Claim: Weed biocontrol, an application of a plant virus which are grouped into 73 genera, uses viruses to trigger lethal systemic necrosis while genome editing enhances toxin and pesticide delivery.
Evidence: Viruses triggering lethal systemic necrosis as bioherbicides Weed biocontrol Enhanced toxin and pesticide delivery for insect and nematode control Pest biocontrol Plant viruses are grouped into 73 genera and 49 families.
