Chemical Control of Weed for Rapes ( Brassica napus L. )
초록
This study was conducted to evaluate the effect of herbicides on weed control, growth characteristics and yield in rapes, after direct seeding it to the field. All herbicides treated had no effect on the emergence period, bolting rate of rapes. The major weeds were Cerastium holosteoides var. hallaisanense, Stellaria media Villars, Larnium ampleicaule L., Lobelia chinensis Lour., Geranium wilfordii Maxim. and Capsellu bursa-pastoris (L.) Medicus. Rapes yield were increased somewhat more with alachlor-G, herbicide than the other hehicides and by hand weeding. Alachlor-G and alachlor-Ec were had no i j u r y but butachlor- G and simajin-Wp were slightly harmful for the rapes with recommended concentration. On the other hand all hehicides were harmful in the double dosage level.
