That's right, Tyler. Re-introducing it to the field is the killer, is considered baiting, and well should be, IMO. It is absolutely not necessary.
George, I used to strip plant like that, but finally quit in favor of 100% sunflowers. There is Round-up Ready corn, of course, which can be oversprayed with glyphosate, but there never has been a Round-up ready version of sunflowers. What there is, is Clearfield sunflower seed, which can be sprayed with Cadre, primarily a broadleaf herbicide. Our pigweed had gotten resistant to Cadre, but I found a "new" herbicide that is the best stuff I have ever found for sunflowers. It is called Spartan, and MUST be sprayed pre-emergence, or before the sunflowers emerge after planting.
I have the cleanest field I have ever had, this year, due to trifluralin incorporated prior to planting, and Spartan pre-emergence. As you know, one of the keys to having a field attractive to doves is the ground under the crop being clean and bare. I'll take some pictures this afternoon and you can see what I mean.
I'm off to shoot a field near Louisville. We draw stands at about 6:30 a.m., so I'd better get crackin'. John Roberts and son Ross will arrive here late morning to shoot with me this afternoon. Gonna be big fun today!!
