 Biotechnology is many different things but in a brief explanation it is the use of any organism or product to improve the product or organism and gain.

Fusarium head blight (FHB) is also commonly called Fusarium head scab, wheat scab, and head scab. In Ohio, this disease is caused primarily by the fungus.
