Since 1971, Oregon has used a flea beetle against tansy ragwort; 7 years later, the state said the biocontrol had cut infestations by 90%

In Oregon, a tiny flea beetle has emerged victorious in the battle against toxic tansy ragwort, a notorious invasive weed that has plagued farmers and livestock alike. This innovative biological control, where beetle larvae target the weed's root crown, effectively stunted its regrowth. Independent studies have validated the beetle's success, showcasing a sustainable and eco-friendly alternative to traditional chemical herbicides to combat agricultural threats.
