Collapse ▲As part of our annual flue-cured tobacco production surveys, we ask county extension agents questions about current insect pest-control practices in flue-cured tobacco. As this information might be of use to other county agents and various stakeholders in tobacco production, we are sharing the survey results on the tobacco portal.
Survey Response
Response to the survey covered 85,248 acres of flue-cured tobacco production in 17 counties across NC.
Table 1. Acres responding to survey by county
To see how this response compares to previous years, see our 2015 post on survey methods and response.
Greenhouse Pest Control
The past three years, acephate (Orthene) was the most common non-neonicotinoid applied to treat pests in greenhouses with an estimated 50% of 80,695 reporting acres treating with it in 2014, an estimated 26% of 105,292 reporting acres treating with it in 2015, and an estimated 24% of 75,405 reporting acres treating with it in 2016.
Soil-Applied Insecticides
In 2014 and 2015, around 70% of reporting acreage was transplanted with plants treated with soil-applied neonicotinoids in the greenhouse. In 2016, that number decreased to around 50% of reporting acres. For more information about using soil-applied insecticides, see the North Carolina Agricultural Chemicals Manual.
Table 1: Percentages of transplants treated with neonicotinoids in the greenhouse.

|---|---|---|---|---|---|---|
| Admire and generic imidacloprid | 85,069 | 64,692 | 64,484 | 69.7 % | 65.0 % | 42.8 % |
| Platinum (thiamethoxam) | 55,789 | 56,461 | 49,071 | 6.0 % | 9.6 % | 7.2 % |
Foliar Pests and Insecticide Applications
Caterpillars were the pests most consistently treated with foliar insecticides. Pre-topping, around 70% of reporting acres were treated for tobacco budworms (Heliothis virescens), and post-topping around 50% of reporting acres were treated for tomato and tobacco hornworms (Manduca spp.) For more information on pest insects, see our insect IPM page.
