Abstract

Provided is a method for reducing damage by harmful organisms in corn cultivation. Damage by harmful organisms in corn cultivation can be reduced by carrying out the steps of: A) making a furrow in a cultivated land; B) seeding corn into the furrow formed in the foregoing step; C) applying to the furrow one or more selected from the below-mentioned compound group (I) and chlorpyrifos; and D) closing the furrow. compound group (I): group consisting of clothianidin, thiamethoxam, imidacloprid and thiacloprid.

First claim

What is claimed is:

1. A method for reducing damage by harmful organisms in corn cultivation, the method comprising the steps of:
A) making a furrow in a cultivated land; B) seeding corn into the furrow formed in the foregoing step; C) applying to the furrow one or more selected from the below-mentioned compound group (I) and chlorpyrifos; and D) closing the furrow, wherein the steps are performed in a sequential order of A), C), B) and D);
the compound group (I): the group consisting of clothianidin, thiamethoxam, imidacloprid and thiacloprid.

2. The method according to claim 1 , wherein applying one or more selected from the compound group (I) and chlorpyrifos is a step of applying a composition containing the one or more selected from the compound group (I) and a composition containing chlorpyrifos.

3. The method according to claim 2 , wherein the composition containing the one or more selected from the compound group (I) is a granule ormicro-granule containing the one or more selected from the compound group (I).

4. The method according to claim 2 , wherein the composition containing the one or more selected from the compound group (I) is an aqueous dispersion or aqueous solution containing the one or more selected from the compound group (I).

5. The method according to claim 2 , wherein the composition containing chlorpyrifos is a granule or micro-granule containing chlorpyrifos.

6. The method according to claim 2 , wherein the composition containing chlorpyrifos is an aqueous dispersion or aqueous solution of chlorpyrifos.

7. The method according to claim 4 , wherein the aqueous dispersion or aqueous solution is an aqueous dispersion or aqueous solution obtained by dispersing or dissolving in water a water soluble powder, a wettable powder, a water dispersible granule, a soluble concentrate, a microcapsule, an emulsifiable concentrate, a concentrated emulsion, a microemulsion, a suspoemulsion, an oil miscible liquid, a suspension concentrate or a dry flowable which contains the one or more selected from the compound group (I).

8. The method according to claim 6 , wherein the aqueous dispersion or aqueous solution is an aqueous dispersion or aqueous solution obtained by dispersing or dissolving in water a water soluble powder, a wettable powder, a water dispersible granule, a soluble concentrate, a microcapsule, an emulsifiable concentrate, a concentrated emulsion, a microemulsion, a suspoemulsion, an oil miscible liquid, a suspension concentrate or a dry flowable which contains chlorpyrifos.

9. The method according to claim 1 , wherein applying the one or more selected from the compound group (I) and chlorpyrifos is a step of applying a composition containing the one or more selected from the compound group (I) and chlorpyrifos.

10. The method according to claim 9 , wherein the composition containing the one or more selected from the compound group (I) and chlorpyrifos is a granule or micro-granule containing the one or more selected from the compound group (I) and chlorpyrifos.

11. The method according to claim 9 , wherein the composition containing the one or more selected from the compound group (I) and chlorpyrifos is an aqueous dispersion or aqueous solution containing the one or more selected from the compound group (I) and chlorpyrifos.

12. The method according to claim 11 , wherein the aqueous dispersion or aqueous solution is an aqueous dispersion or aqueous solution obtained by dispersing or dissolving in water a water soluble powder, a wettable powder, a water dispersible granule, a soluble concentrate, a microcapsule, an emulsifiable concentrate, a concentrated emulsion, a microemulsion, a suspoemulsion, an oil miscible liquid, a suspension concentrate ora dry flowable which contains the one or more selected from the compound group (I) and chlorpyrifos.

13. The method according to claim 1 , wherein the land is ditched to a depth of 1 to 10 cm.

14. The method according to claim 1 , wherein ditching is performed using a disk furrow opener.

15. The method according to claim 1 , wherein the seeding is performed using a pneumatic seeder.

16. The method according to claim 3 , wherein the composition containing chlorpyrifos is a granule or micro-granule containing the chlorpyrifos.

17. The method according to claim 4 , wherein the composition containing chlorpyrifos is a granule or micro-granule containing the chlorpyrifos.

18. The method according to claim 3 , wherein the composition containing chlorpyrifos is an aqueous dispersion or aqueous solution of the chlorpyrifos.

19. The method according to claim 4 , wherein the composition containing chlorpyrifos is an aqueous dispersion or aqueous solution of the chlorpyrifos.

20. The method according to claim 2 , wherein the land is ditched to a depth of 1 to 10 cm.
