Adding ammonium to herbicides like Goal, Reflex and Cobra
increases the phytotoxicity to weeds. Farmers often
add ammonium nitrate to herbicides to act as an adjuvant.
The ammonium ion also can increase the “burn” on
newly formed needles. To reduce injury, many managers
apply irrigation soon after applying the tank-mix.
Not all herbicides respond this way.
