Abstract

The present invention provides a Tylenchoidea plant parasitic nematode control agent comprising: at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), a compound represented by the following formula (3), enantiomers thereof, and agriculturally and horticulturally acceptable acid addition salts thereof as an active ingredient

Claims (18)

1. A method for controlling a Tylenchoidea plant parasitic nematode, comprising:

treating a target with an effective amount of at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), enantiomers thereof, and agriculturally and horticulturally acceptable acid addition salts thereof

wherein the Tylenchoidea plant parasitic nematode is at least one plant parasitic nematode selected from the group consisting of Meloidogyne incognita, Heterodera glycines , and Rotylenchulus reniformis.

2. The method for controlling a plant parasitic nematode according to claim 1 , wherein the target is at least one selected from the group consisting of Tylenchoidea plant parasitic nematodes, plants, soil, and culture carriers other than the soil.

3. The method for controlling a plant parasitic nematode according to claim 2 , wherein the target is soil or a culture carrier other than the soil, and the effective amount is 0.1 g to 1000 g per 10 are of the soil.

4. The method for controlling a plant parasitic nematode according to claim 2 , wherein the target is a plant seed, and the effective amount is 0.01 g to 100 g per 1 kg of the plant seed.

5. The method for controlling a plant parasitic nematode according to claim 1 , further comprising: treating at least one target selected from the group consisting of dicotyledons, soil, and culture carriers other than the soil with the effective amount of the compound, wherein the method is also a method for promoting growth of the dicotyledons.

6. A method for controlling a Tylenchoidea plant parasitic nematode, comprising:

treating a target with a control agent comprising at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), enantiomers thereof, and agriculturally and horticulturally acceptable acid addition salts thereof as an active ingredient with an effective amount of the active ingredient

wherein the Tylenchoidea plant parasitic nematode is at least one plant parasitic nematode selected from the group consisting of Meloidogyne incognita, Heterodera glycines , and Rotylenchulus reniformis.

7. The method for controlling a plant parasitic nematode according to claim 6 , wherein the control agent further comprising a powdery carrier, and being a dust or a powder formulation.

8. The method for controlling a plant parasitic nematode according to claim 6 , wherein the control agent further comprising a granular or powdery carrier and a surfactant, and being a granule or a dust-granule mixture.

9. The method for controlling a plant parasitic nematode according to claim 6 , wherein the control agent further comprising a liquid carrier, a surfactant, and a thickener, and being a flowable formulation.

10. The method for controlling a plant parasitic nematode according to claim 6 , wherein the control agent further comprising a powdery carrier and a surfactant, and being a wettable powder.

11. The method for controlling a plant parasitic nematode according to claim 6 , wherein the target is at least one selected from the group consisting of Tylenchoidea plant parasitic nematodes, plants, soil, and culture carriers other than the soil.

12. The method for controlling a plant parasitic nematode according to claim 6 , wherein the target is soil or a culture carrier other than the soil, and the effective amount is 0.1 g to 1000 g per 10 are of the soil.

13. The method for controlling a plant parasitic nematode according to claim 6 , wherein the target is a plant seed, and the effective amount is 0.01 g to 100 g per 1 kg of the plant seed.

14. The method for controlling a plant parasitic nematode according to claim 6 , further comprising: treating at least one target selected from the group consisting of dicotyledons, soil, and culture carriers other than the soil with the effective amount of the compound, wherein the method is also a method for promoting growth of the dicotyledons.
