Abstract
\r\n Two new systematic insecticides, Coragen 1.67 SC and Durivo SC applied as tray drenches in the greenhouse, as transplant water treatments in the field, and foliar treatments were compared to several foliar insecticides for tobacco budworm control in flue-cured tobacco. These trials were conducted with two tobacco growers on their farms located in Jeff Davis County, Georgia in 2010. Both Coragen 1.67 SC and Durivo SC were controlling tobacco budworms on both the Kenneth Williams and Jerry Wooten farms for forty-five days after the tray drench treatments and for forty days after the transplant water treatments. Even though Coragen 1.67 SC and Durivo SC transplant water and tray drench treatments were slower acting when compared to the foliar treatments, they provided tobacco budworm control equal to the foliar treatments on both farms. Using Coragen 1.67 SC or Durivo SC as a tray drench or transplant water treatments saved both tobacco growers from one to two insecticide sprays across the field.
