I'd use bwareaopen() or bwareafilt() to get blobs that are small. Large blobs will be the big crop rows. Of course when the plants are very young it would be hard to tell between a small wheat plant and a small weed. However John Deere has farm machines that drive over the crop rows and use deep learning to spray only the weeds, so it is a solved problem, and probably one that has patents on the concept.
