Uptake and Translocation	Foramsulfuron is quickly absorbed through leaves and rapidly translocated throughout the plant.
Basis of Selectivity	Inhibition of acetolactate synthase (ALS) enzyme in susceptible plants. Tolerant species rapidly metabolize foramsulfuron.
Application Methods	Postemergent from the 1- to 8-leaf stage of corn, emerged grassy weeds up to the early tillering stage, emerged broadleaf weeds.
Residual Activity	Essentially none.
Unique Characteristics	Addition of the safener isoxadifen in the formulated product maximizes crop tolerance, enhances crop recovery under severe environmental conditions and allows the use of an ethylated/methylated seed oil based adjuvant system. Methylated seed oil (Hasten) should only be used with Option 35DF, as Option 2.25 OD does not require the addition of Hasten. Option 35DF is applied at a rate of 100 g/ha or 40 g/ac plus 1.75 L/ha or 0.7 L/ac Hasten.
