Tomato apical stunt viroid (TASVd)
Tomato apical stunt viroid
This viroid stunts the growth of tomato plants. If it came to New Zealand, it could harm our tomato growing industry and reduce your crop of tomatoes at home.
What does it look like?
An infected plant will:
- have curled and yellow leaves
- look stunted and unhealthy
- produce small, deformed, and pale tomatoes.
The symptoms look similar to many other tomato plant problems. You only need to be concerned if all symptoms are present in your tomato plants.
You're more likely to find infected plants in a glasshouse than in your garden.
