The application of 2,4-D amine herbicide for control of weeds infesting sugar cane fields, produced teratogenesis and affected the sugar cane plants. The anatomic and organografic alterations of the teratogenic forms were studied and compared with normal structures. Stalk malformation was observed, resulting in bending and thinner stalks; root system had little development. The growth ring and root band showed severe hypertrophy, callus formation and necrosis. The growth ring, the epidermis and cortical parenchyma showed hypertrophied cells and disturbed growth. Malformation of phloem and xylem also ocurred.
