We always add a qt of 51% 5 or 6 lb gly every time we spray beans & corn regardless of what else is in the tank mix. That’s just the standard recommended rate spraying over top of crop. When I’m trying to kill Bermuda grass or gravel roads I spray a 2 qt rate.

I’ve got an unusual hobby of traveling through Mid-West visiting farm shows & field days during Summer. One of their primary concerns is herbicide resistance. They blame problem on low rate applications. The government & universities recommended lower rates when Roundup was a patented product and cost 10xs what it does now. Took them a few years to figure out what they had done recommending low rates. Gly is so cheap now that there’s no reason to spray low rates
