PROGRESS REPORT ON USE OF MALEIC HYDRAZIDE FOR GRASS INHIBITION ON HIGHWAY AREAS

THE SYNTHESIS OF MALEIC HYDRAZIDE (MH) WAS FIRST REPORTED IN 1895. THE CHEMICAL WAS PREPARED AND ITS UNIQUE GROWTH-INHIBITING PROPERTIES ON GRASSES WERE OBSERVED IN OUR LABORATORIES IN 1949. MH-SPRAYED PLANTS ARE INHIBITED FOR VARYING PERIODS, DEPENDING ON DOSAGE APPLIED AND STAGE OF PLANT DEVELOPMENT AT THE TIME OF TREATMENT. THE EFFECT IS MOST PRONOUNCED WHEN YOUNG, VIGOROUSLY GROWING PLANTW ARE SPRAYED, WHEREAS APPLICATION OF AN EQUIVALENT DOSAGE TO PLANTS APPROACHING MATURITY MAY SHOW LITTLE OR NO RESPONSE. HIGH DOSAGES MAY BE HERBICIDAL. APPLICATION OF 2 OR 4 LB. OF MH PER ACRE IN THE SPRING AT THE START OF THE GROWING SEASON IS SUGGESTED FOR GRASSES IN THE MEDIAN, AND 4 LB. PER ACRE ALONG GUARD RAILS AND ROADSIDES. APPLICATION TO ESPLANADE AND ROADSIDE AREAS AT 4 LB. PER ACRE IS SUGGESTED FOR THE REST OF THE YEAR. /AUTHOR/
