Research Progress on Worst Weed Elsholtzia densa Benth.in Spring Rape Fields
Elsholtzia densa Benth.,a worst weed,seriously affects the yield and quality of spring rape in fields.In this paper,we reviewed biological properties,chemical composition,economic characterization and control practices of E.densa Benth.,combined with literature to realize the weeds ways and research progress and the control pathways and research progress in the aspects of agricultural,physical,biological and chemical control,and prospected in the control and utilization in the future.The development and screening of new herbicides and the exploration of herbicide application methods are important ways to address injury of Elsholtzia densa Benth.to spring rape in fields.Therefore,it was recommended to strengthen the monitoring of changes in occurrence trend,development of herbicides-resistant levels in response to climate change scenarios,and research of high efficient and green techniques and methods to control its injury.Meanwhile,E.densa Benth.with high medicinal value could be utilized to treat cold,fever,heatstroke,acute gastritis and other diseases,and has a potential future in the development of anti-hepatocellular carcinoma drugs,so it is recommended to explore its potential in medicine.
