Yellow nutsedge (Cyperus esculentus L.) is one of the most serious weeds in New York State. This weed has an extensive distribution in the state where it is a strong competitor with row crops especially corn, beans, and potatoes. Nutsedge is also an important weed problem in many other leading agricultural areas of the United States. The problem in all of these areas has increased recently, possibly due to a reduction of competition from other weeds which are being satisfactorily controlled by selective herbicides.
