The REALLY important thing that scientists need to be working on

Earlier this spring and summer, Tam blogged a few times about her burgeoning crop of maple trees in the yard. Yeah, I had those, too.
But does Tam have wild violets?
I swear I would rather have a yard full of maple trees than a yard full of wild violets. Whoever came up with “see a violet, let it grow” or however that damnfool doggerel goes should have been run out of town on a rail. They proliferate like dandelions and they’re damn near impossible to kill, because apparently they have a root structure very similar to that of grass and killing any one particular violet doesn’t kill the roots. In addition there are genetic similarities that mean you run the risk of killing your grass if you use the few weed eradicators on the market that actually, you know, kill violets.
So with all this smart-guy research that goes on in genetics and so forth, why in hell hasn’t someone sequenced the genetics of wild violets and come up with something that targets them … and NOTHING ELSE?
If they make it, I will buy it. It would have to be cheaper than killing everything in the yard and starting over.
