Why is the lower limit on the label for application 60 degrees - is that for the glyphosate, or is the pre-emergent performance of imazapyr affected by temperature?
Since plants will not be actively growing when the roots are too cold. Post-emergent herbicides like Agrisel GlyPhoSel Plus Herbicide are going to work best when the air temperatures are between 55-85 degrees. Some products will have better cool-weather performance down to about 45 degrees.
