts effective to induce plant resistance to phytopathogens; and
(b) 0.1% to 50% by weight of one or more surfactants selected from a sulfate and ethoxylated fatty acid ester to stabilize said preparation.

20. A method for reducing a fungal infection in a plant comprising the steps of:
providing a plant having a fungal infection, wherein the fungal infection is powdery mildew;
applying the formulation of claim 1 to the plant in an amount effective to reduce said fungal infection.
