This brought to mind work I saw at the University of Idaho on nematode
control by application of rapeseed meal. The glucosinolates (horse-radish
hot stuff) in the meal break down to make volatile isocyanates (just like
Vapam). But if my memory serves me correctly, most canola has been bred to
be free of glucosinolates, specifically so the meal can be fed to cattle.
High glucosinolate meal, perhaps from certain industrial rapeseed cultivars
might be cheaper because it cannot be fed.

But, who cares, it's just going to rot in the soil.

Is that any more evil than supporting all the rest of the industry?
PS: You can also fumigate your soil by plowing down various Brassica or
Raphanus green manures that contain glucosinolates. Saad Hafez at the Parma
R&E Center, Parma, ID has done a lot of work on this.
