CONTROL OF COGONGRASS (IMPERATA CYLINDRICA)

COGONGRASS (IMPERATA CYLINDRICA) IS A WEEDY PERENNIAL GRASS NATIVE THROUGHOUT THE OLD WORLD BUT INTRODUCED MORE RECENTLY INTO THE WESTERN HEMISPHERE COUNTRIES INCLUDING SOUTHEASTERN UNITED STATES. LARGE CLUMPS OF COGONGRASS GROWING ON THE SHOULDERS OF HIGHWAYS CAN CAUSE SEVERE SIGHT DISTANCE PROBLEMS THAT ARE DIFFICULT TO CORRECT DUE TO ITS AGGRESSIVE GROWTH HABITS. TESTS CONDUCTED FOR THREE YEARS IN ALABAMA INDICATED THAT SINGLE APPLICATIONS OF MOST POSTEMERGENCE HERBICIDES GAVE SOME INITIAL TOPKILL OF COGONGRASS BUT CONTROL LASTED LESS THAN ONE YEAR. MULTIPLE APPLICATIONS (FIVE APPLICATIONS PER YEAR) OF DALAPON, AMITROL AND PARAQUAT GAVE SIGNIFICANT REDUCTIONS IN COGONGRASS STANDS ONE YEAR LATER.
