CHEMICAL WEED CONTROL

THIS STUDY EVALUATES HERBICIDES AND HERBICIDE COMBINATIONS FOR ROADSIDE WEED CONTROL AND CONTROL OF DIFFICULT AND OBNOXIOUS WEEDS. DEVELOPMENT OF SPECIFIC NEW WEED CONTROL PRACTICES WAS CONCERNED PRINCIPALLY WITH TORDON - 2, 4-D COMBINATIONS WHICH HAVE PROVEN TO BE POTENT HERBICIDES FOR CONTROL OF A WIDE RANGE OF BROAD-LEAVED HERBACEOUS AND WOODY ROADSIDE VEGETATION WITHOUT INJURY TO DESIRABLE SPECIES. WITH MOST PERENNIAL AND BIENNIAL SPECIES, TREATMENT IN THE FALL WHEN TRANSLOCATION OF ASSIMILATES WAS LARGELY TO BELOW GROUND PARTS, WAS FOUND MOST EFFECTIVE IN PREVENTING REGROWTH. THE FINDINGS POINT TO THE POSSIBILITY OF AN EVENTUAL THREE-YEAR (ENVIRONMENTALLY SAFE) SPRAYING ROTATION IN COMBINATION WITH ONE-CYCLE MOWING WHICH CAN BE DEVELOPED INTO A MAXIMUM-BENEFIT, LOW-COST MAINTENANCE PROGRAM FOR INDIANA ROADSIDES WITH COST SAVINGS IN EXCESS OF $300,000 ANNUALLY.
