Back in the day, we used colchicine to make tetraploid orchids by carefully exposing developing protocorms while still in the flask.  A real pain because you can't sterilize it in the autoclave (the colchicine breaks down).

Now the weapon of choice is minute concentrations of oryzalin, which as many gardeners know, is a dirt-cheap preemergent herbicide.  It's less toxic than colchicine and you can get it at the farmer's co-op.  The only downside is that it is VERY orange, so don't spill it on yourself or anything else or you'll have orange hands for a while.
