It's the first time the lantana blister rust
has been used as a biocontrol anywhere in the world, which makes this release really exciting.
Fifteen years ago, she read studies showing that five to 20 percent of white pines exhibited resistance to blister rust
and thought there was a chance that similar resistance lurked in whitebark pine since the two pines are closely related.
Pathologists say some varieties of ribes are more resistant to white pine blister rust
than others, but varieties that were not showing any signs of the infection before are now found to be heavily infected.
And now a newer threat, expanding populations of mountain pine beetles, is exacerbating the effects of blister rust
Just like the white pine blister rust
, many conscientious objectors felt that they, too, were an invasive species in America, sent to the camps to be removed from the public eye lest they compromise the wartime spirit.

They give as examples modification of the life cycle of nematode parasites in musk oxen in the Arctic and warming in the western US allowing the mountain pine beetle to double its life cycle, become more abundant, and spread the fungus they carry to pine trees in the highest elevations of the Rocky Mountains, where pine blister rust
has become serious.
Currant growing in the US was banned in the 1960s when white pine blister rust
Gypsy moths, Dutch elm disease, and white pine blister rust
have taken a terrible toll.
The original black currant farming ban occurred when the United States began importing European white pine seedlings, and white pine blister rust
disease came with them.
Some whitebark pine trees are naturally resistant to the invasive disease white pine blister rust
Trees can be pretty nice, especially if they don't get overrun with caterpillars, Japanese beetles, canker rot or blister rust
Pruning treatments were tested for their effectiveness against white pine blister rust
At the same time, one in four whitebark pines in the Greater Yellowstone Ecosystem are fighting a much older epidemic: blister rust
, an Asian fungus that came over from Europe nearly a century ago.
Unfortunately, the bristlecone pine is being threatened by white pine blister rust
, which has devastated populations of white pines in the Northwest and is rapidly moving through the Rockies.
