| Abstract: | Bromus tectorum L.and Avena fatua L.are the main weeds in Qinghai spring wheat fields,occurring generally and causing serious damage.In order to control them,6 herbicides developed currently for controlling gramineous weeds of wheat fields were selected in field experiment.The results showed that 600mL/ha of 50g/L Topik-pinoxaden EC,300g/ha of 150g/L Clodinafop-propargyl and 750mL/ha of 69g/L Puma super EW had over 90% efficacy on Avena fatua L.,and 7.5% Pyrosalam+cloquintocet WG had good effect on the Bromus tectorum L.,with 100% efficacy for plants and fresh quality.These herbicides were safe to wheat and wheat yield was increased significantly,therefore they were appropriate for large use in Qinghai spring wheat fields. |
