Delivery of ethylene blocking and/or promoting agents
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.
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.
