MPI:7.5 mg/day for a 60 KG person USES:33% Pendimethalin is a herbicide widely used in water and dry field with character of low toxcity, stable in acid and alkali, less require to soil and long-residue time(40-60 days). It\'\'s a selective herbicide, absorbed by the roots and leaves. Inhibits cell division and cell elongation. Affected plants die shortly after germination of following emergence from thr soil. Applied pre-plant incorportated, pre-transplanting. Comtrol of most annual grassed and many annual broad-leaved weeds.
