Abstract

Disclosed herein are pest controlling compositions (i.e., biopesticides) comprising one or more entomopathogenic fungi which. Further disclosed are methods of using such compositions for controlling invasive pests, particularly agriculturally relevant pests.

First claim

1 . A biopesticide comprising an agriculturally suitable carrier, a pesticidally effective amount of at least one fungal pesticide, at least one sorbitan fatty acid surfactant, and at least one sorbitol ethoxylate ester surfactant.

2 . The biopesticide of claim 1 , where the at least one sorbitan fatty acid surfactant includes a sorbitan monostearate or a sorbitan monooleate, and the at least one sorbitol ethoxylate ester surfactant includes a polyoxyethylene sorbitol hexaoleate.

3 . The biopesticide of claim 2 , where the sorbitan monostearate includes Span™ 60 and the sorbitan monooleate includes Span™ 80.

4 . The biopesticide of claim 2 , where the polyoxyethylene sorbitol hexaoleate includes a polyoxyethylene (40) sorbitol hexaoleate.

5 . The biopesticide of claim 2 , where the polyoxyethylene sorbitol hexaoleate includes Cirrasol® G-1086.

6 . The biopesticide of claim 1 , where a total amount of surfactant is between about 1 to about 50 wt. %, about 2 to about 30 wt. %, about 24 to about 36 wt. %, about 27 to about 33 wt. %, or about 29 to about 31 wt. % of the biopesticide.

7 . The biopesticide of claim 1 , where a total amount of sorbitan fatty acid surfactant is between about 0.5 to about 7.5 wt. %, and a total amount of sorbitol ethoxylate ester surfactant is between about 7.5 to about 30 wt. % of the biopesticide.

8 . The biopesticide of claim 1 , where a ratio of the sorbitan fatty acid surfactant to the ethoxylate ester surfactant is between about 0.02 to 1 to about 0.25 to 1.

10 . The biopesticide of claim 1 , where a total amount of surfactant is about 30 wt. % of the biopesticide, the sorbitan fatty acid surfactant includes a sorbitan monooleate, the sorbitol ethoxylate ester surfactant includes a polyoxyethylene (40) sorbitol hexaoleate, and a ratio between the sorbitan monooleate and the polyoxyethylene (40) sorbitol hexaoleate is about 0.08 to 1.

11 . The biopesticide of claim 1 , where the biopesticide includes an anti-settling agent.

12 . The biopesticide of claim 11 , where the anti-settling agent includes fumed silica.

13 . The biopesticide of claim 1 , where the agriculturally acceptable carrier includes a paraffinic oil.

14 . The biopesticide of claim 1 that, when diluted with water at a rate of between about 5.00 g of biopesticide to 95.00 g of water, to about 0.01 g of biopesticide to 99.99 g of water, is well dispersed, does not clog a delivery apparatus when the biopesticide is used to contact a plant, and causes minimal phytotoxic injury to the plant.

15 . The biopesticide of claim 1 , where the at least one fungal pesticide includes Alternaria cassiae, Fusarium lateritum, Fusarium solani, Verticillium lecanii, Aspergillus parasiticus, Metarhizium anisopliae , or Beauveria bassiana.

16 . The biopesticide of claim 1 , where the at least one fungal pesticide includes a strain of Metarhizium anisopliae having a deposit accession number DSM 3884, a deposit accession number DSM 3885, or combinations thereof.

17 . A biopesticide comprising an agriculturally suitable carrier, a pesticidally effective amount of a strain of Metarhizium anisopliae , a sorbitan fatty acid surfactant, and a sorbitol ethoxylate ester surfactant;
the biopesticide capable of being diluted in water to about 0.8 g of biopesticide to 99.2 g of water to provide a diluted biopesticide; the diluted biopesticide able to be delivered without the Metarhizium anisopliae adhering/sticking to an inner wall of a delivery device and without a phytotoxic effect on a plant when the diluted biopesticide is applied to the plant.

18 . A method of controlling a plant pest, comprising:
contacting the plant pest with a biopesticide that includes an agriculturally suitable carrier, a pesticidally effective amount of at least one fungal pesticide, a sorbitan fatty acid surfactant, and a sorbitol ethoxylate ester surfactant.

19 . The method of claim 18 , where the sorbitan fatty acid surfactant includes a sorbitan monostearate or a sorbitan monooleate, and the sorbitol ethoxylate ester surfactant includes a polyoxyethylene sorbitol hexaoleate.

20 . The method of claim 19 , where the sorbitan monostearate includes Span™ 60, the sorbitan monooleate includes Span™ 80, and the polyoxyethylene sorbitol hexaoleate includes Cirrasol® G-1086.

21 . The method of claim 18 , including, prior to the contacting step:
diluting the biopesticide with water at a rate no more dilute than 0.8 g biopesticide to 99.2 g of water.

22 . The method of claim 21 , where contacting the plant pest with the diluted biopesticide does not clog a delivery apparatus and causes minimal phyotoxic injury to a plant.
