      note = {This publication, the fourth of a series of reports that  has appeared during the last 10 years, updates the  information on the extent and cost of weed control with  herbicides in the United States to 1968.  It also contains  evaluations of important weeds.  These evaluations are much  more comprehensive than those in any of the three preceding  publications.  Thus, this publication represents the most  recent evaluation of the current status of herbicide usage  in all States and the important weeds against which  herbicides are directed.  In conjunction with summary data  from the earlier publications, it serves as a prospectus of  chemical weed control for the immediate future.  This study  was made possible by the close cooperation of State  research and extension workers and three agencies of the  U.S. Department of Agriculture:  the Economic Research  Service, the Agricultural Research Service, and the  Extension Service.  All shared in planning the study and in  writing the report.},
      abstract = {Excerpt from the report Introduction:  The U.S. Department  of Agriculture recognizes that all measures for controlling  weeds must be used to reduce losses in crop production.   Integrated weed control programs must include time-tested  control measures, such as cultivation, mowing, burning, use  of weed-free seed, crop rotation, and fertilizer practices,  as well as herbicide control measures.  Some biological  controls have been developed and integrated into the  programs; others are being developed.  In the foreseeable  future, however, herbicides will continue to hold the  greatest promise for checking and reducing the losses  caused by weeds in many programs of production.  The  current survey has been designed to provide more precise  basic information on the economics, costs, and  effectiveness of herbicides and the weeds against which  they are used.},
