Harvest aids don’t work in cool conditions

Farmers are asking if there’s anything they can apply to get harvest moving. The answer is no, nothing that comes from a bottle. A return to warm, dry conditions will get harvest progressing again.

Glyphosate in cool conditions will do nothing to dry plants down. Heat and diquat-based desiccants, like Reglone, need sun and warm conditions to work properly. Frost is nature’s desiccant, as ice crystals, forming inside plant cells, puncture cell membrane and cause cell contents to leak.
