Extract

Since 1951 a number of reports on the use of pre-emergence herbicides for cotton have been published, and in several cases, these reports included data on the reduction of hand labor following the use of chemicals. In 1956, McWhorter et al. reported that combining chemical treatments with cross-plowing resulted in even greater reductions of hand labor than by the use of chemicals alone. They also reported that even though the amount of hand labor was reduced, both by the use of chemicals alone and by a combination of chemical and mechanical means, a corresponding reduction in the overall weed control cost did not always occur.
