Extract

Witchweed, which parasitizes corn, sorghum, sugarcane, rice, and many other members of the grass and sedge family, was found in 1960 on approximately 167,000 acres of crop land in North Carolina and South Carolina. In 1957, the first year of field studies with witchweed in the United States, there was a general opinion that herbicides would never be feasible for its control. However, Figure 1 shows that witchweed-infested land will respond to methyl bromide, although the cost is prohibitive for field applications.
