| Abstract: | Objective] The aim of the study is to reveal the control effect and safety of 15% clodinafop-propargyl WP against weed in wheat field.Method]180,240,300 sand 450 g/hm2 of 15% clodinafop-propargyl WP were designed as treatments,105 ml/hm2 of 6.9% fenoxaprop-p-ethyl EW and water were regarded as normal control and blank control.The incidences of weed were investigated on the 15th and 30th d after the first spraying for calculating the control effect.Result] 15% clodinafop-propargyl WP preformed well in controlling the weed of Alopecurus aequalis S.in wheat field,no obvious influence on growth and development of wheat.Conclusion] 15% clodinafop-propargyl WP is a pollution pesticide that could be generalized in production due to its efficient control effect against Alopecurus aequalis S.in wheat field. |
