After looking at your link, I agree. That's it ! It's all in a corner of my plot and I was surprised to even see it, and more surprised at how it was being browsed. Do you think it came in the IC pea seed ? I've never seen it on my place before. I know for a fact that I've gotten sicklepod in peas and soybeans. It still shows up each year even though I usually hand pull the plants well before they flower. Thanks for your help !
