不同除草剂对树莓中菟丝子防治效果

Control Effect of Different Herbicides on Cuscuta Chinensis in Raspberry

以多年生小浆果树莓林地为试验地块,对树莓上的日本菟丝子喷施3种除草剂,观察防治菟丝子的效果及对树莓生长的影响,以期为树莓林地防治日本菟丝子提供参考。结果表明:三种药剂,药后30d对菟丝子均有一定的防除效果,其中大葱专用除草剂120倍液,施药后30天防效达到88.4%,对树莓产生轻度药害,15d后可正常生长,菟丝子全部枯萎,防效最好,且对树莓生长影响最小。6%的草甘磷水剂200倍液和仲丁灵500倍液,防效分别达到59.3%,50%,并产生药害,进入寄主部位的菟丝子能继续生长。

Taking the perennial raspberry woodland as the experimental plot,three kinds of herbicides were sprayed on Cuscuta japonica on raspberry to observe the control effect of Cuscuta chinensis and its influence on raspberry growth,so as to provide reference for the control of Cuscuta japonica in raspberry woodland.The results showed that:the three fungicides had certain control effect on Cuscuta chinensis 30 days after treatment.Among them,the control effect of the special herbicide 120 times for scallion reached 88.4%after 30 days of application.The control effect on raspberry was slight,and it could grow normally after 15 days.The control effect of 6%glyphosate 200 times and zhongdingling 500 times were 59.3%and 50%respectively,which caused damage.The dodder that entered the host part could continue to grow.
