We are at week nineteen of scouting, and harvesting is happening at all locations. The Piedmont site continued with harvesting this week and the Eastern 3 & 4 locations have completed harvesting this week. Since harvesting is completed for those sites, they have been removed from the scouting report. None of our grower plots have hornworms or flea beetles above threshold. We did see a few budworms present on suckers, but they were not above threshold.

Here are the scouting reports from the control plots for our experiments at the Upper Coastal Plain Research Station near Rocky Mount, NC and the Lower Coastal Plain Research Station near Kinston, NC. 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.
