- bigbillheck 3y agoIt's a host for white pine blister rust.
- chucksta 3y agoman that's complicated
- bigbillheck 3y 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 3y 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 3y agoDoes it go from white pine back to currants?
- SeanLuke 3y agoYes.
- pfdietz 3y agoGreat. I was hoping we could see alternating currants.
- Terr_ 3y ago> alternating currants Except we know the hertz will harm local timbre, even if some are okay the the currant's whine.
- bigbillheck 3y ago@dang get over here and do something about this.

- QuercusMax 3y agoIn Europe they decided to get rid of the white pines (which are not native) in favor of the blackcurrants.
- euroderf 3y agoInteresting! Citation?
- QuercusMax 3y 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
- davexunit 3y agoBlackcurrant bans feel too heavy-handed to me. Currants are a wonderful berry, very easy to grow, and one of the easiest woody plants to propagate.
- quickthrowman 3y agoThere are plenty of other native berries in North America. White pines are rather majestic trees, particularly the old growth ones. [0] I’m happy with white pines and raspberries/blueberries, Europe can keep their blackcurrants.
