noxious weeds, noxious weed control, smother crops, 2, 4-D
This outline has been prepared as a guide for field workers in weed control; for county, township, and neighborhood supervisors and for farmers cooperating in the program. The control measures presented here are based on the latest information available from weed control research and proven field applications. A choice of methods and procedures is presented that will fit practically all situations. It is assumed that local practices will be kept within the limits of recommendations outlined. Each of the eight weeds listed as noxious will be considered and recommendations for the use of intensive cultivation with various crops will be outlined for each weed. The choice of procedure to be adopted will depend on several factors, namely: (1) extent of infestation; (2) value and productivity of the land; (3) availability of material, equipment, and manpower; (4) adaptability of control practices, and (5) adaptability of crops. If chemicals are to be used, Experiment Station Circular No. 69 should be obtained. The recommendations given in that publication should be followed closely. Colored plates of the noxious weeds which show pictures and give characteristics of these weeds are also available. Copies of the Circular No. 69 or the colored plates can be obtained from the County Agent's office or from the Bulletin Department at South Dakota State College, Brookings, South Dakota. Some cultural practices that are recommended for weed control involve long periods of intensive cultivation. Those that leave the soil barren during the winter are conducive to soil erosion. ln areas where this condition is a hazard the practice should be modified to conform with recommended soil conservation practices.
