Should I go with an advisor whose area isn't precisely what I want?

[F.graminearum]

It's getting to the point where I may not get accepted anywhere else. I was put in contact with a potential advisor who is looking for students but is very molecular oriented (completely lab based with some greenhouse trials), while what I'm looking for is more applied (field trials). Should I go with this guy, who said he would try to fit a field component in or should I call continue with my current job and give up on going to grad school?

Does your current job help you in advancing towards an area of research that you would be interested in pursuing? If it doesn't help you at all you should consider a change of job and then apply again in a couple of years when you've gained more experienced and have a stronger application. No point in being miserable or giving up on going to grad school if you absolutely know that's what you want.
