Got a line on some organic hard spring wheat, 10 $/bu. Have to drive a ways, but that's OK. But I wonder if it's food safe? I've heard that run-of-the-mill seed is generally treated with pestiside... I've seen sweet corn seed that's red from whatever they treat it with. I've also read that DE, silica, and controlled atmospheres are the only way to treat organic grain. But I haven't found anything specific to organic seed. Any thoughts?
