Tobacco budworm activity beginning
I received my first tobacco budworm calls for 2013 today, so it’s safe to say that budworm moths are active in eastern North Carolina. The threshold for tobacco budworm management is 10% infested plants (this means live larvae in 10% of sampled plants, not 10% of plants with feeding injury). This threshold is very conservative, so treatment at lower than 10% are not justified.
