Abstract

Described and claimed are methods and compositions for the control of pests. According to the subject invention, a fatty acid or mixture of fatty acids can be combined with one or more avermectins or related compounds to achieve synergistic control of pests.

Claims

1. A composition for the control of a pest, said composition comprising a first ingredient which is a monocarboxylic acid having about seven to about twenty carbon atoms, or a salt thereof, or a mixture of said monocarboxylic acids or salts thereof, and a second ingredient which is an avermectin, ivermectin, or milbemycin wherein said first ingredient is present at a concentration of at least about 0.2%, and said second ingredient is present in a concentration between about 0.25 to about 3 ppm.

2. The composition, according to claim 1, wherein said first ingredient can be represented by the following formula:

space="preserve" listing-type="equation">R.sub.1 Y.sub.1 Y.sub.2 COOR.sub.2

wherein

R₁ =C6 to C19 saturated or unsaturated hydrocarbon, or an epoxide, or cyclopropane thereof

Y₁ =H, C1-C5 hydrocarbon, or hydroxyl at any position along R₁

Y₂ =H, C1-C5 hydrocarbon, or hydroxyl at any position along R₁

R₂ =H, or salt.

3. The composition, according to claim 1, wherein said first ingredient has from about fifteen to about twenty carbons.

4. The composition, according to claim 1, wherein said first ingredient is a mixture of monocarboxylic acids or salts thereof.

5. The composition, according to claim 1, wherein said first ingredient is saturated and unsubstituted.

6. The composition, according to claim 1, wherein said first oleic acid or a salt thereof.

7. The composition, according to claim 1, wherein said second ingredient is an avermectin.

8. The composition, according to claim 1, wherein said second ingredient is a milbemycin.

9. The composition, according to claim 1, wherein said second ingredient is ivermectin.

10. The composition, according to claim 1, wherein said composition is formulated to be a drench product to be applied to livestock or pets.

11. The composition, according to claim 10, wherein said first ingredient has from about seven to about eighteen carbons.

12. The composition, according to claim 11, wherein said first ingredient is decanoic or nonanoic acid or salts thereof.

13. The composition, according to claim 1, wherein said first ingredient is a metal salt of a monocarboxylic acid.

14. A method for the control of a pest, said method comprising the administration to said pest of an effective amount of a composition comprising a first ingredient which is a monocarboxylic acid having about seven to about twenty carbons, or a salt thereof, or a mixture of monocarboxylic acids or salts thereof, and a second ingredient which is an avermectin, ivermectin, or milbemycin, wherein said first ingredient is applied at a rate of at least about 1 lb/acre and said second ingredient is applied at a concentration between about 0.25 and about 3 ppm.

15. The method, according to claim 14, wherein said first ingredient can be represented by the following formula:

space="preserve" listing-type="equation">R.sub.1 Y.sub.1 Y.sub.2 COOR.sub.2

wherein

R₁ =C6 to C19 saturated or unsaturated hydrocarbon, or an epoxide, or cyclopropane thereof

Y₁ =H, C1-C5 hydrocarbon, or hydroxyl at any position along R₁

Y₂ =H, C1-C5 hydrocarbon, or hydroxyl at any position along R₁

R₂ =H, or salt.

16. The method, according to claim 14, wherein said first ingredient has from about fifteen to about twenty carbons.

17. The method, according to claim 14, wherein said first ingredient oleic acid or a salt thereof.

18. The method, according to claim 14, wherein said second ingredient is an avermectin.

19. The method, according to claim 14, wherein said second ingredient is a milbemycin.

20. The method, according to claim 14, wherein said second ingredient is ivermectin.

21. The method, according to claim 14, wherein said composition is formulated to be a drench product to be applied to livestock or pets.

22. The method, according to claim 14, wherein said first ingredient has from about seven to about eighteen carbons.

23. The method, according to claim 14, wherein said first ingredient is a metal salt of a monocarboxylic acid.

24. The method, according to claim 14, wherein said pest is in a taxonomic family selected from the group consisting of Tetranychidae, Eriophyidae, Tenuipalpidae, Tarsenomidae, Aleyrodidae, Psyllidae, Agromyzidae, Cicadellidae, Membracidae, Coccidae, Pseudococcidae, and Diaspididae.

25. The method, according to claim 14, wherein said pest is selected from the group consisting of Thysanoptera, Hymenoptera, Hemiptera, Cicadellidae, Membracidae, Coccidae, Pseudococcidae, Diaspididae, and Solenopsis.

26. The method, according to claim 14, wherein said pest is selected from the group consisting of mites and whiteflies.

27. The method, according to claim 21, wherein said pest is selected from the group consisting of fleas, ticks, mites, lice, and flies.

28. A method for the control of a pest, said method comprising the sequential application to said pest of a first composition comprising a monocarboxylic acid having about seven to about twenty carbon atoms, or a salt thereof, or a mixture of monocarboxylic acids or salts thereof, and a second composition comprising avermectin, ivermectin, milbemycin, or a derivative of avermectin, ivermectin, or milbemycin.

29. The method, according to claim 28, wherein said monocarboxylic acid can be represented by the following formula:

space="preserve" listing-type="equation">R.sub.1 Y.sub.1 Y.sub.2 COOR.sub.2

wherein

R₁ =C6 to C19 saturated or unsaturated hydrocarbon, or an epoxide, or cyclopropane thereof

Y₁ =H, C1-C5 hydrocarbon, or hydroxyl at any position along R₁
