Pharmgrade PHINISHER is one of our longest-running products. It is formulated to trigger the plant to shift its energy from growing foliage to reproduction, resulting in bigger finished tubers and more cwt to the acre. 

PHINISHER should be applied at least 21 days before kill to potatoes. Contact us for usage and application rates on other root crops.
