15%炔草酯WP防除小麦田杂草及安全性研究

Study on the Weed Control and Safety of 15% Clodinafop-propargyl WP in Wheat Field

[目的]明确15%炔草酯WP对小麦田杂草的防除效果和安全性。[方法]以15%炔草酯WP 180、240、300、450 g/hm2用量喷雾,以6.9%骠耙EW 105 ml/hm2为对照,以清水喷雾为空白对照,药后153、0 d调查杂草数计算防效,并观察药害情况。[结果]15%炔草酯WP对小麦田看麦娘具有很好的防效,对小麦生长发育无明显影响。[结论]15%炔草酯WP是防除小麦田看麦娘杂草的一种无公害农药,可以在生产上推广使用。

[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/hm^2 of 15% elodinafop-propargyl WP were designed as treatments, 105 ml/hm^2 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 obvions 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 aequdis S. in wheat field.
