Abstract

A composition including an ethylene blocking agent complex formed from the product of an ethylene blocking agent and a host, and at least one water-soluble polymer, wherein the ethylene blocking agent complex and the at least one water-soluble polymer are intermingled is disclosed.

Claims

1. A film comprising:

an ethylene blocking agent complex comprising the product of an ethylene blocking agent selected from the group consisting of cyclopropene, 3,3-dimethycyclopropene, methylenecyclopropane and derivatives thereof and a host selected from the group consisting of cyclodextrins and crown ethers; and

at least one water-soluble polymer selected from the group consisting of methylcellulose, propylcellulose, ethylcellulose and hydroxyethylcellulose;

wherein the ethylene blocking agent complex and the at least one water-soluble polymer are intermingled.

2. The composition of claim 1, wherein the ethylene blocking agent comprises 1-methylcyclopropene.

3. The composition of claim 1, further comprising an ethylene generating agent.

4. The composition of claim 1, wherein the molecular encapsulation agent comprises alpha-cyclodextrin.

5. The composition of claim 1, further comprising a water-insoluble polymer.

6. The composition of claim 1, wherein the ethylene blocking agent complex comprises from 0.05 to 0.5 percent by weight ethylene blocking agent.

7. The composition of claim 1, wherein a ratio of water-soluble polymer to ethylene blocking agent complex ranges from 20:

1 to 1 ;

3 by weight.

8. The composition of claim 5, wherein a ratio of water-soluble polymer to water-insoluble polymer ranges from 50:

1 to 1;

50.

9. The composition of claim 1, further comprising at least one of an herbicide, a fungicide, a growth factor, an insecticide, and a fertilizer.

10. The composition of claim 1, further comprising water.
