1971 ANNUAL REPORT, "VEGETATION CONTROL ON ROADSIDES AND SIMILAR AREAS"

THE DISCOVERY OF HIGHLY ACTIVE HERBICIDES HAS PERMITTED MORE EFFECTIVE WEED CONTROL. HOWEVER, CHEMICAL DRIFT IS A PROBLEM WITH THESE HIGHLY ACTIVE MATERIALS, AND THERE IS A NEED FOR SAFER APPLICATION TECHNIQUES. THE USE OF THICKENED SPRAYS TO REDUCE SPRAY DRIFT IS BEING INVESTIGATED. LABORATORY TESTS HAVE BEEN CONDUCTED TO OBSERVE THE CHARACTERISTICS OF THESE SPRAYS UNDER VARYING CONDITIONS. LATER THIS SPRING, DRIFT REDUCTION WILL BE MEASURED IN ORDER TO EVALUATE THICKENED SPRAYS AS A MEANS OF REDUCING SPRAY DRIFT. EVALUATIONS WERE MADE OF COMMON MILKWEED CONTROL ON ROADSIDES FROM TREATMENTS APPLIED IN THE SUMMER OF 1970. MALEIC HYDRAZIDE WAS APPLIED TO TALL FESCUE FOR THE PURPOSE OF HOLDING THE PLANTS BACK, THEREBY POSSIBLY REDUCING MOWING. SOIL STERILANTS APPLIED IN THE SUMMER OF 1970 WERE EVALUATED, AND ANOTHER SERIES OF APPLICATIONS WERE MADE IN THE FALL. /AUTHOR/
