Soil applied herbicides in dry weather can be a bit of a concern for producers who are depending on them. In order for the herbicides to work effectively they need moisture to activate them and move them downward through the soil into the area where the weeds have germinated. Unfortunately, no moisture, no migration through the soil. The timing of that moisture matters as well. If it comes too long after that initial germination, the herbicide can have little to no effect.
