I don’t know how widespread this problem is, but an online friend in Wyoming says that ALL the wheat fields in her area have been plowed under instead of being harvested. She says that, according to the farmer she talked to, it’s because the fields were so heavily contaminated with feral rye, that they’re not worth the cost of harvesting.
I’m pretty sure 2 of the wheat fields in my area had similar contamination last year. It’s really obvious when the wheat is a dwarf variety, which most are these days. It’ll be interesting to see what’s planted in those fields this year.
Given the probable worldwide shortage of grain this year, they should be harvesting this mixed grain and sell it as premixed rye bread flower.
