Study on action mechanism of new carbamate herbicide WD of Descurainia Sophia

Morphlogical effects of a new carbamate herbicide WD on dicotyledon weed Descurainia sophia (L.) Sehur was that the plant growth has been inhibited, the steam and root was thinking and harding. While anatomical characters were that the meristematic zone cell of steam tip has been disrupted, it was inhibited vescular cambical cells differentiate seeondary xylem and phelom, In the other hand, the cortical cell lays was raised in steam and root. The obtained results show: weed leaves and teams can adsoption WD, and transprate it to meristematic zone with the production of photosynthetic.
