Vining legume is good companion, preferably a heat-loving / warm season species like lablab bean, velvet bean or a climbing cowpea. For more northern locations, perhaps forage soybean (does not require quite as much heat to thrive) - be sure to choose a forage type for your region or (best) a couple of "maturity groups" further south - these will give the most vegetative growth.
More: Vetch or field pea was suggested before- but these are cool season crops and will thrive only at temperatures too low for sudex. But perhaps (given enough soil moisture) with a mid-late summer planting, the sudex will grow first, then slow down and die while vetch/peas come to life in the fall and climb up the sudex stalks.
Thanks for the comment! One of our eOrganic members from Oregon State University has some ideas for you:
I've wondered the same thing. I've never mixed sudex with a legume, but when planted on its own I've seen very good control of pigweed. I think I've heard that the prussic acid in sudex is allelopathic. Regardless of that, it is very competitive. A vining legume like vetch or perhaps field peas would be the best bet, and to reduce the seed rate of the sudex by half or more.
