Crop rotation
The cultural control, Crop rotation, is very effective at limiting disease. The longer an infected field is planted in a crop other than the initial infected crop, the lower the population will become. A minimum three-year rotation is recommended. Crop rotation is recommended in combination with resistant varieties as genetic controls. Burley Tobacco, Burley Tobacco hybrids, and Dark Tobacco are varieties of tobacco that are resistant to Black Shank. Resistance however is not reliable because a single variety has resistance to only a few races of Black Shank. Finding new lines of resistance is becoming increasingly important due to new discovered resistant races of the pathogen.
