Abstract

A pesticidal composition comprises a synergistically effective amount of a nicotinic acetylcholine receptor (nAChR) agonist compound and a pesticide selected from N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-((3,3,3-trifluoropropyl)thio)propanamide (I), N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-((3,3,3-trifluoropropyl)sulfinyl)propanamide (II), or any agriculturally acceptable salt thereof. A method of controlling pests comprises applying the pesticidal composition near a population of pests. A method of protecting a plant from infestation and attack by insects comprises contacting the plant with the synergistic pesticidal composition.

Claims

1. A pesticidal composition comprising a synergistically effective amount of:

a nicotinic acetylcholine receptor (nAChR) agonist compound selected from acetamiprid or dinotefuran; and

a pesticide selected from the group consisting of N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-((3,3,3-trifluoropropyl)thio)propanamide (I), N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-((3,3,3-trifluoropropyl)sulfinyl)propanamide (II), and any agriculturally acceptable salt thereof;

2. The composition of claim 1, wherein the nAChR agonist compound is acetamiprid.

3. The composition of claim 1, wherein the nAChR agonist compound is dinotefuran.

4. The composition of claim 1, further comprising a phytologically-acceptable inert carrier.

5. The composition of claim 1, further comprising an additive selected from a surfactant, a stabilizer, an emetic agent, a disintegrating agent, an antifoaming agent, a wetting agent, a dispersing agent, a binding agent, dye, filler, or combinations thereof.

6. The composition of claim 1, further comprising one or more compounds having acaricidal, algicidal, avicidal, bactericidal, fungicidal, herbicidal, insecticidal, molluscicidal, nematicidal, rodenticidal, virucidal or combinations thereof properties.

7. The composition of claim 1, further comprising one or more compounds that are antifeedants, bird repellents, chemosterilants, herbicide safeners, insect attractants, insect repellents, mammal repellents, mating disrupters, plant activators, plant growth regulators, synergists, or combinations thereof.

8. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is from about 2:

1 to about 2000;

1.

9. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is no more than 513:

1.

10. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is no more than 256:

1.

11. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is no more than 128:

1.

12. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is no more than 32:

1.

13. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is no more than 20:

1.

15. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is from about 8:

1 to about 513;

1.

16. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is from about 4:

1 to about 513;

1.

17. The composition of claim 1, wherein a weight ratio of the pesticide selected from (I), (II) or any agriculturally acceptable salt thereof to the nAChR agonist compound is from about 2:

1 to about 513;

1.

18. The composition of claim 1, wherein the weight ratio of the pesticide (I), (II), or any agriculturally acceptable salt thereof and the nAChR agonist compound is X:

19. A method of controlling pests comprising applying the pesticidal composition of claim 1, near a population of pests, in an amount sufficient to control the pests.

20. The method of claim 19, wherein the pests are sucking insects, chewing insects, or a combination thereof.

21. The method of claim 19, wherein the pests includes brown stink bug, Euschistus heros.

22. The method of claim 19, wherein the pests includes Western flower thrips, Frankliniella occidentalis (Pergande).

23. A method of protecting a plant from infestation and attack by pests, the method comprising contacting the plant with the pesticidal composition of claim 1.
