Mark D. Ricker

It is with sadness that I just recently learned of Mark's passing. We were colleagues at Nunhems and shared a great working relationship and friendship. I will remember the full life he lived, his endless thoughtfulness, and his eternal spirit. If someone from the family could please contact me, I would like to share the memorial trees certificate. Heartfelt condolences.

It is really sadness to know the news. He showed me that he has clear goal and strong encourage in his life and will. He chase medical scientist after he worked 30years in his favorite career , it is important he got officially licensed as Medical Laboratory Scientist.

I am saddened. I worked with Mark for 16 years. I know he would laugh when I say his note taking was something between shorthand and hieroglyphics. When having a discussion with him you would know the conversation was over when he said “Thank you” and he would walk away. When he went to work for Nunhems in 2000 he moved to Amador County where I lived at the time. On one visit to his lot where he was going to build a house, he showed me a tree house that he built for his children. It was...

In loving memory of a wonderful person. From the phytopathology team coworking together globally, we had the chance and the fortune to meet and know you. Ciao, Daniele

Mark,
It's with great sadness that I take this news. You have been the mentor for tomato pathology, a great curious, precise reporter and true field plant pathologist. We've built a strong relationship and that is why I will always remember you as a building block for my career in Nunhems. I will always have in mind a picture of you observing and describing pathogens at the microscope what you enjoy the most at work.
Ciao Mark.

On behalf of all our company and colleagues I would like to say thank you for the work and dedication of Mark during his time at Nunhems. It is heartwarming to read the text that is of sadness but humor remembering the happy times.

Mark,

The shocking news came out of the dark. We lost contact after you switched your career from plants to people. I have always hoped that you would have been given the opportunity to utilize your expertise to help mankind for much, much longer. The world has lost a great scientist.

Farewell dr. Ricker, Mark, colleague, friend,

Dear Mark’s family and friends,
I’m deeply saddened to know that Mark is not there with us anymore.
I had known Mark since 2003, as my first teacher in the seed industry, as a colleague and as a wonderful friend, as we spent more and more time together discussing topics on plant pathology, nature, tourism and many other topics.
He was best plant doctor on vegetable crops and an expert in tomato pathology. I have learnt applied aspects of disease resistance screening from...
