Gardeners are requested to help in this research by sending in samples of leaf material from:
1. Ornamental species of Solanum, for example S. crispum and S. laxum (previously known as S. jasminoides), whether or not they look like they are virus-infected. This is because some viruses that affect these plants can be symptomless in ornamentals.
2. Tomato, potato and aubergine, if they have virus symptoms (see picture below).
Please include the name of the plant the sample was taken from (Latin name, common name and / or cultivar), the postcode of where the plant is growing as well as date of planting and place of purchase if known. Please also provide your name and email or postal address.
Several whole leaves should be taken from your chosen plant. Put the fresh leaves in a slightly inflated sealed bag and post this to:
Plant Health - Science,
RHS Garden Wisley,
Please include the postcode of where the plant is growing as well as date of planting and place of purchase if known. If you would like to receive results from the experiment please provide your name and email or postal address.
We will let you know if your plant tests positive for viruses and will post a report online so gardeners can see the overall results.
