| Abstract: | The transfer of bifenthrin/carrier combinations from glass, wax, and cotton leaves to tobacco budworm, Heliothis virescens, larvae was determined. Persistence of bifenthrin/oil combinations on the cotton leaf was also determined. Results indicated that the amount of bifenthrin/carrier transferred from glass to sixth-instar tobacco budworm was influenced by viscosity; however, transfer from wax to larvae was not affected. In spray table tests, amounts of bifenthrin bound to leaf surfaces over time were influenced by carrier viscosity. Oils transferred significantly greater (up to 50%) amounts of bifenthrin from cotton leaves to tobacco budworm than water. The transfer of bifenthrin using vegetable and hydrocarbon based oils from cotton leaves to larvae was affected by carrier viscosity; however, there was no relationship between transfer and viscosity when silicone fluid was included in the comparison. Silicone fluid was twice as viscous as soybean oil, yet bifenthrin transfer to tobacco budworm was greatest when mixed in soybean oil. Larval mortality in the bioassay substantiated the amount of bifenthrin detected on larvae in the transfer test |
