REPORT ON USE OF MALEIC HYDRAZIDE FOR TEMPORARY GROWTH INHIBITION OF GRASS

APPLICATION OF MALEIC HYDRAZIDE (MH) IS SUGGESTED ONLY FOR ESTABLISHED TURF AREAS. SINCE APPROXIMATELY 24 HOURS ARE REQUIRED FOR COMPLETE ABSORPTION OF AN MH SPRAY, RAINFALL RECORDS WITHIN THIS PERIOD WILL ASSIT IN INTERPRETATION OF RESULTS. A FALL SPRAY OF 4 OR 6 POUNDS OF MH IN NOT LESS THAN 40 GALLONS OF WATER PER ACRE APPLIED TO GREEN TURF IS SUGGESTED. MOWING AFTER APPLICATION IS NOT REQUIRED. AN EARLY SPRING APPLICATION AT 4 OR 6 POUNDS IS NOT LESS THAN 40 GALLONS OF WATER PER ACRE APPLIED TO GREEN GRASS AT START OF GROWTH OFFERS RESULTS EQUIVALENT TO FALL TREATMENT. SUMMER SPRAYING OF 4 TO 6 POUNDS IN NOT LESS THAN 40 GALLONS OF WATER PER ACRE INHIBITS GRASS BUT NOT TO THE DEGREE RESULTING FROM EITHER FALL OR SPRING TREAMENT. IF A MOWING IS NECESSARY TO TRIM AN AREA, ONE WEEK SHOULD BE ALLOWED TO ELAPSE BEFORE MOWING IS MADE, FOR ABSORPTION AND TRANSLOCATION OF MH TO ROOTS. RETREATMENT WITHIN THE SAME SEASON CAN BE MADE AFTER THE GROWTH HAS RESUMED. NO MORE THAN TWO APPLICATIONS IN ONE SEASON ARE RECOMMENDED AT THIS STAGE OF DEVELOPMENT. PRESENCE OF BROADLEAVED WEEDS IN PLOTS WILL REQUIRE INCLUSION OF 2, 4-D AS AMINE SALT AT LOCALLY RECOMMENDED DOSAGE.
