It's a host for white pine blister rust.
- chucksta 2y agoman that's complicated
- bigbillheck 2y agoSure is! https://www.apsnet.org/edcenter/disandpath/fungalbasidio/pdlessons/Pages/WhitePine.aspx https://www.apsnet.org/edcenter/disandpath/fungalbasidio/pdl... > The white pine blister rust pathogen is a typical heteroecious, macrocyclic rust that produces five distinct spore stages on two different hosts to complete its life cycle. The pycnial stage consists of pycniospores, or spermatia, which are haploid spores that fertilize compatible receptive hyphae. The two sexes are not distinguishable and are simply designated plus and minus. This is the stage where genetic recombination can occur that may lead to development of races of the rust. However, the nuclear cycle (i.e., dikaryogamy, diploidization, meiosis) of the blister rust fungus has not been fully determined, but is assumed to be the same as for other better known rust fungi such as Puccinia graminis. The aecial stage develops in host tissue occupied by pycnia the previous season (Figure 6). The fungus is perennial in the pine host and aeciospores are produced annually as long as the host tissues remain alive. Aeciospores are disseminated by wind over long distances, and Ribes spp. as far as 480 km (300 miles) from the nearest known white pines have been infected.
- kybishop 2y agoTo expand on this, many states have a large white pine lumber industry. The white pine is highly susceptible to a type of fungus harbored by currants. The fungus does not spread from white pine to white pine, only from currants to currant, or currant to white pine, so eliminating the nearby currants protects the white pine industry.
- pfdietz 2y agoDoes it go from white pine back to currants?
- SeanLuke 2y agoYes.
- pfdietz 2y agoGreat. I was hoping we could see alternating currants.
- gmfawcett 2y agobravissimo
- Terr_ 2y ago> alternating currants Except we know the hertz will harm local timbre, even if some are okay the the currant's whine.
- bigbillheck 2y ago@dang get over here and do something about this.
- QuercusMax 2y agoIn Europe they decided to get rid of the white pines (which are not native) in favor of the blackcurrants.
- euroderf 2y agoInteresting! Citation?
- QuercusMax 2y agoI believe I learned it in this video from "The History Guy": https://www.youtube.com/watch?v=LZAk1a0dqiM https://www.youtube.com/watch?v=LZAk1a0dqiM
- pvaldes 2y agoI was the French if I'm not wrong.
- pvaldes 2y ago"Je suis le Roi" moment (LOL) IT was the French
- tycho-newman 2y agoThe Ribena lobby is strong
- genewitch 2y agoI'd probably vote this way if given the choice, too.
- lo_zamoyski 2y agoApparently this is no longer much of an issue. Quoting [0]: "The federal ban was lifted in 1966, though many states maintained their own bans. Research showed that blackcurrants could be safely grown some distance from white pines and this, together with the development of rust-immune varieties and new fungicides, led to most states lifting their bans by 2003. Blackcurrants are now grown commercially in the Northeastern United States and the Pacific Northwest. Because of the long period of restrictions, blackcurrants are not popular in the United States, and one researcher has estimated that only 0.1% of Americans have eaten one. [...] By 2003 restrictions on Ribes cultivation had been lifted across most of the states, though some bans remain, particularly on the blackcurrant. State laws are enforced with varying degrees of efficiency and enthusiasm; in some states, officials effectively ignore the ban."

- genewitch 2y agothey're also available at a local walmart as rootstock. I bought one. If i find a nursery that has it i will buy more, but i like growing "weird" plants that no one has heard of, like soapberries, kumquats, that sort of thing.
- SEJeff 2y agoLookup beauty berries. Their fruit is edible and makes a nice jam. True to their name, they’re beautiful when fruiting.
- genewitch 2y agothose grow wild all over the land here, i just found out what they were called last year; although i had heard they're not edible but to leave them for birds. I'll ask the Ag Center if they're safe to eat.
- SEJeff 2y agoPlease do ask your AG center, but they’ll tell you they’re safe to eat. I make a jam of sorts with the berries. They’re not real sweet but are totally edible
