Our weekly scouting, now in week five, has shown a slight increase in flea beetle activity, but still well below the threshold amounts required to begin treatment. After reports of budworms in some grower locations, no budworms were observed at our sites.  We, along with many others, also observes thrips at all of our sites.

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.
