6 . The method of claim 1 , wherein the at least one seed is produced from a plant in genus Brassica.
7 . The method of claim 6 , wherein the at least one seed comprises at least one of B. napus, B. juncea, B. carinata, B. rapa, B. oleracea, B. rupestris, B. septiceps, B. nigra, B. narinosa, B. perviridus, B. tournefortii , and B. fructiculosa.
8 . The method of claim 1 , wherein contacting at least one seed with at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine comprises applying the at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine to the at least one seed before sowing the at least one seed.
9 . The method of claim 1 , wherein contacting at least one seed with at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine comprises at least one of spraying, coating, dusting, and soaking the at least one seed with the at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine.
10 . The method of claim 1 , wherein contacting at least one seed with at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine comprises applying multiple applications of the at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine to the at least one seed.
11 . The method of claim 1 , wherein contacting at least one seed with at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine comprises contacting the at least one seed with a formulation comprising the at least one N-substituted(6-haloalkylpyridin-3-yl)alkyl sulfoximine and at least one inert carrier.
12 . The method of claim 11 , wherein the formulation further comprises at least one adjuvant material.
13 . The method of claim 11 , wherein the formulation further comprises at least one additional pesticide material.
14 . A method of controlling insects, comprising:
applying sulfoxaflor to at least one seed to control at least one flea beetle species.
15 . The method of claim 14 , wherein applying sulfoxaflor to at least one seed comprises applying sulfoxaflor to the at least one seed concurrently with at least one additional material.
16 . The method of claim 14 , wherein applying sulfoxaflor to at least one seed comprises applying sulfoxaflor to the at least one seed consecutively with at least one additional material.
17 . The method of claim 14 , wherein the at least one seed comprises at least one canola seed.
