Yes but how can you stop the spread of pollen? That is the major problem.

Use the terminator gene concept, developed by monsato.. oh they we were forced to stop using that.

So, somehow a virus is going to select and transport the precise sequence of genetic material required from one species to another to give the new host immunity to to something we want it not to have immunity from, but leave behind all of the vast amount of dangerous genetic material that would render the resulting hybrid non-viable for reproduction. In order to treat this scenario with the seriousness it deserves, we must first establish two factors. 1, is this very likely to happen? 2, where do the implications fit on a scale with mild inconvenience at one end, and world ending catastrophe at the other?

It seems to me, that the risk of a weed acquiring resistance to potato blight via this method is both phenomenally remote, and utterly not a problem.

The story is not about weedkiller, it's about fungus.

And which weeds is this potato related to so closely that it could cross pollinate them?

I find that hard to believe, it sounds a lot like the sort of action that would constitute racketeering under the RICO act and result in a massive class action suit.

The same process that can give weedkiller resistance can also assist blight resistance. Though in this case blight resistance might be a non problem. GM needs to be thought through thoroughly before trials begin.

So you want a cast iron certainty that cross species transfer of genetic material can not happen... oh [LIFTED] someone better tell Mother Nature to stop then as it all ready happens.

GM is here and is going to be increasingly important as the world population keeps growing.
