HERBICIDES FOR ROADSIDES IN LOUISIANA

TO DETERMINE THE USEFULNESS OF HERBICIDES IN A PROGRAM OF VEGETATION MANAGEMENT ALONG LOUISIANA ROADSIDES A CONSIDERABLE VOLUME OF INFORMATION REGARDING CHEMICAL WEED KILLERS AND THEIR APPLICATION WAS OBTAINED FROM 8 STATE HIGHWAY DEPARTMENTS, UTILITY COMPANIES, INDUSTRIAL ORGANIZATIONS AND PARISH MAINTENANCE PERSONNEL. IMPORTANT AND VOLUMINOUS SPACE IS DEVOTED TO A REVIEW OF COMMON SPECIES OF HERBACEOUS WEEDS AND THEIR WELL-KNOWN CHARACTERISTICS AND TO PHOTOGRAPHS AND EXPLANATORY NOTES INTENDED TO EMPHASIZE VARIOUS FACETS RELATED TO VEGETATION SITUATIONS AND EQUIPMENT. FIFTY TWO PLOTS MEASURING 300 FEET BY 20 WERE TREATED WITH 5 CHEMICALS APPLIED AT VARIOUS RATES AND OBSERVED VISUALLY FOR A PERIOD OF SEVERAL MONTHS. ALTHOUGH VARYING DEGREES OF KILL ARE DESCRIBED THE LONE TABULATION PRESENTED IN THE REPORT LISTS RESULTS IN TERMS OF EFFECTING PLANT GROWTH - SLOW, MODERATE, NORMAL. THE REPORT CITES THE URGENT NEED FOR REDUCING VEGETATION CONTROL /ESPECIALLY MOWING/ COSTS AND CONCLUDES THAT' TESTING OF HERBICIDES SHOULD BE DONE ON SMALL PLOTS AND WITH PILOT TESTS TO AVOID COSTLY MISTAKES IN EMPLOYING HERBICIDES. THE HERBICIDE PROGRAM SHOULD BE LIMITED, AT FIRST, TO TREATING VEGETATIVE GROWTH AROUND OBSTRUCTIONS SUCH AS CULVERTS, SIGNS, ETC. COSTS OF HERBICIDE IS ALSO REDUCED BY TREATMENT OF COMPARATIVELY SMALL AREAS INSTEAD OF ATTEMPTING TO TREAT THE ENTIRE ROADSIDE. /BPR/
