After eight years of exceptional leadership, renowned plant pathologist Steve Koike is retiring from TriCal Diagnostics.

Under Steve’s direction, TCD became a trusted name in plant pathology—known for accurate results, practical insights, and service that growers rely on.

We’re proud to share that Dr. Hanane Stanghellini, TCD co-founder, will continue this legacy of excellence. Same team. Same methods. Same commitment to the agricultural community.
