Context: Two Chinese researchers have been charged in the US for smuggling Fusarium graminearum, a toxic crop-destroying fungus, raising fears of agro-terrorism.
About Fusarium graminearum:
• What is It? Fusarium graminearum is a fungal pathogen that causes Fusarium Head Blight (FHB), primarily in wheat, maize, barley, and other cereals.

• Vector Type: It is a fungus and spreads via airborne spores, contaminated seeds, and moist soil.
• Banned/Regulated Under: While not universally banned, import and research involving F. graminearum are highly regulated under biosecurity laws in the US and many countries. Requires biosafety clearance from agriculture and customs departments.

About Agro-Terrorism:
• Definition: Agro-terrorism refers to the deliberate use of biological agents (fungi, bacteria, pests, or toxins) to attack a nation’s agriculture sector, aiming to cause economic disruption, food insecurity, and public fear.
