Product Overview

PrecisionPac® FH-20 herbicide may be used as a harvest aid to accelerate the rate of crop dry down and improve crop uniformity to facilitate direct combining.  Early application may result in yield and/or seed quality loss.  The dry down of crops will be best under favorable environmental conditions like warm temperatures, good moisture conditions and low humidity.

Harvesting of crops can be done when plant materials is dry and seed moisture level allows efficient harvesting.  Under ideal conditions, harvest can normally commence within 7-21 days after application when applied at the appropriate crop stage recommendation.
