Monitoring and management of invasive pest fall armyworm (Institute of Plant Protection)
The monitoring and forecasting techniques, including light traps and pheromone traps, were developed to make early warning of fall armyworm that had invaded China; the online identification service and population dynamics forecasting system were developed; effective chemical pesticides to control fall armyworm were screened and the proper application techniques were proposed; four kinds of biologi... -
Biochar reduces the environmental risk of contaminates in soil (Innovation Team of Mudflat Bioresource Protection and Utilization, Tobacco Research Institute of CAAS)
The Innovation Team of Mudflat Bioresource Protection and Utilization, Tobacco Research Institute of CAAS found that the amendment of functional biochar at proper rate increased the adsorption ability of soil to contaminate like atrazine, reduced their bioavailability and ultimately decreased their accumulation in plants. These results were helpful to develop the biochar remediation technology for... -
New lead compounds used for developing biopesticides with high efficiency and low toxicity (Innovation Team of Tobacco Functional Components and Synthetical Utilization at Tobacco Research Institute of CAAS)
The Innovation Team of Tobacco Functional Components and Synthetical Utilization from Tobacco Research Institute of CAAS characterized new prenylated indole alkaloids (PIAs) from a tobacco-associated endophytic fungus. PIAs possess high antifungal activity against several plant-pathogenic fungi and remarkable larvicidal activity against the cotton bollworm Helicoverpa armigera with low toxicity, s... -
Serial solid organic fertilizer spreaders (Biomass Conversion and Utilization Equipment Innovative Team at Nanjing Institute of Agricultural Mechanization of CAAS)
The Biomass Conversion and Utilization Equipment Innovative Team of Nanjing Institute of Agricultural Mechanization of CAAS has overcome key technical problems in fertilizer spreading, such as stable feeding and uniform spreading.
