Dr. Sherm Thomson has asked my help in locating seeds of members of the
Brassicaceae. He is testing the use of two rusts as potential controls for
Isatis tinctoria (Dyers Woad) which is an undesirable, but highly
successful, invader in this part of the world. He and his colleagues need
to assess the effect of the rust on other members of the family, hence the
request. If you know of a botanic garden or germplasm repository that might
be able to assist Dr. Thomson, please would you forward this message.
Replies should be sent directly to Dr. Thomson (shermt at ext.usu.edu).
Thank you. Mary Barkworth
