Abstract/Contents:Presents a study conducted in Arizona during 1967 to determine "the proper rate of monosodium acid methanearsonate (MSMA) for the control of nutsedge." Details methods and materials used during the experiment, noting that "one hundred and forty-four nutsedge tubers were planted 6 feet apart in rows 10 feet apart in July of 1966 and were allowed to grow vegetatively." Reports that "applications of 3 pounds per acre (lb/A) of MSMA [monosodium acid methanearsonate] failed to destroy topgrowth of nutsedge and plants continued to spread." Provides a table showing the number of nutsedge plants that survived and the number of stems per living plant after repeated applications of MSMA. Concludes that higher rates of MSMA "[are] not usually selective in bermudagrass but could be used where sprays do not contact other plants."
