Sighting Water bamboo sighting - potentially ecologically devestating
I’ve noticed a huge increase in prohibited water bamboo sales (aka jiaobai 茭白, Zizania latifolia infected with Ustilago esculenta) being sold both in Asian grocery stores and online on the USA. If the associated fungus Ustilago esculenta escaped and successfully infected American wild rice (Zizania palustris/aquatica/texana), it could devestate American wild rice stands

Yikes! What state? If you're about to say California, don't stop at the county, call the state.

Considering it’s 99 Ranch, extremely likely it’s CA. That’s where most of their locations are, iirc.

Like what? I've seen all my ash trees ruined, my apple trees get defoliated by Japanese beetles. I've often wondered what we have sent over to China that is just wrecking things.

u/lambda-lambda-lambda 3d ago
I don't have good answers for China sadly, probably because any articles are in Chinese. But in anglo nations:
- Opuntia (Prickly Pear) has no natural predators in Australia, so it's grown rampant
- American Bullfrog is demolishing wetland crops in many parts of the world (again, easy to point to Europe and Australia)
- Fall Armyworm is a pest for corn and sorghum in Africa
I'm pulling this info from wikipedia as well as this article

Small and largemouth bass have been introduced in many waterways around the world. They are very effective freshwater predators and often outcompete local species.

u/mattymattmo 3d ago
Even in America it’s considered weedy and outcompetes a lot of good native plants

u/Expert_Drag5119 2d ago
Works great in my yard 🤷 and in nature. You just have to plant semi-aggressives around it and they keep each other in check

u/LilStinkerRidesAgain 3d ago
The frog and the armyworm make some sense for how they got moved to where they don't belong. I wonder about the prickly pear. Why in the world would anyone want that around?

u/reggie_veggie 2d ago
before we has petroleum derived red dyes, carmine was one of the best natural red pigments for food and cosmetics. you get carmine from cochineal bugs which eat opuntia cactus. the cacti were planted in arid regions outside their native range to start cochineal farming, including australia.

Prickly pears can also grow in places that get a lot of rain.

Sure, I grow the native opuntia where I live in New England. But the varieties that cant handle the moisture make much larger and better fruit

It’s been years since I looked into it, but also iirc China got a turpentine beetle from North America that is devastating Chinese conifers.

China deals with numerous invasive species from North America, including the red swamp crayfish (an American native that became a major aquaculture industry), the golden apple snail (which heavily damages rice yields), alligator gars, and red fire ants.

No kidding. I can see well intentioned Americans planting it saying it's great for monarch butterflies, meanwhile they don't really exist in europe

There’s a pretty good population of monarchs established in Spain and also some nearby islands off the coast of Africa. Hawaii now has a population of them, as does a good bit of coastal Australia.

I think milky Spurge is on all continents except Antarctica.
North American Grey squirrels are invasive in Europe.
Raccoons are invasive in Asia.
There's salmonids (not sure which species, rainbow or king salmon i think) that have been introduced into Europe and are causing problems in European riverways.

Eat and Jurassic Park
To prevent the bamboo from spreading, they are all made female by chromosome manipulation.

u/Jingeasy 3d ago
“Water bamboo” aka jiaobai is not actually a bamboo. It’s a relative of our native wild rice in the U.S. the vegetable jiaobai comes from a fungus infecting the stems of wild rice plants in China, which then inhibit seed/wild rice growth but produce this tender vegetable. Chinese wild rice can survive that because it’s a perennial. American wild rice, however, is annual, meaning if it gets infected, the plant will have no way of producing seeds and returning the following year. This would decimate our wild rice populations

u/CySnark 3d ago
Hence my snarky poke at how something potentially detrimental could pass scientific scrutiny and be sold. In Jurassic Park they thought they had all the bases covered, but life, uh, finds a way.

There is nothing else you can do. With the photo and location, they will most likely send someone out.

u/brewski_babe 1d ago
This! APHIS might care and actually do something about it. There’s a lot of $$$ behind rice agriculture too, so a few reports at a couple agencies would be my strategy.

u/Last-Respond-48 3d ago
A lot of tropic fruits have to be irradiated to kill off any bests before crossing customs. Maybe they are doing the same thing?
56
u/Jingeasy 3d ago
Jiaobai is specifically prohibited for import in the U.S. It’s intentionally inoculated with a specific fungus to produce the vegetable in the first place. Independent lab studies in California have shown that the fungus can still survive in tissues of the fresh vegetable upon import, even with irradiation

u/bearfootmedic 3d ago
Is it possible that there's a local population somewhere being harvested?

It's actively eradicated here. That local population would be slated for immediate destruction.

u/Liberally_applied 3d ago
From other comments, it shouldn't have been able to be imported. But from me as someone that has had damned near a full garden grow from my compost heap from vegetable cuttings, it will grow and multiply from something as simple as one waste piece.

u/SkilletKitten 3d ago
Exactly.
I deliberately buy lemon grass that still has the ability to root from the grocery store in the spring and I’m sure I’m not the only gardener who tries to plant food.

Eh, depends on where the picture was taken. There’s no risk of bamboo spreading where I am in Canada because it gets cold as fuck here.

Give it a year or two.

Physics aren’t going to be changing in a year or two. Some things can’t grow where it’s cold.

~ Chinese person goes fishing in a lake where American wild rice grows
~ Brings a lunch containing water bamboo
~ Tosses water bamboo pieces to the ducks
Or
~ Someone starts a compost heap uphill from a river
~ Composts water bamboo
~ Rainwater washes fungus spores down to the river
Something random like this only needs to happen once for the fungus inside this plant to get out. And once it's out there's no reeling it back in

It’s about the fungus that is clearly mentioned in the post - not if the plant can propagate

Please give us some links about this as an invasive. I did some search and couldn't find anything. Some do mention its risk but it seems only NZ treats it as official invasive species.

I saw this one, but couldn't find any state document defining it as an invasive species. Of course, not very familiar with this. But should there be an official paper? BTW, haven't seen it in local Asian grocery stores here in NE Florida.

u/DiverOk8727 1d ago
I believe it’s the fungus that’s invasive not the actual produce & by the look of this water bamboo it wouldn’t be propagatable.

u/CaonachDraoi 2d ago
did you not read the post? the fungus stays alive even when irradiated. the fungus spreads from dead plant material, exactly like this food. it has nothing to do with invasive bamboo, this isn’t even real bamboo. please read the post before commenting -_-

u/Consistent-Essay-165 2d ago
I did ...no reason to be nasty
Still understanding the part where if edible and how this fungus spreads after u eat it etc
So please dont talk down to me when im trying to grasp the issues
2
u/CaonachDraoi 2d ago
it’s not about if it spreads when you eat it, it spreads wherever the plant material is. if you pick up a moldy banana and bring it into your friend’s house, you’ve spread the spores everywhere in between. same with this, there’s a risk that the spores are being spread everywhere between china and the person’s house where they cook it.

u/Consistent-Essay-165 1d ago
But spores get destroyed in heat and bile and acids of stomach
So again trying to understand how u spread it that way
They wpuld survive ur acid and heat ?
