Not without controversy, applying glyphosate prior to harvesting a crop can help with crop and weed dry-down. If done too early, while the plant is still moving nutrients up into the kernels, a pre-harvest pass can cause glyphosate residues in the resulting grain.
That's always a concern when residue is possible, but mounting pressure against glyphosate use overall has put the practice of pre-harvest use under the spotlight.
Even when used on-label and at the correct time, an increasing number of grain buyers have pre-emptively said they'll only buy certain crop types if they haven't been treated with a pre-harvest pass.
We want to know — if you use glyphosate pre-harvest, are you doing it more, less, or the same?
