I think this depends more on the year & climatic conditions. I'm sure you & others do a good job spraying, that's not a question. But, I have to say in this area (NE IL), we seem to be having a good kill this yr from glyphosate. On our corn I often tank-mix the other "outdated herbicide" of atrazine w/the glyphos, but mostly for residual effect. I use a low rate of atrazine, which is reportedly speeding resistance, but I'm not sure what a full rate of atrazine would be for post apps re. weed control & not EPA concerns.

In beans we're just 100% glyphos, except for adding some type of lo-rate anti-vol corn compound where RRC was planted previous year. However, we're no longer 50/50 corn-bean rotation here. I really don't think anyone is locally either. So, due to "pre" corn compounds & possible post tank-mixes in corn, we've strayed a long way off the monoherbicide lifestyle. We're 100% RRC & RRSB.

Now, we have no nt sb or corn, so nt could be a different issue w/the early winter annuals etc. TWH is a problem here, but it seemed this yr that if you sprayed the weed, it died. Residual (or the lack of it) is certainly another concern. Many other older products had residual capability to some extent.
