Hi all,

Here's a link to an interesting article on a rust fungus that's threatening wheat crops:

There are many potential issues involved here: a possible climate change root cause, political issues involved in exchanging germplasm, traditional farming methods....

Any thoughts?

I suspect that "mono culture" issues may be involved also. In "nature" there is wide diversity. But to get maximum yield the supply corporations push a very narrow range of products. If it turns out they are susceptible to something... big trouble because ALL of them are the same.
