Fahrenheit™ Herbicide 38% water soluble granule produces visible activity in 7-10 days. It can be applied in spring, summer and fall with temperatures 50 degrees and above. Fahrenheit contains 33% Dicamba, 5% Metsulfuron-methyl.
Fahrenheit™ herbicide contains two modes of action: Group 2 and Group 4. As a Group 2 herbicide, metsulfuron-methyl inhibits acetolactate synthase (ALS) responsible for the synthesis of essential amino acids that are necessary for plant growth. As a Group 4 herbicide, dicamba is a synthetic auxin that mimics the natural plant hormone indole acetic acid (IAA) causing rapid, abnormal cell growth further leading to a blockage of phloem vascular tissue.
