Compositions with cyclopropenes and metal-complexing agents
View Patent ↗A composition is provided that contains a cyclopropene and a metal-complexing agent. Also provided is a method that includes contacting such compositions to plants or plant parts.
1. A sprayable liquid composition comprising:
at least one cyclopropene of the formula (1)
wherein R is selected from the group consisting of hydrogen, an unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, phenyl, or naphthyl group, and a substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, phenyl, or naphthyl group having as a substitutent a halogen, alkoxy, substituted phenoxy, or unsubstituted phenoxy group;
at least molecular encapsulating agent that encapsulates the cyclopropene;
at least one metal complexing agent selected from the group consisting of ethylenediaminetetraacetic acid (EDTA), hydroxyethylethylenediaminetriacetic acid, nitrilotriacetic acid, N-dihydroxyethylglycine, and ethylenebis(hydroxyphenylglycine); and
water.
2. The liquid composition of claim 1 , wherein the metal complexing agent is EDTA.
3. The liquid composition of claim 2 , wherein the composition further comprises an alkaline carbonate.
4. The liquid composition of claim 3 , wherein the alkaline carbonate is sodium carbonate.
5. A method for blocking the effects of ethylene or plant part, the method comprising contacting the liquid composition of claim 1 to the plant or plant part.
6. The method according to claim 5 , wherein contacting the liquid composition to the plant or plant part comprises spraying, foaming, fogging, pouring, brushing, or dipping.
7. The method according to claim 6 , wherein contacting the liquid composition to the plant or plant part comprises dipping.
8. The method according to claim 6 , wherein contacting the liquid composition to the plant or plant part comprises spraying.
9. The liquid composition of claim 1 , wherein the amount of the cyclopropene(s) in the composition is between 1 ppb and 1,000 ppm.
10. The liquid composition of claim 1 , wherein the metal complexing agent is in a complex with one or more metal ions.
11. A method for blocking the effects of ethylene in a plant or plant part, the method comprising:
contacting the liquid composition of claim 9 to the plant or plant part.
12. The liquid composition of claim 9 , wherein the metal complexing agent is in a complex with one or more metal ions.
13. The liquid composition of claim 10 , wherein the composition comprises metal complexing agent in a complex with iron ions.
14. The liquid composition of claim 10 , wherein the composition comprises metal complexing agent in a complex copper ions.
15. The method according to claim 6 , wherein contacting the composition to the plant or plant part comprises spraying and dipping.
16. The method according to claim 5 , wherein contacting the composition to the plant or plant part is performed in a ventilated area.
17. A method for blocking the effects of ethylene in a plant or plant part, the method comprising:
contacting the liquid composition of claim 10 to the plant or plant part.
18. A method for blocking the effects of ethylene in a plant or plant part, the method comprising:
contacting the liquid composition of claim 12 to the plant or plant part.
19. The method according to claim 5 , wherein when contacting the liquid composition to the plant or plant part, cyclopropene is released from the molecular encapsulating agent in an amount greater than is released upon contact with a plant or plant part of an otherwise identical composition that does not comprise the metal complexing agent.
20. The method according to claim 5 , wherein substantially all of the cyclopropene is released from the molecular encapsulating agent when the liquid composition contacts the plant or plant part.
21. The liquid composition of claim 1 , wherein the metal complexing agent is present in an amount of 1% by weight or less of the composition.
22. The liquid composition of claim 1 , wherein the metal complexing agent is present in an amount of 0.01% by weight or more of the composition.
