Weed Chemical Control in Radix Glehniae Fields |

Abstract: | [Objective] The aim was to explore the suitable herbicide on broadleaf weeds in Radix Glehniae fields and its using technology.[Method] Weed control effect of fenoxaprop-P-ethyl,halosulfuron methyl,bentazone,isoproturon and a mixture of fomesafen with quizalofopP-ethyl in Radix Glehniae fields were studied through a plot experiment.[Result] The preliminary results revealed weed control effect of fomesafen mixed with quizalofop-P-ethyl in Radix Glehniae fields.At 45 days after application of mixtures of 25% fomesafen EC (375 g a.i./hm2)with 10% quizalofop-P-ethyl EC (67.5 g a.i./hm2),the weed control effects for the overall weed stem control effect and fresh weight control were approximately 75% and 80%,respectively,and the herbicide mixture was safe to Radix Glehniae.[Conclusion] The mixture of fomesafen with quizalofop-P-ethyl could be application for weed control in Radix Glehniae field after future study in applied technology and provide a reference for effectively solving harm of broadleaf weeds in Radix Glehniae field. |
