Only Eastern 1 & 2 locations will have tobacco plants remaining for the coming week. With the exception of flea beetles, very little has been detected during scouting at this point.

Here is the scouting report from the control plots for our experiment at the Upper Coastal Plain Research Station near Rocky Mount, NC. Our plots at the Lower Coastal Plain Research Station near Kinston, NC had their final priming this week so we are done scouting there. For some of these experiments, the control plots receive no insecticide treatments for the entire season. For some of the experiments, we are interested in only caterpillar pests so all plants in the experiment, including the control plots, are treated in the greenhouse with imidacloprid to prevent other early season pests.
