It has been a relative quiet spring for insect questions in tobacco, but last week I received several calls asking about aphid management in tobacco greenhouses. Aphids are an occasional pest in tobacco greenhouses, and the last time I had … Continue reading
One of the first projects my lab tackled when I began working in North Carolina was attempting to understanding the biology and behavior of tobacco splitworm. Our goal was to use this information to develop more effective scouting and management … Continue reading
This Wednesday, David Tarpy & Jen Keller of the NC State University Apiculture Program and I began an exploratory project to determine if honey bees will make honey from flowering tobacco, and if so, what the properties of that honey are. … Continue reading

I have received several calls from county agents in the last three weeks about stunted tobacco plants with a range of symptoms, each wondering about the possible role of systemic insecticides in the symptoms being observed. While there are more … Continue reading
While rating our experiments last week at the Lower Coastal Plain Research Station near Kinston, NC, we noticed a few tobacco or tomato hornworm eggs scattered among our plots. We weren’t the only ones–other tobacco research plots at the station … Continue reading
I just ran flight predictions for tobacco thrips (the primary vectors of tomato spotted wilt virus, TSWV, in NC tobacco), and they are predicted to begin within the next two weeks in eastern North Carolina. This means that growers in … Continue reading
I have been getting lots of questions about what our exceptionally warm spring weather means for tobacco pest management. I’ll have another post next week addressing the impact of warm winter weather and spring rain on thrips and tomato spot … Continue reading
I will be attending the annual field day at Cross Creek Seed near Raeford, NC tomorrow and discussing the results of a small scale drip applied insecticide trial in which we compared Coragen (chlorantraniliprole, DuPont) applied through drip irrigation 3 … Continue reading
