DIURO 80 SC

INTRODUCTION: Diuro 80 SC: diuron (DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea) is a residual urea herbicide effective against a wide range of both annual broad leaf weeds and annual grasses. It is applied prior to weed emergence in crops and plantations or as a soil sterilant in non-crop areas. It needs activation by rain or irrigatation. Combinations of Diuron with contact herbicides such as 2,4-D, Diquat, Paraquat, MCPA etc., will effectively control established weeds and prevent the emergence of new weeds. Diuron is absorbed via the root systems and through foliage and stems in the case of young seedlings. Diuron requires rainfall or irrigation to ensure that it penetrates to the root zone and so may be taken up. Uptake is primarily via the xylem and the toxic action relies upon inhibition of the Hill reaction and ensuing impairment of photosynthesis and thus reduces the ability of the plant to turn light energy into chemical energy (ATP and reductant potential).
