Description
Cable-type backrubbers, soaked with a 5 percent oil solution of DDT, have been in use for the control of horn flies on range cattle since about 1946. Their use has been spreading steadily despite the small amount of publicity given them by state and federal research agencies and by commercial organizations. Certain information concerning this method of insecticide application has been released by the South Dakota State College Agricultural Experiment Station in the annual reports of 1950 and 1951.
Research data now indicate that the use of backrubbers as described in this bulletin will result in effective control of horn flies on cattle. Two seasons of careful observations have failed to reveal any objectionable skin irritation resulting from this method of insecticide application. Chemical analyses of fat from cattle using cable-type backrubbers for an entire season show about one eighth the amount of DDT that has been found in the fat of cattle which were sprayed three times according to standard recommendations.
