Plant patents are considerably narrower in scope than utility patents, at least in the US. In particular you can't get plant patents that cover sexual reproduction of plants or asexual reproduction via edible tubers (like, say, potatoes do), so you can't use them to stop farmers replanting their seeds. That's why agritech companies wanted to be able to file utility patents on plants, which they eventually managed thanks to GMOs.

Also, the whole "plant patents date back to 1930" line is literally out of Monsanto's talking points.

Talking points tend to include facts. I'm sorry if the facts are not helping your narrative.

Yes, the 1930s plant patents are a bit different. But they are still corporations owning IP in plants. It didn't end the world then, it's nothing but a source of faux outrage now.
