TMV
scouted May 22, 2026
- Scientific Name
- Tobacco mosaic virus
- Background
- Tobacco transplants are still in the greenhouse, awaiting rain to be transplanted; various fields on the farm are affected by TMV. A sample was submitted to the PDIC to determine if the transplants are free of the virus.
- Conclusion
- The issue was identified as Tobacco Mosaic Virus (TMV). Tobacco mosaic virus causes plants to have mosaic leaf patterns, distortion, and stunted growth. These symptoms often become more noticeable as plants mature, but may be mistaken for nutrient or environmental issues. TMV is very durable and can survive steaming, and there is no chemical control available for it. In the greenhouse, this means that infected plants and the trays that held them need to be disposed of.
