【Abstract】 [Aims] This paper aims to determine the efficacy and safety of dazomet 98% MG against weeds in ginseng field to provide basis for registration and application of dazomet in ginseng production. [Methods] By soil fumigation treatment in field at two locations from 2016 to 2017, dazomet 98% MG were tested to determine the application doses and safety for controlling weeds in ginseng field. [Results] By soil fumigation treatment in the ginseng bed at the doses of 15, 30 and 45 g/m2, the total plant number and fresh weight overall control effects of dazomet 98% MG against the annual weeds including Commelina communis, Chenopodium album, Conyza canadensis, Echinochloa crusgalli,Polygonum lapathifolium, Glycine soja and biennial weed Rorippa islandica were 76.04-91.46% and 77.77-92.73%,respectively at 45 th day post emergence. No herbicide-injury was observed on ginseng. [Conclusions] Dazomet 98%MG can be used to control weeds in ginseng beds showing better control effects against weeds in ginseng field and safety to ginseng growth.更多还原
