An agricultural item comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units. The first randomly repeating monomer unit has the structure: wherein R1 is H or a C1-2 alkyl, and n is 1 or 2; and the second randomly repeating monomer unit has the structure: wherein R2 is a C3-19 alkyl or a C3-19 alkenyl. At least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.

1. An agricultural item comprising an anaerobically biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure: wherein R1 is H or a C1-2 alkyl, and n is 1; and the second randomly repeating monomer unit has the structure: wherein R2 is a C3-19 alkyl or a C3-19 alkenyl; wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit; and wherein the agricultural item is selected from the group consisting of erosion control covers, nets, pots, wreath rings, mulches, plant stakes, labels, twines, ropes, seed-containing devices, chemical-containing devices, encapsulated seeds, encapsulated chemicals, plant coatings and mixtures thereof and wherein said anaerobically biodegradable polyhydroxyalkanoate copolymer is non-brittle and has a melting temperature from about 60 C to about 140 C.2. An agricultural item according to claim 1, wherein the anaerobically biodegradable plastic further comprises a third randomly repeating monomer unit having the structure: wherein R3 is H, a C1-19 alkyl or a C1-19 alkenyl, and m is 1; and wherein the additional randomly repeating monomer unit is not the same as the first randomly repeating monomer unit or the second randomly repeating monomer unit.3. An agricultural item according to claim 1, wherein R1 is a C1-2 alkyl and n is 1.4. An agricultural item according to claim 1, wherein R1 is a C1 alkyl.5. An agricultural item according to claim 1, wherein R1 is H and n is 2.6. An agricultural item according to claim 1, where the item is substantially free of plasticizers.7. An agricultural item according to claim 6, wherein the chemical is selected from fertilizers, pesticides, herbicides, compounds which are unpalatable to animals, compounds which are attractant to beneficial insects and mixtures thereof.8. A method of treating a plant comprising the step of contacting at least a portion of a plant with a composition comprising an anaerobically biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure: wherein R1 is H or a C1-2 alkyl, and n is 1; and the second randomly repeating monomer unit has the structure: wherein R2 is a C3-19 alkyl or a C3-19 alkenyl; wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit and wherein said anaerobically biodegradable polyhydroxyalkanoate copolymer is non-brittle and has a melting temperature from about 60 C to about 140 C.9. A method according to claim 8, wherein the anaerobically biodegradable plastic further comprises a third randomly repeating monomer unit having the structure: wherein R3 is H, a C1-19 alkyl or a C1-19 alkenyl, and m is 1; and wherein the additional randomly repeating monomer unit is not the same as the first randomly repeating monomer unit or the second randomly repeating monomer unit.10. A method according to claim 8, wherein the plant is a cut flower.11. A method according to claim 8, wherein the step of contacting the plants comprises contacting leaves with the composition, and wherein moisture loss by the leaves is decreased.12. A method according to claim 8, wherein the plant is protected from a pest selected from plant pathogens, arachnids, insects, animals, weeds and mixtures thereof.13. A method according to claim 8, wherein the composition further comprises an ingredient selected from the group consisting of pesticides, herbicides, fungicides, mildewcides and mixtures thereof.14. A method according to claim 8, wherein the composition further comprises an ingredient unpalatable to animals.15. A method for the controlled release of a chemical comprising treating the chemical with an anaerobically biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure: wherein R1 is H or a C1-2 alkyl, and n is 1; and the second randomly repeating monomer unit has the structure: wherein R2 is a C3-19 alkyl or a C3-19 alkenyl; and wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit and wherein said anaerobically biodegradable polyhydroxyalkanoate copolymer is non-brittle and has a melting temperature from about 60 C to about 140 C.16. A method according to claim 15, wherein the anaerobically biodegradable plastic further comprises a third randomly repeating monomer unit having the structure: wherein R3 is H, a C1-19 alkyl or a C1-19 alkenyl, and m is 1; and wherein the additional randomly repeating monomer unit is not the same as the first randomly repeating monomer unit or the second randomly repeating monomer unit.17. A method according to claim 15, wherein step of treating the chemical comprises coating the chemical with the biodegradable polyhydroxyalkanoate copolymer.18. A method according to claim 15, wherein step of treating the chemical comprises incorporating the chemical into a device comprising the biodegradable polyhydroxyalkanoate copolymer.19. A method according to claim 15, wherein R1 is a C1-2 alkyl and n is 1.20. A method according to claim 18, wherein R1 is a C1 alkyl.
