Abstract

Formulations are provided containing no VOC's or alternatively are low in VOC's for wide area space spray to control mosquitoes, flies, and other public health pests. When applied as an ultra-low volume (ULV) spray, these formulations have been observed to provide significantly superior control of pests.

Claims (28)

1. A method for controlling or preventing pest infestation, the method comprising spraying a water-based pesticidal formulation in an area susceptible to pest infestation, wherein the formulation comprises about 32% or greater acetyl tributyl citrate, wherein the formulation comprises 16% volatile organic compound (VOC) by weight or less, and wherein the formulation does not contain currently registered pesticides.

2. A method for controlling or preventing pest infestation, the method comprising spraying a water-based pesticidal formulation in an area susceptible to pest infestation, wherein the formulation comprises about 32% or greater acetyl tributyl citrate, wherein the formulation is VOC-exempt, and wherein the formulation does not contain currently registered pesticides.

3. The method of claim 1 , wherein the formulation is an ultra-low volume concentrate.

4. The method of claim 1 , wherein the pest is selected from the group consisting of: a mosquito, a fly, a cockroach, a bedbug, a sand fly, and a reduviidae.

5. The method of claim 1 , wherein the area susceptible to pest infestation is a complex canopy.

6. The method of claim 1 , wherein administration of the formulation provides a total average droplet density of ≥0.3 drops/mm2/fl oz of applied product.

7. The method of claim 1 , wherein administration of the formulation provides a variance in droplet density over a distance of 300 feet of 0.1 or less.

8. The method of claim 1 , wherein the formulation contains no VOC.

9. The method of claim 1 , wherein the formulation further comprises an essential oil.

10. The method of claim 1 , wherein the formulation comprises one or more of the following: an essential oil, an active ingredient eligible for minimum risk exemption regulations of the EPA (40 CFR 152.25(f)(1)), a humectant, an emulsifier, a surfactant, an antifoam agent, and/or a preservative.

11. The method of claim 1 , wherein the formulation further comprises at least one synergist selected from the group consisting of: bucarpolate, sesame oil synergists, dietholate, jiajizengxiaolin, octachlorodipropyl ether, piperonyl butoxide (PBO), piperonyl cyclonene, piprotal, propyl isome, sesame, sesamolin, sulfoxide, tribufos, and zengxiaoan.

12. The method of claim 1 , wherein the pest is an insect.

13. The method of claim 1 , wherein the pest is a mosquito.

14. The method of claim 1 , wherein the composition comprises a sesame oil synergist selected from sesamin and sesamolin.

15. The method of claim 1 , wherein the formulation comprises one or more pesticides eligible for minimum risk exemption regulations of the EPA (40 C.F.R. 152.25(f)(1)).

16. The method of claim 15 , wherein the one or more pesticides eligible for minimum risk regulations of the EPA (40 C.F.R. 152.25(f)(1)) is selected from the group consisting of: castor oil, cedarwood oil, cedarwood oil (China), cedarwood oil (Texas), cedarwood oil (Virginia), cinnamon, cinnamon oil, citric acid (2-hydroxypropane-1,2,3-tricarboxylic acid), citronella, citronella oil, cloves, clove oil, corn gluten meal, corn oil, cornmint, cornmint oil, cottonseed oil, dried blood, eugenol (4-allyl-2 methoxyphenol), garlic, garlic oil, geraniol (2E)-3,7-dimethylocta-2,6-dien-1-ol), geranium oil, lauryl sulfate lemongrass oil, linseed oil, malic acid (2-hydroxybutanedioic acid), peppermint, peppermint oil, 2-phenylethyl propionate, potassium sorbate (potassium (2E,4E)-hexa-2,4-dienoate), putrescent whole egg solids, rosemary, rosemary oil, sesame, sesame oil, sodium chloride, sodium lauryl sulfate (sulfuric acid monododecyl ester, sodium salt), soybean oil, spearmint, spearmint oil, thyme, thyme oil, white pepper, and zinc.

17. The method of claim 1 , wherein the formulation comprises one or more of castor oil, cedarwood oil, cedarwood oil (China), cedarwood oil (Texas), cedarwood oil (Virginia), cinnamon, cinnamon oil, citric acid (2-hydroxypropane-1,2,3-tricarboxylic acid), citronella, citronella oil, cloves, clove oil, corn gluten meal, corn oil, cornmint, cornmint oil, cottonseed oil, dried blood, eugenol (4-allyl-2 methoxyphenol), garlic, garlic oil, geraniol (2E)-3,7-dimethylocta-2,6-dien-1-ol), geranium oil, lauryl sulfate lemongrass oil, linseed oil, malic acid (2-hydroxybutanedioic acid), peppermint, peppermint oil, 2-phenylethyl propionate, potassium sorbate (potassium (2E,4E)-hexa-2,4-dienoate), putrescent whole egg solids, rosemary, rosemary oil, sesame, sesame oil, sodium chloride, sodium lauryl sulfate (sulfuric acid monododecyl ester, sodium salt), soybean oil, spearmint, spearmint oil, thyme, thyme oil, white pepper, and/or zinc.

18. The method of claim 17 , wherein the formulation comprises one of more of cinnamon oil, cloves, clove oil, sesame, sesame oil, soybean oil, thyme, and/or thyme oil.

19. The method of claim 1 , wherein the formulation is free of all pesticides except the acetyl tributyl citrate.

20. A method for controlling pest infestation, the method comprising spraying a water-based pesticidal formulation in an area susceptible to pest infestation, wherein the formulation comprises acetyl tributyl citrate, wherein the formulation comprises 16% volatile organic compound (VOC) by weight or less, wherein the formulation does not contain currently registered pesticides, wherein the method results in mortality of the pest within 24 hours wherein the formulation comprises about 32% or greater acetyl tributyl citrate.

21. The method of claim 20 , wherein the formulation contains no VOC.

22. The method of claim 20 , wherein the formulation comprises one or more of the following: an essential oil, an active ingredient eligible for minimum risk exemption regulations of the EPA (40 CFR 152.25(f)(1)), a humectant, an emulsifier, a surfactant, an antifoam agent, and/or a preservative.

23. The method of claim 20 , wherein the pest is an insect.

24. The method of claim 20 , wherein the pest is a mosquito.
