[QUOTE="cowtrek, post: 428718, member: 2847"] No Roundup will not kill the ryegrass seed. Glyphosate bonds very tightly to soil molecules very quickly after hitting the ground and is deactivated, that's why it has no soil activity. The only seed you have to worry about killing with Roundup is the seed inside cotton bolls sprayed after the fifth true leaf stage; the glyphosate would hang around inside the cotton plant long enough to sterilize the pollen in the blooms, and the cotton plant would sense that the bloom didn't have enough fertilized ovums (seeds) inside the square and shed the young boll before it could develop. Some bolls that did have enough seed to be retained by the plant would end up with a hooked tip that wouldn't allow the boll to open properly, which prevented mechanical spindle picking or efficient stripping. This is why RR cotton had to be sprayed before the fifth true leaf stage, the glyphosate was long gone before the squares started to form and wouldn't sterilize the pollen. The genetic engineers have since 'fixed' that problem with RR 2 technology. You said Texas so I don't know if you're talking about wild ryegrass that we have around here, which takes the roadsides completely over from January til about May but that will come on perfectly well on its own without doing a thing. I have seen it come in under dead grass and weeds along the roadside and just completely overtake it. Frost will do for free what the Roundup will cost you to do. I doubt you'd really need to do much of anything to get this stuff to come on; ryegrass comes up pretty well just lying on the surface, especially the wild stuff.
