通过调查50 g/L唑啉草酯EC对小麦田禾本科杂草的防除效果及对小麦的安全性,发现在早春气温回升、小麦苗体较大时使用该药剂60~75 g/hm2除草的综合防效达85%以上,若用量提升到112.5 g/hm2则会引起药害,典型受害状是小麦叶片上产生褪绿斑块,但对小麦产量影响不大,安全性尚可。 By investigating the control effect of 50 g / L pinoxaden EC on grass weeds in wheat field and its safety to wheat, it was found that in the early spring when the temperature rose and the wheat seedling body was larger, the herbicide 60 ~ 75 g / hm2 was weeded Of the total control efficiency of more than 85%, if the amount increased to 112.5 g / hm2 will cause injury, the typical victims of wheat leaf chlorotic plaque, but little impact on wheat yield, safety is acceptable.
