ATRAZINE IS A WIDELY USED SELECTIVE HERBICIDE FOR CONTROL OF BROADLEAF & GRASSY WEEDS IN CORN, SORGHUM, RANGELAND, SUGARCANE, MACADAMIA ORCHARDS, PINEAPPLE, & TURF GRASS SOD. IT IS USED ALSO IN SOME AREAS FOR SELECTIVE WEED CONTROL IN CONIFER REFORESTATION & CHRISTMAS TREE PLANTATION AS WELL AS FOR NONSELECTIVE CONTROL OF VEGETATION IN CHEMICAL FALLOW. ATRAZINE ALSO IS USED AS A NONSELECTIVE HERBICIDE FOR VEGETATION CONTROL IN NONCROP LAND. Selective pre- & post-emergence herbicide used in asparagus, forestry, grasslands, grass crops, roses. Crisazina pre and early postemergence on African oil palm, bananas, citrus groves, coffee, corn, pineapples, sorghum, sugarcane.
