Preharvest herbicide applications in dry edible beans- Avoiding illegal residues
Preharvest herbicide applications in dry edible beans have become more popular as growers switch to direct harvesting techniques. Herbicides used prior to harvest, also known as “Harvest Aids”, are used to desiccate or dry down “green” stem and leaf tissue that can hinder dry bean harvest. The main intention of preharvest herbicide applications is to desiccate weeds; however many growers are using these herbicide applications to hurry along or even out the maturing process of dry beans.
