Extract

Imazaquin (Scepter) is a new, broad spectrum herbicide that is being marketed under the trademark Scepter® herbicide by American Cyanamid Co., Princeton, NJ. It can be applied preplant incorporated (PPI), preemergence (PE) or over-the-top postemergence (POST) in soybean. Crop tolerance is excellent with all methods of application. Imazaquin was tested in the United States in 1984 and 1985 under an Experimental Use Permit (EUP). Section 18 Emergency Exemptions also were granted by the Environmental Protection Agency (EPA) in 1985 for control of sicklepod (Cassia obtusifolia) in five southern states. Imazaquin was registered by the EPA for use in the United States on soybean, in March, 1986, and was sold in 23 states that year. Marketing in four additional states in 1987 was approved by the EPA in October, 1986.
