Claims
- 1. An insect repelling/killing film made according to the process comprising preparing a clathrate compound of fenitrothion in cyclodextrin, drying the clathrate compound, granulating the dried clathrate compound into a dry powder, mixing the melting the dry powder and a synthetic resin material in a weight ratio of clathrate compound to synthetic resin material ranging from 0.1 to 4%, molding the molten mixture into pellets and molding the pellets into a film.
- 2. An insect repelling/killing film as in claim 1, wherein the synthetic resin material is selected from the group consisting of olefin plastic, soft vinyl chloride plastic and vinyl acetate plastic.
- 3. An insect repelling/killing film as in claim 1, wherein the synthetic resin material has a molding temperature lower than the decomposition temperature of fenitrothion.
- 4. An insect repelling/killing film as in claim 1, wherein the clathrate compound is homogeneously dispersed in the synthetic resin material.
- 5. An insect repelling/killing film as in claim 1, further comprising a second synthetic resin material.
- 6. An insect repelling/killing film as in claim 5, wherein the second synthetic resin material is a polyethylene plastic.
- 7. An insect repelling/killing film made according to the process comprising preparing a clathrate compound of fenitrothion in a starch decomposition product containing cyclodextrin, drying the clathrate compound, granulating the dried clathrate compound into a dry powder, mixing and melting the dry powder with a synthetic resin material in a weight ratio of clathrate compound to synthetic resin material ranging from 0.1 to 4%, molding the molten mixture into pellets and molding the pellets into a film.
- 8. An insect repelling/killing film as in claim 7, wherein the synthetic resin material is selected from the group consisting of olefin plastic, soft vinyl chloride plastic, vinyl acetate plastic and polyethylene plastic.
- 9. An insect repelling/killing film as in claim 7, wherein the synthetic resin material has a molding temperature lower than the decomposition temperature of fenitrothion.
- 10. An insect repelling/killing film as in claim 7, wherein the clathrate compound is homogeneously dispersed in the synthetic resin material.
- 11. An insect repelling/killing film as in claim 7, further comprising a second synthetic resin material.
- 12. An insect repelling/killing film as in claim 11, wherein the second synthetic resin material is a polyethylene plastic.
