SELECTION, ESTABLISHMENT AND MAINTENANCE OF WOODY ORNAMENTAL PLANTS FOR HIGHWAY PLANTINGS - FINAL REPORT

THE POSSIBILITIES OF COMBINING HERBICIDES TO CONTROL A BROAD SPECTRUM OF WEEDS, TO CONTROL ACTIVITY FOR SPECIFIC PERIODS OF TIME, AND TO REDUCE CROP TOXICITY WERE EXPLORED. INITIALLY, MINIMUM CONCENTRATIONS NECESSARY TO CONTROL SPECIFIC NEEDS WERE DETERMINED FOR VARIOUS HERBICIDES, AND COMBINATIONS OF VARIOUS LEVELS OF THESE WERE MADE TO OBTAIN BROAD SPECTRUM WEED CONTROL. IN THE SECOND YEAR, ADDITIONAL HERBICIDES WERE FIELD TESTED, ALONE AND IN COMBINATION, TO DETERMINE THEIR EFFECTIVENESS FOR ORNAMENTAL PLANTINGS. THESE HERBICIDES WERE APPLIED AS SURFACE OR SOIL INCORPORATED TREATMENTS DURING VARIOUS TIMES OF THE YEAR. THE FINAL PHASE OF THE INVESTIGATIONS DETERMINED THE AMOUNT OF RESIDUAL ACTIVITY OF THE VARIOUS HERBICIDE TREATMENTS. /AUTHOR/
