This study was conducted to evaluate the effect of mecoprop-wp concentrations on weed control, growth characters and yield in flax, after 7cm and 14cm of plant height it to the field. The major weeds were Alopecurus aequalis var. a murensis (kom) ohwi, Persicaria hydropiper spach, Lamium amplexicaule L, Stellaria alsine Grimm var. undulata ohwi, Eleusine indica(L.) Gaertn. Flax yield were increased somewhat more with 250g/10a mecoprop-wp at 7cm of plant height than the other treatment and by hand weeding treatment of mecoprop-wp, 250g/10a at 7cm of plant height was slightly harmful for the flax with recommended concentration, On the other hand, all treatments were harmful in the double dosage level.

This study was conducted to evaluate the effect of herbicides on weed control, growth characteristics and yield in flax, after direct seeding it to the field, the herbicides treated had no effect on the emergence period. The major weeds were decreased some what more with mecoprop-wp, herbicide than the other herbicides and by hand weeding. Mecoprop-wp and simazin-wp were had no injury but sethoxydim-EC and 2.4-D-wp were slighthy harmful for the flax with recommended concentration, On the other hand, all herbicides were harmful in the double dosage level
