Brugmansia Virus and Diseases Brugmansia Virus and Diseases
| Many Brugmansia never show major symptoms of the many viruses they are susceptible to, and they live long and happy lives. Insects, dirty hands and tools, exposure to tobacco products, exposure to other genera that are host to viruses, and mechanical wounds (such as taking cuttings for propagation purposes), are the most common reasons for Brugmansia plants becoming infected with viruses. Neglect, lack of water, lack of nutrition, excessive heat, cold weather and freezes, all contribute to and create stressful conditions for Brugmansia. During these stressful times the virus symptoms are most evident. When properly cared for the plant's virus symptoms often disappear and the plant resumes normal and healthy looking growth. ... but the plant is still infected! |

Heirloom Tomatoes, and unfortunately Datura, are not good choices as companion plants for your Brugmansia. 7-Keep propagation tools sterile. Boil tools in water 5 minutes, wash with strong soap. Dipping tools in household bleach is not effective for virus decontamination 8-Do not reuse the soil from an obviously sick plant. The roots from infected plants are also infected. You can not remove every tiny root from the soil. Source of information UMN 9-Protect your plants from excessive heat (especially B. sanguinea, B. flava, B. vulcanicola), and from cold temperatures.

Tobacco mosaic stunts the plants growth, causes blotches of mixed greens and yellows combined with normal leaf color, deforms fruit (seedpods) and flowers. Tobacco mosaic greatly reduces the looks of the plant but rarely kills it. As with all plant viruses, once the plant is infected with Tobacco mosaic, it is infected for life. Tobacco mosaic is one of the most common plant viruses found throughout the world.
