Abstract

A pesticidal composition comprises a synergistically effective amount of a nicotinic acetylcholine receptor (nAChR) allosteric activator 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-(pyridine-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) allosteric activator 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.

2. The composition of claim 1, wherein the nAChR allosteric activator compound comprises a spinosyns-based compound.

3. The composition of claim 1, wherein the nAChR allosteric activator compound comprises at least one of spinetoram and spinosad.

4. The composition of claim 1, wherein the nAChR allosteric activator compound comprises spinetoram.

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

6. 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.

7. 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.

8. 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.

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 allosteric activator compound is no more than about 10256:

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 allosteric activator compound is no more than about 32:

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 allosteric activator compound is no more than about 8:

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 allosteric activator compound is no more than about 0.40:

1.

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

Y;

wherein,

X is the parts by weight of the pesticide (I), (II), or any agriculturally acceptable salt thereof, and the numerical range is 0<

X≦

20;

Y is the parts by weight of the nAChR allosteric activator compound, and the numerical range is 0<

Y≦

20.

14. The composition of claim 13, wherein the ranges of weight ratios of the pesticide (I), (II), or any agriculturally acceptable salt thereof and the nAChR allosteric activator compound are X₁:

Y₁ to X₂;

Y₂,

wherein one of the following conditions is satisfied;

(a) X₁>

Y₁ and X₂<

Y₂;

or

(b) X₁>

Y₁ and X₂>

Y₂;

or

(c) X₁<

Y₁ and X₂<

Y₂.

15. 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.

16. The method of claim 15, wherein the nAChR allosteric activator compound comprises a spinosyn-based compound.

17. The method of claim 15, wherein the nAChR allosteric activator compound comprises at least one of spinetoram and spinosad.

18. The method of claim 15, wherein the nAChR allosteric activator compound comprises spinetoram.

19. The method of claim 15, wherein the pests comprise sap feeding insects, chewing insects, or both.

20. The method of claim 15, wherein the pests comprise at least one of diamondback moth, Plutella xylostella;

cotton aphid, Aphis gossypii;

South American brown stink bug, Euschistus heros;

Western plant bug, and Lygus Hesperus.

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

22. The method of claim 21, wherein the nAChR allosteric activator compound comprises a spinosyns-based compound.

23. The method of claim 21, wherein the nAChR allosteric activator compound comprises at least one of spinetoram and spinosad.

24. The method of claim 21, wherein the nAChR allosteric activator compound comprises spinetoram.
