Leaf spot? On bells of ireland flower farm

Asked June 19, 2019, 5:01 PM EDT

I have a small flower farm in Aurora. My bells of Ireland look have faded spots on their leaves. It hasnt moved to the bells yet. Is this something that you can test at one of your facilities? Thanks. Mindy Todd Petals

Hi Mindy,

Thanks for your question.

Here is information on sending plant material to the OSU plant clinic in Corvallis.

Please download and fill out the plant disease form to include when submitting your sample: https://bpp.oregonstate.edu/sites/agscid7/files/bpp/attachments/plant-disease-form-2019.pdf

COLLECTING
1. Select material showing the symptoms you are concerned about. Send several samples showing various stages of disease, especially early symptoms. If possible, send a healthy sample as well.

2. Include all parts of the plants, including roots where practical. Enclose roots and soil in a plastic bag. Enclose the rest of the plant in a separate plastic bag.

3. If it is not practical to send the entire plant, include several affected portions of the plant. With stem or branch disorders, be sure the sample includes live material as well as the diseased portion, e.g. include the margin between healthy and diseased tissue.

PACKING
1. Keep plants cool and moist before shipping. Bag roots separately to keep soil from the rest of the plant, then enclose the entire plant in plastic to keep from drying out. Mail as soon as possible after collecting. Mail specimens early in the week to avoid delay in the post office over weekends or holidays.
2. Pack in a sturdy container to prevent crushing in transit. Use paper to pack the specimen firmly in the container.
3. Identify the package with labels both outside and inside.
4. Put the label and Plant Disease Form in a waterproof barrier, such as plastic.
