| Abstract: | Experiment with 5 kinds of herbicides and 20 treatments were applied to controlStellera chamaejasme in June 1997. The results showed that the control efficiency of A3,A4,B1, B5 and B6 were 9O. 2%, 90. 2%, 92. 3%, 95. 8% and 81. 0%, respectively and their mainproponent was 2,4-D. The other treatments were not satisfactory. The drown plant couldnot turn green because their root necrosised and decomposed. |
