摘要
Abstract
The study revealed the control efficacy of Quizalofop-P-ethyl 15.8％ EC against Bromus tectorumL.and Avena fatua L.as well as its safety in spring rape fields.The treatment included 225,300,375 and 600mL/ha of Quizalofop-P-ethyl 15.8％ EC.The 300mL/ha of Quizalofop-P-ethyl 15％ EC was used as herbicide control, and manual weeding and water were regarded as negative control.These herbicides were sprayed during 2-5 leaf stage of rape with 300 L water (1-4 leaf stage of Bromus tectorum L.and 2-4 leaf stage of Avena fatua L.).The incidence of weeds was investigated on the 20 th and 40 th days after the first spraying for calculating the control effects.The results of field trial showed that Quizalofop-P-ethyl 15.8％ EC preformed well in controlling the weeds of Bromus tectorum L.and Avena fatua L.and the suitable dosages were 375mL/ha and 300mL/ha, respectively.Quizalofop-P-ethyl 15.8％EC effectively controlled Bromus tectorum L.and Avena fatua L.and could be used widely in spring rape fields.关键词
