Hybrids between existing taxa also have the potential to be invasive although I can't think of an example right now. Perhaps the USDA should prohibit hybridizing as well. A way around this is to label the plant imports as toxic chemicals. Seems to be no barrier to that. Here in California, they purposely put toxic waste (fluorosalicylic acid) into our water supply. It's the law!
