Registered Tank Mixes
Fertilizers:
Liquid products may be mixed with liquid nitrogen fertilizer (e.g., 28-0-0) for pre-plant soil incorporated
application. Before the herbicide is added to the tank, compatibility of herbicide to the liquid fertilizer should be
tested following instructions on herbicide label.
Trifluralin liquids may be blended with dry bulk fertilizer. Application should be made as soon as possible after
blending. With the exception of ammonium nitrates, all other commonly used dry fertilizers may be used for
trifluralin liquid impregnation.
